AFNetworking 3.0 中带有图像和其他参数的多部分数据

Question

使用其他参数上传图片时出现问题。使用 AFNetworking 3.0

com.alamofire.serialization.response.error.data=<7b227374 61747573 223a2246 41494c55 5245222c 22737461 74757343 6f646522 3a353030 7d>, NSLocalizedDescription=请求失败：内部服务器错误 (500)} 我得到[=11]

NSMutableDictionary *getUpdates= [[NSMutableDictionary alloc]init];
NSString*userID=@"3";
[getUpdates setObject:userID forKey:@"userId"];
[getUpdates setObject:phoneNumTF.text forKey:@"mobileNumber"];
[getUpdates setObject:nameTF.text forKey:@"name"];
[getUpdates setObject:workZipCodeTF.text forKey:@"work"];
[getUpdates setObject:homeZipCodeTF.text forKey:@"home"];

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];

[manager POST:kUpdateProfile_Post parameters:getUpdates constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
    [formData appendPartWithFileData:ImageData
                                name:@"files"
                            fileName:@"picture" mimeType:@"image/jpeg"];
} progress:nil success:^(NSURLSessionDataTask *task, id responseObject) {
    NSLog(@"Response: %@", responseObject);
} failure:^(NSURLSessionDataTask *task, NSError *error) {
    NSLog(@"Error: %@", error);
}];

这里我需要发送这样的数据 picture:filename json:{ "name": "harish", "work": 92121, "userId": 3, "mobileNumber": 33663366, "home": " 500025" }

有什么帮助吗？

Answer 1

两种可能，

可能是您发送的参数名称不同
服务器开发人员在后端做错了事

和他讨论这个问题，让他在你提出请求时调试每一行。

Answer 2

使用您的代码检查以下内容：

1) 确保 ImageData 不应该是 nil.

2) 检查矿机类型与你的服务器矿机类型。可能两者不同。

3) 使用您的 api 名称检查密钥名称。

Answer 3

// 包含 post 个参数的字典。您可以设置服务器接受或编程接受的 post 参数。

NSUserDefaults *def = [NSUserDefaults standardUserDefaults];
NSString*userID = [def objectForKey:@"UserId"];
NSMutableDictionary *getUpdates= [[NSMutableDictionary alloc]init];
[getUpdates setObject:userID forKey:@"userId"];
[getUpdates setObject:phoneNumTF.text forKey:@"mobileNumber"];
[getUpdates setObject:nameTF.text forKey:@"name"];
[getUpdates setObject:workZipCodeTF.text forKey:@"work"];
[getUpdates setObject:homeZipCodeTF.text forKey:@"home"];


[MBProgressHUD showHUDAddedTo:self.view animated:true];

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
manager.responseSerializer = [AFHTTPResponseSerializer serializer]; // only needed if the server is not returning JSON; if web service returns JSON, remove this line


[manager POST:kUpdateProfile_Post parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
    NSError *error;
    NSData *jsonData = [NSJSONSerialization dataWithJSONObject:getUpdates options:0 error:&error];
    NSAssert(jsonData, @"Failure building JSON: %@", error);


    NSDictionary *jsonHeaders = @{@"Content-Disposition" : @"form-data; name=\"json\"",
                                  @"Content-Type"        : @"application/json"};
    [formData appendPartWithHeaders:jsonHeaders body:jsonData];

    if (ImageData) {
        [formData appendPartWithFileData:ImageData name:@"picture"
                                fileName:@"image.jpg"
                                mimeType:@"image/jpeg"];
    }
} progress:nil success:^(NSURLSessionDataTask *task, id responseObject) {
    NSLog(@"Response: %@", responseObject);

    NSError* error;
    NSDictionary* json = [NSJSONSerialization JSONObjectWithData:responseObject
                                                         options:kNilOptions
                                                           error:&error];
    NSLog(@"error appending part: %@", json);

    [MBProgressHUD hideHUDForView:self.view animated:true];

    [self.navigationController popViewControllerAnimated:YES];

} failure:^(NSURLSessionDataTask *task, NSError *error) {
    NSLog(@"Error: %@", error);
    [MBProgressHUD hideHUDForView:self.view animated:true];

}];

我终于得到了这段代码
