afnetworking 3.0 迁移：如何 POST 使用 headers 和 HTTP Body
afnetworking 3.0 Migration: how to POST with headers and HTTP Body
我正在尝试向 youtube API 发出一个 POST 请求，其中包含 HTTPHeader 字段和 HTTP body。
以前在 AFNetworking 的 2.0 版中，我以前是这样做的：
NSDictionary *parameters = @{@"snippet": @{@"textOriginal":self.commentToPost.text,@"parentId":self.commentReplyingTo.commentId}};
NSString *url = [NSString stringWithFormat:@"https://www.googleapis.com/youtube/v3/comments?part=snippet&access_token=%@",[[LoginSingleton sharedInstance] getaccesstoken]];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:url]];
[request setHTTPMethod:@"POST"];
[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
NSError *error;
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:parameters
options:0
error:&error];
NSString *jsonString = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];
// And finally, add it to HTTP body and job done.
[request setHTTPBody:[jsonString dataUsingEncoding:NSUTF8StringEncoding]];
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.requestSerializer.timeoutInterval=[[[NSUserDefaults standardUserDefaults] valueForKey:@"timeoutInterval"] longValue];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
AFHTTPRequestOperation *operation = [manager HTTPRequestOperationWithRequest:request progress:nil success:^(NSURLSessionTask *task, id responseObject) {
NSLog(@"Reply JSON: %@", responseObject);
}
} failure:^(NSURLSessionTask *operation, NSError *error) {
NSLog(@"Error: %@, %@, %@, %@, %@", error, operation.responseObject, operation.responseData, operation.responseString, operation.request);
}];
[operation start];
3.0 版的迁移文档将 AFHTTPRequestOperationManager 替换为 AFHTTPSessionManager
但是我似乎找不到 AFHTTPSessionManager.
的 HTTPRequestOperationWithRequest 方法
我尝试使用 constructingBodyWithBlock 但它不起作用，可能是因为我没有正确使用它。
这是我目前无法使用的方法：
NSDictionary *body = @{@"snippet": @{@"topLevelComment":@{@"snippet":@{@"textOriginal":self.commentToPost.text}},@"videoId":self.videoIdPostingOn}};
NSError *error;
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:body
options:0
error:&error];
NSString *jsonString = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
AFJSONRequestSerializer *serializer = [AFJSONRequestSerializer serializer];
serializer.timeoutInterval= [[[NSUserDefaults standardUserDefaults] valueForKey:@"timeoutInterval"] longValue];
[serializer setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[serializer setValue:@"application/json" forHTTPHeaderField:@"Accept"];
[manager POST:[NSString stringWithFormat:@"https://www.googleapis.com/youtube/v3/commentThreads?part=snippet&access_token=%@",[[LoginSingleton sharedInstance] getaccesstoken]] parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> _Nonnull formData) {
[formData appendPartWithHeaders:nil body:[jsonString dataUsingEncoding:NSUTF8StringEncoding]];
} progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
NSLog(@"Reply JSON: %@", responseObject);
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
NSLog(@"Error: %@, %@, %@, %@, %@", error, operation.responseObject, operation.responseData, operation.responseString, operation.request);
}];
我自己解决了这个问题。
这是解决方案。
首先，您需要先从 AFJSONRequestSerializer 创建 NSMutableURLRequest，您可以在其中将方法类型设置为 POST。
根据此请求，您在设置 HTTPHeaderFields 后到达 setHTTPBody。确保在为 content-type 设置 Header 字段后设置 body，否则 api 将给出 400 错误。
然后在管理器上使用上面的 NSMutableURLRequest 创建一个 dataTaskWithRequest。不要忘记在最后 resume dataTask 否则什么也不会发送。这是我的解决方案代码，希望有人能成功使用它：
NSDictionary *body = @{@"snippet": @{@"topLevelComment":@{@"snippet":@{@"textOriginal":self.commentToPost.text}},@"videoId":self.videoIdPostingOn}};
NSError *error;
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:body options:0 error:&error];
NSString *jsonString = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];
AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
NSMutableURLRequest *req = [[AFJSONRequestSerializer serializer] requestWithMethod:@"POST" URLString:[NSString stringWithFormat:@"https://www.googleapis.com/youtube/v3/commentThreads?part=snippet&access_token=%@",[[LoginSingleton sharedInstance] getaccesstoken]] parameters:nil error:nil];
req.timeoutInterval= [[[NSUserDefaults standardUserDefaults] valueForKey:@"timeoutInterval"] longValue];
[req setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[req setValue:@"application/json" forHTTPHeaderField:@"Accept"];
[req setHTTPBody:[jsonString dataUsingEncoding:NSUTF8StringEncoding]];
[[manager dataTaskWithRequest:req completionHandler:^(NSURLResponse * _Nonnull response, id _Nullable responseObject, NSError * _Nullable error) {
if (!error) {
NSLog(@"Reply JSON: %@", responseObject);
if ([responseObject isKindOfClass:[NSDictionary class]]) {
//blah blah
}
} else {
NSLog(@"Error: %@, %@, %@", error, response, responseObject);
}
}] resume];
使用 AFNetworking 3.0 调用 POST 方法的另一种方法是：
AFHTTPSessionManager *manager = [[AFHTTPSessionManager alloc]initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
[manager.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[manager POST:url parameters:parametersDictionary progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
NSLog(@"success!");
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
NSLog(@"error: %@", error);
}];
希望对您有所帮助！
-(void)postRequest:(NSString *)urlStr parameters:(NSDictionary *)parametersDictionary completionHandler:(void (^)(NSString*, NSDictionary*))completionBlock{
NSURL *URL = [NSURL URLWithString:urlStr];
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
[manager POST:URL.absoluteString parameters:parametersDictionary progress:nil success:^(NSURLSessionDataTask *task, id responseObject) {
NSError* error;
NSDictionary* json = [NSJSONSerialization JSONObjectWithData:responseObject
options:kNilOptions
error:&error];
completionBlock(@"Success",json);
} failure:^(NSURLSessionDataTask *task, NSError *error) {
NSLog(@"Error: %@", error);
completionBlock(@"Error",nil);
}];
}
此方法适用于 AFNetworking 3.0。

+ (void)getDataWithObject:(NSDictionary *)object onAPI:(NSString *)apiName withController:(UIViewController*)controller
:(void(^)(BOOL success,id response,NSError *error))compilationHandler {
controller = controller;
[UIApplication sharedApplication].networkActivityIndicatorVisible = YES;
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
// set request type to json
manager.requestSerializer = [AFJSONRequestSerializer serializer];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
// post request to server
[manager POST:apiName parameters:object success:^(AFHTTPRequestOperation *operation, id responseObject) {
// NSError *error;
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:responseObject
options:0
error:&error];
//NSString *JSONString = [[NSString alloc] initWithBytes:[jsonData bytes] length:[jsonData length] encoding:NSUTF8StringEncoding];
////

NSDictionary *dict = responseObject;
NSString *statusOfApi = [[NSString alloc]initWithFormat:@"%@"
,[dict objectForKey:@"OK"]];
// IF Status is OK -> 1 so complete the handler
if ([statusOfApi isEqualToString:@"1"] ) {
[UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
compilationHandler(TRUE,responseObject,nil);
} else {
[UIApplication sharedApplication].networkActivityIndicatorVisible = NO;

}
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {

NSLog(@"Message is %@", message);
NSString *errorMessage = [NSString stringWithFormat:@"%@",[error localizedDescription]];
if (!([message rangeOfString:@"The request timed out."].location == NSNotFound)) {
[Utilities showAlertViewWithTitle:apiName message:errorMessage];
}
compilationHandler(FALSE,errorMessage,nil);
}];
}
对于 HTTPBody 和 JSON
