【问题描述】：

我的 AFNetworking 代码似乎没有将任何图像和文本上传到服务器，但是当我尝试将图像上传到 php 文件时，Json 返回下面列出的错误或错误代码 3840。任何想法都会是如果您需要更多信息，请告诉我。

-(void)upLoadImage
 
   AFHTTPRequestOperationManager *manager = [[AFHTTPRequestOperationManager alloc] initWithBaseURL:[NSURL URLWithString:@"https://***.php"]];

manager.responseSerializer = [AFHTTPResponseSerializer serializer];

NSData *imageData = UIImageJPEGRepresentation(self.imageView.image, 0.5);
NSDictionary *parameters = @@"message": self.pictureMessage.text;
AFHTTPRequestOperation *op = [manager POST:@"rest.of.url" parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) 


    //do not put image inside parameters dictionary as I did, but append it!
    [formData appendPartWithFileData:imageData name:@"userfl" fileName:@"upload.jpg" mimeType:@"image/jpeg"];
 success:^(AFHTTPRequestOperation *operation, id responseObject) 
    NSLog(@"Success: %@ ***** %@", operation.responseString, responseObject);
 failure:^(AFHTTPRequestOperation *operation, NSError *error) 
    NSLog(@"Error: %@ ***** %@", operation.responseString, error);
];


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

PHP：

    <?php

header('Content-type: application/json');

if(!empty($_POST)) 


    $message = $_POST['message'];

    $directory = $_SERVER['DOCUMENT_ROOT'] . '/appphotos';

    $file = basename($_FILES['userfl']['upload.jpg']);

    $uploadfile = $directory . $file;

    echo 'message= '.$message;

    var_dump($_FILES);

    $randomPhotoID = md5(rand() * time());

    echo json_encode($file);

if (move_uploaded_file($_FILES['userfl']['tmp_name'], $uploadfile)) 
    
    $response["success"];
    echo json_encode($response);
    
    else
    
    $response["failure"];
    echo json_encode($response);




else

    $response['Empty post data'];
    echo json_encode($response);


?>

错误：

【问题讨论】：

您能粘贴来自该 JSON 数据的响应吗？您是否设置了适当的标头作为响应？

看起来你的响应不是 json

应该是。你有什么建议吗？

是 - 将 PHP 响应编码为 JSON 数据

我做到了。我在标题中将它设置为 content/json。

【参考方案1】：

试试这个？

manager.requestSerializer = [AFJSONRequestSerializer serializer];
