AFNetworking 3.0.4 Error:"Request failed: unacceptable content-type: text/html"

使用AFNetWorking上传内容+参数，

 1 NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:@"http://example.com/upload" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
 2         [formData appendPartWithFileURL:[NSURL fileURLWithPath:@"file://path/to/image.jpg"] name:@"file" fileName:@"filename.jpg" mimeType:@"image/jpeg" error:nil];
 3     } error:nil];
 4
 5 AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
 6
 7 NSURLSessionUploadTask *uploadTask;
 8 uploadTask = [manager
 9               uploadTaskWithStreamedRequest:request
10               progress:^(NSProgress * _Nonnull uploadProgress) {
11                   // This is not called back on the main queue.
12                   // You are responsible for dispatching to the main queue for UI updates
13                   dispatch_async(dispatch_get_main_queue(), ^{
14                       //Update the progress view
15                       [progressView setProgress:uploadProgress.fractionCompleted];
16                   });
17               }
18               completionHandler:^(NSURLResponse * _Nonnull response, id  _Nullable responseObject, NSError * _Nullable error) {
19                   if (error) {
20                       NSLog(@"Error: %@", error);
21                   } else {
22                       NSLog(@"%@ %@", response, responseObject);
23                   }
24               }];
25
26 [uploadTask resume];

上传成功，但是返回错误信息：

之前遇到过，又跳进了老坑，答案在这里。

只需要在AFURLResponseSerialization.m的acceptableContentTypes中，添加text/html类型。

 1 ...
 2
 3 - (instancetype)init {
 4     self = [super init];
 5     if (!self) {
 6         return nil;
 7     }
 8
 9     self.acceptableContentTypes = [NSSet setWithObjects:@"application/json", @"text/json", @"text/javascript",@"text/html", nil];
10
11     return self;
12 }
13
14 ....