[sessionManager.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[sessionManager.requestSerializer setQueryStringSerializationWithBlock:^NSString *(NSURLRequest *request, id parameters, NSError * __autoreleasing * error) {
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:parameters options:NSJSONWritingPrettyPrinted error:error];
NSString *argString = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];
return argString;
}];
[sessionManager POST:urlString parameters:parameters progress:nil success:^(NSURLSessionDataTask *task, id responseObject) {
if (completion) {
completion(responseObject, nil);
}
} failure:^(NSURLSessionDataTask *task, NSError *error) {
if (completion) {
NSData *errorData = [error.userInfo objectForKey:@"com.alamofire.serialization.response.error.data"];
NSDictionary *responseErrorObject = [NSJSONSerialization JSONObjectWithData:errorData options:NSJSONReadingAllowFragments error:nil];
completion(responseErrorObject, error);
}
}];
对于 HTTPBody 使用自定义字符串格式
[sessionManager.requestSerializer setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
[sessionManager.requestSerializer setQueryStringSerializationWithBlock:^NSString *(NSURLRequest *request, id parameters, NSError * __autoreleasing * error) {
NSString *argString = [self dictionaryToString:parameters];
return argString;
}];
[sessionManager POST:urlString parameters:parameters progress:nil success:^(NSURLSessionDataTask *task, id responseObject) {
if (completion) {
completion(responseObject, nil);
}
} failure:^(NSURLSessionDataTask *task, NSError *error) {
if (completion) {
NSData *errorData = [error.userInfo objectForKey:@"com.alamofire.serialization.response.error.data"];
NSDictionary *responseErrorObject = [NSJSONSerialization JSONObjectWithData:errorData options:NSJSONReadingAllowFragments error:nil];
completion(responseErrorObject, error);
}
}];
使用常见的NSObject Class方法调用Wenservices AFNetworking 3.0
这是我的重复答案，但已 更新为 AFNetworking 3.0
先让NSObjectClass像Webservice.h和Webservice.m
Webservice.h
@interface Webservice : NSObject
+ (void)requestPostUrl:(NSString *)strURL parameters:(NSDictionary *)dictParams success:(void (^)(NSDictionary *responce))success failure:(void (^)(NSError *error))failure;
@end
Webservice.m 你的 nsobject.m 文件看起来像这样。（在 .m 文件中添加两个函数 )
#import "Webservice.h"
#define kDefaultErrorCode 12345
@implementation Webservice
+ (void)requestPostUrl:(NSString *)strURL parameters:(NSDictionary *)dictParams success:(void (^)(NSDictionary *responce))success failure:(void (^)(NSError *error))failure {
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
[manager setResponseSerializer:[AFHTTPResponseSerializer serializer]];
[manager POST:strURL parameters:dictParams progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
if([responseObject isKindOfClass:[NSDictionary class]]) {
if(success) {
success(responseObject);
}
}
else {
NSDictionary *response = [NSJSONSerialization JSONObjectWithData:responseObject options:NSJSONReadingAllowFragments error:nil];
if(success) {
success(response);
}
}
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
if(failure) {
failure(error);
}
}];
}
@end
make sure you have to replace your dictionary key with success and
message for handling of responce callback function
像这样使用 从任何 viewcontroller.m 和任何 viewControllers 调用此通用方法。暂时我使用 viewDidLoad 调用 This WS.
- (void)viewDidLoad {
[super viewDidLoad];
NSDictionary *dictParam = @{@"parameter1":@"value1",@"parameter1":@"value2"};
[Webservice requestPostUrl:@"add your webservice URL here" parameters:dictParam success:^(NSDictionary *responce) {
//Success
NSLog(@"responce:%@",responce);
//do code here
} failure:^(NSError *error) {
//error
}];
}
在上述方法中添加您的参数、值和网络服务 URL。你可以很容易地使用这个 NSObjcet Class。有关详细信息，请访问 AFNetworking 3.0 or my old answear with AFNetworking 2.0.

