AFNetworking 2.0 总是 return 403

Question

我正在使用 AFNetworking 2.0

为 JSON 发出 GET 请求

    self.managerMasterFetchDeletes = [AFHTTPRequestOperationManager manager];
        self.managerMasterFetchDeletes.requestSerializer.timeoutInterval = 4.0f;
        self.managerMasterFetchDeletes.requestSerializer = [AFJSONRequestSerializer serializer];
        self.managerMasterFetchDeletes.responseSerializer = [AFJSONResponseSerializer serializer];

NSURL *URL = [NSURL URLWithString:rest];
    NSURLRequest *request = [NSURLRequest requestWithURL:URL];
    AFHTTPRequestOperation *op = [[AFHTTPRequestOperation alloc] initWithRequest:request];
    op.responseSerializer = [AFJSONResponseSerializer serializer];

    [op setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
        if (operation.response.statusCode==200){

            NSDictionary *dictionary   = (NSDictionary*)responseObject;
            NSMutableDictionary *responseData = [NSMutableDictionary new];
            if ([dictionary objectForKey:@"responseData"]) {
                responseData = [[dictionary objectForKey:@"responseData"] mutableCopy];
            }
            [responseData setValue:entity forKey:@"entityName"];
            [responseData setValue:[NSNumber numberWithInt:timeStamp] forKey:@"lastSync"];
            [[NSNotificationCenter defaultCenter]
             postNotificationName:notification
             object:nil userInfo:responseData];

        }
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        NSLog(@"Error: %@", error);
    }];

 NSArray *operations = [AFURLConnectionOperation batchOfRequestOperations:[arrayOperations copy] progressBlock:^(NSUInteger numberOfFinishedOperations, NSUInteger totalNumberOfOperations) {
        NSLog(@"%lu of %lu fetch delete complete", numberOfFinishedOperations, totalNumberOfOperations);
    } completionBlock:^(NSArray *operations) {
        NSLog(@"All operations in batch complete");
        [[NSNotificationCenter defaultCenter]
         postNotificationName:@"MasterFecthDeleteEnd"
         object:nil
         userInfo:nil];
    }];

    [self.managerMasterFetchDeletes.operationQueue addOperations:operations waitUntilFinished:NO];

但总是 returns 403 错误：不可接受的内容类型：text/html

奇怪的是我用 Cocoa GraphicalHttpClient 做的同样的请求，没关系 returns JSON 响应和这个：

内容类型：application/json；字符集=UTF-8 日期：2015 年 9 月 25 日星期五 15:28:27 GMT 传输编码：身份 X-Powered-By: Servlet/2.5 JSP/2.1

非常感谢。

Answer 1

您的服务器似乎发送了 text/html ContentType。要接受此类内容，请添加 text/html acceptableContentTypes.

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/html"];
[manager GET:url parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {

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

}];

Answer 2

这意味着您的服务器正在发送 "text/html" 而不是已经支持的类型。我的解决方案是将 "text/html" 添加到 AFURLResponseSerialization class 中设置的 acceptableContentTypes。只需搜索 "acceptableContentTypes" 并手动将 @"text/html" 添加到集合中。

op.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/html"];

当然，理想的解决方案是更改从服务器发送的类型，但为此您必须与服务器团队联系。

在你的情况下你可以这样做。

NSURL *URL = [NSURL URLWithString:rest];
    NSURLRequest *request = [NSURLRequest requestWithURL:URL];
    AFHTTPRequestOperation *op = [[AFHTTPRequestOperation alloc] initWithRequest:request];
    op.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/html"];

    [op setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
        if (operation.response.statusCode==200){

            NSDictionary *dictionary   = (NSDictionary*)responseObject;
            NSMutableDictionary *responseData = [NSMutableDictionary new];
            if ([dictionary objectForKey:@"responseData"]) {
                responseData = [[dictionary objectForKey:@"responseData"] mutableCopy];
            }
            [responseData setValue:entity forKey:@"entityName"];
            [responseData setValue:[NSNumber numberWithInt:timeStamp] forKey:@"lastSync"];
            [[NSNotificationCenter defaultCenter]
             postNotificationName:notification
             object:nil userInfo:responseData];

        }
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        NSLog(@"Error: %@", error);
    }];
