使用AFNetworking 3.0上传图像

我试图用AFNetworking3.0上传图片。 我试图find如何从所有的stackoverflow和教程上传图像，但所有这些都与AFNetworking2.0及以下相关。 主要的重点是我要上传图像到网站。

一旦图像上传，图像的url应该存在网站上。

请参阅下面的代码。

AFHTTPRequestOperationManager *requestManager; [requestManager POST:KAPIUploadOutfit parameters:params constructingBodyWithBlock:^(id<AFMultipartFormData> formData) { [formData appendPartWithFileURL:fileURL name:@"photo_url" fileName:filename mimeType:@"image/png" error:nil]; } success:^(AFHTTPRequestOperation *operation, id responseObject) { successCB(responseObject); } failure:^(AFHTTPRequestOperation *operation, NSError *error) { errorCB(CONNECTION_ERROR); }]; 

我不确定参数是关于什么的。 请告诉我如何做到这一点。

 NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:@"http://example.com/upload" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) { [formData appendPartWithFileURL:[NSURL fileURLWithPath:@"file://path/to/image.jpg"] name:@"file" fileName:@"filename.jpg" mimeType:@"image/jpeg" error:nil]; } error:nil]; AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]]; NSURLSessionUploadTask *uploadTask; uploadTask = [manager uploadTaskWithStreamedRequest:request progress:^(NSProgress * _Nonnull uploadProgress) { // This is not called back on the main queue. // You are responsible for dispatching to the main queue for UI updates dispatch_async(dispatch_get_main_queue(), ^{ //Update the progress view [progressView setProgress:uploadProgress.fractionCompleted]; }); } completionHandler:^(NSURLResponse * _Nonnull response, id _Nullable responseObject, NSError * _Nullable error) { if (error) { NSLog(@"Error: %@", error); } else { NSLog(@"%@ %@", response, responseObject); } }]; [uploadTask resume]; 

在这个代码中， http://example.com/upload是图片要上传的api， file：//path/to/image.jpg是你的本地图片path。

在AFNetworking 3.0上传任务是这样工作的。

  NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:@"http://example.com/upload" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) { [formData appendPartWithFileURL:[NSURL fileURLWithPath:@"file://path/to/image.jpg"] name:@"file" fileName:@"filename.jpg" mimeType:@"image/jpeg" error:nil]; } error:nil]; AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]]; NSURLSessionUploadTask *uploadTask; uploadTask = [manager uploadTaskWithStreamedRequest:request progress:^(NSProgress * _Nonnull uploadProgress) { // This is not called back on the main queue. // You are responsible for dispatching to the main queue for UI updates dispatch_async(dispatch_get_main_queue(), ^{ //Update the progress view [progressView setProgress:uploadProgress.fractionCompleted]; }); } completionHandler:^(NSURLResponse * _Nonnull response, id _Nullable responseObject, NSError * _Nullable error) { if (error) { NSLog(@"Error: %@", error); } else { NSLog(@"%@ %@", response, responseObject); } }]; [uploadTask resume];