[sessionManager.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[sessionManager.requestSerializer setQueryStringSerializationWithBlock:^NSString *(NSURLRequest *request, id parameters, NSError * __autoreleasing * error) {
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:parameters options:NSJSONWritingPrettyPrinted error:error];
NSString *argString = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];
return argString;
}];
[sessionManager POST:urlString parameters:parameters progress:nil success:^(NSURLSessionDataTask *task, id responseObject) {
if (completion) {
completion(responseObject, nil);
}
} failure:^(NSURLSessionDataTask *task, NSError *error) {
if (completion) {
NSData *errorData = [error.userInfo objectForKey:@"com.alamofire.serialization.response.error.data"];
NSDictionary *responseErrorObject = [NSJSONSerialization JSONObjectWithData:errorData options:NSJSONReadingAllowFragments error:nil];
completion(responseErrorObject, error);
}
}];
对于 HTTPBody 使用自定义字符串格式
[sessionManager.requestSerializer setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
[sessionManager.requestSerializer setQueryStringSerializationWithBlock:^NSString *(NSURLRequest *request, id parameters, NSError * __autoreleasing * error) {
NSString *argString = [self dictionaryToString:parameters];
return argString;
}];
[sessionManager POST:urlString parameters:parameters progress:nil success:^(NSURLSessionDataTask *task, id responseObject) {
if (completion) {
completion(responseObject, nil);
}
} failure:^(NSURLSessionDataTask *task, NSError *error) {
if (completion) {
NSData *errorData = [error.userInfo objectForKey:@"com.alamofire.serialization.response.error.data"];
NSDictionary *responseErrorObject = [NSJSONSerialization JSONObjectWithData:errorData options:NSJSONReadingAllowFragments error:nil];
completion(responseErrorObject, error);
}
}];
使用常见的NSObject Class方法调用Wenservices AFNetworking 3.0
这是我的重复答案，但已 更新为 AFNetworking 3.0
先让NSObjectClass像Webservice.h和Webservice.m
Webservice.h
@interface Webservice : NSObject
+ (void)requestPostUrl:(NSString *)strURL parameters:(NSDictionary *)dictParams success:(void (^)(NSDictionary *responce))success failure:(void (^)(NSError *error))failure;
@end
Webservice.m 你的 nsobject.m 文件看起来像这样。（在 .m 文件中添加两个函数 )
#import "Webservice.h"
#define kDefaultErrorCode 12345
@implementation Webservice
+ (void)requestPostUrl:(NSString *)strURL parameters:(NSDictionary *)dictParams success:(void (^)(NSDictionary *responce))success failure:(void (^)(NSError *error))failure {
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
[manager setResponseSerializer:[AFHTTPResponseSerializer serializer]];
[manager POST:strURL parameters:dictParams progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
if([responseObject isKindOfClass:[NSDictionary class]]) {
if(success) {
success(responseObject);
}
}
else {
NSDictionary *response = [NSJSONSerialization JSONObjectWithData:responseObject options:NSJSONReadingAllowFragments error:nil];
if(success) {
success(response);
}
}
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
if(failure) {
failure(error);
}
}];
}
@end
make sure you have to replace your dictionary key with success and message for handling of responce callback function
像这样使用 从任何 viewcontroller.m 和任何 viewControllers 调用此通用方法。暂时我使用 viewDidLoad 调用 This WS.
- (void)viewDidLoad {
[super viewDidLoad];
NSDictionary *dictParam = @{@"parameter1":@"value1",@"parameter1":@"value2"};
[Webservice requestPostUrl:@"add your webservice URL here" parameters:dictParam success:^(NSDictionary *responce) {
//Success
NSLog(@"responce:%@",responce);
//do code here
} failure:^(NSError *error) {
//error
}];
}
在上述方法中添加您的参数、值和网络服务 URL。你可以很容易地使用这个 NSObjcet Class。有关详细信息，请访问 AFNetworking 3.0 or my old answear with AFNetworking 2.0.
