上传使用AFNetworking

NSURL *url = [NSURL URLWithString:@"http://127.0.0.1:8000/photo/"]; AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:url]; NSDictionary *headers = [NSDictionary dictionaryWithObject:data forKey:@"attachment"]; //NSLog(@"strimng"); NSMutableURLRequest *request = [httpClient multipartFormRequestWithMethod:@"POST" path:@"upload/" parameters:nil constructingBodyWithBlock: ^(id<AFMultipartFormData> formData) { NSLog(@"strimng"); [formData appendPartWithFileData:data name:@"attachment" fileName:@"attachment.jpg" mimeType:@"image/jpeg"]; NSLog(@"strimng"); }]; NSLog(@"strimng"); AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request]; [operation setUploadProgressBlock:^(NSUInteger bytesWritten, long long totalBytesWritten, long long totalBytesExpectedToWrite) { NSLog(@"Sent %lld of %lld bytes", totalBytesWritten, totalBytesExpectedToWrite); }]; [operation start]; 

我试图从iphone使用AFNetworking上传图像，但这是行不通的。 在formdata appenddata命令之前的NSLog被注销。 但之后的那个似乎不是。 我也检查了NSdata是否为零，那也不是这种情况。 而obv请求没有被发送。 请任何人都可以帮助我。

假设你必须上传一个图片，为什么你要用data创build一个NSDictionary ？ 这是没有必要的，你只需要使用multipartFormRequestWithMethod内的data 。

尝试以下

 // Get the image that you want to upload via ImagePicker or a @property UIImage *imageIWantToUpload = self.image; // Create the NSData object for the upload process NSData *dataToUpload = UIImageJPEGRepresentation(imageIWantToUpload, 0.5); NSMutableURLRequest *request = [httpClient multipartFormRequestWithMethod:@"POST" path:@"upload/" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) { [formData appendPartWithFileData:dataToUpload name:@"attachment" fileName:@"attachment.jpg" mimeType:@"image/jpg"]; }]; // You can add then the progressBlock and the completionBlock AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request]; [operation setUploadProgressBlock:progress]; [operation setCompletionBlockWithSuccess:success failure:failure]; 

你还应该仔细检查你的服务器端是否需要一些参数，因为你将NSMutableURLRequest参数的字段设置为nil 。
