使用AFJSONRequestOperation和filedata的AFNetworking永远不会完成
我正在使用AFNetworking将json数据发布到我的web服务并获得一个json响应。 不过现在我也想把多部分formdata添加到这些POST中。 如果我这样做（即使没有我首先添加的参数）完成块永远不会触发。 进度块确实会触发，我可以看到文件正确上传。
有没有人有任何经验张贴AFNetworking像这样的图像？ 我正在使用最新的AFNetworking来源/版本。
这是我的初始代码发布与json在其中的字典。 这工作正常。
NSMutableDictionary *postdata = [[NSMutableDictionary alloc] init]; [postdata setObject:[postdictionary JSONString] forKey:@"request"]; NSMutableURLRequest *jsonRequest = [httpClient requestWithMethod:@"POST" path:path parameters:postdata]; AFJSONRequestOperation *operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:jsonRequest success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON) {// Success} failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, id JSON) {// Failure }]; [operation start]; 这是提交图像的代码版本（不起作用）
NSMutableURLRequest *jsonRequest jsonRequest = [httpClient multipartFormRequestWithMethod:@"POST" path:path parameters:postdata constructingBodyWithBlock: ^(id <AFMultipartFormData> formData) { [formData appendPartWithFileData:imageData name:@"photo" fileName:@"photo.jpg" mimeType:@"image/jpeg"]; [formData throttleBandwidthWithPacketSize:5000 delay:0.1]; }]; AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:jsonRequest]; [operation setUploadProgressBlock:^(NSUInteger bytesWritten, long long totalBytesWritten, long long totalBytesExpectedToWrite) { NSLog(@"Sent %lld of %lld bytes", totalBytesWritten, totalBytesExpectedToWrite); }]; [operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) { NSLog(@"Upload succes"); } failure:^(AFHTTPRequestOperation *operation, NSError *error) { NSLog(@"Upload failed"); }]; [operation start];
我在一些应用程序上使用这个代码，并没有任何问题（注意我正在使用AFJSONRequestOperation和AFRestClient）
设置请求
// I have a shared singleton in a separate file APIClient.h AFRESTClient *httpClient = [APIClient sharedClient]; NSURLRequest *request = [httpClient multipartFormRequestWithMethod:@"POST" path:method parameters:params constructingBodyWithBlock: ^(id <AFMultipartFormData> formData) {[formData appendPartWithFileData:imageData name:@"image" fileName:@"image.png" mimeType:@"image/png"]; }];
那么操作，
AFJSONRequestOperation *operation = [[AFJSONRequestOperation alloc] initWithRequest:request];
我的进度块
[operation setUploadProgressBlock:^(NSUInteger bytesWritten, long long totalBytesWritten, long long totalBytesExpectedToWrite) { NSLog(@"Sent %lld of %lld bytes", totalBytesWritten, totalBytesExpectedToWrite); CGFloat progress = ((CGFloat)totalBytesWritten) / totalBytesExpectedToWrite * 100; [SVProgressHUD showProgress:50 status:[NSString stringWithFormat:@"%0.1f %%", progress]]; }];
成功块（我的API返回一个stat -ok或失败，然后数据（与flickr API相同）
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id response) { NSLog(@"response string: %@", operation.responseString); NSString *resultStat = [response objectForKey:@"stat"]; if ([resultStat isEqualToString:@"ok"]) { //success // do something with your data that is returned from the API } else { //error NSLog(@"Data Error: %@", response); } } failure:^(AFHTTPRequestOperation *operation, NSError *error) { NSLog(@"Error: %@", [error localizedDescription]); }]; [httpClient enqueueHTTPRequestOperation:operation];
无法看到您的代码的任何问题，几乎没有可能性：
尝试设置短超时间隔，并检查请求是否完成[request setTimeoutInterval：5];
也尝试注释节stream线，看看它是否改变任何东西
