与AFNetworking一起发送图像和其他参数

我正在更新与AFNetworking一起使用ASIHTTPRequest的旧应用程序代码。 就我而言，我正在向API发送数据，这些数据是不同的types：Image和其他。

下面是我目前采用的代码，实现一个API客户端，请求共享实例，准备params字典并将其发送到远程API：

 NSMutableDictionary *params = [NSMutableDictionary dictionary]; [params setValue:@"Some value" forKey:aKey]; [[APIClient sharedInstance] postPath:@"/post" parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) { //some logic } failure:^(AFHTTPRequestOperation *operation, NSError *error) { //handle error }]; 

当我想要添加一个图像到params字典会是什么情况？

有了ASIHTTPRequest ，我曾经做了以下工作：

 NSData *imgData = UIImagePNGRepresentation(anImage); NSString *newStr = [anImageName stringByReplacingOccurrencesOfString:@"/" withString:@"_"]; [request addData:imgData withFileName:[NSString stringWithFormat:@"%@.png",newStr] andContentType:@"image/png" forKey:anOtherKey]; 

我深入到AFNetworking文档，发现他们在一个NSMutableRequest像这样附加图像：

 AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:url]; NSData *imageData = UIImageJPEGRepresentation([UIImage imageNamed:@"avatar.jpg"], 0.5); NSMutableURLRequest *request = [httpClient multipartFormRequestWithMethod:@"POST" path:@"/upload" parameters:nil constructingBodyWithBlock: ^(id <AFMultipartFormData>formData) { [formData appendPartWithFileData:imageData name:@"avatar" fileName:@"avatar.jpg" mimeType:@"image/jpeg"]; }]; 

我应该如何将这些图像数据整合到APIClient请求中？ 提前感谢。

我已经使用相同的AFNetworking与一些参数上传图像。 这段代码适合我。 可能会有所帮助

 NSData *imageToUpload = UIImageJPEGRepresentation(uploadedImgView.image, 1.0);//(uploadedImgView.image); if (imageToUpload) { NSDictionary *parameters = [NSDictionary dictionaryWithObjectsAndKeys:keyParameter, @"keyName", nil]; AFHTTPClient *client= [AFHTTPClient clientWithBaseURL:[NSURL URLWithString:@"http://------"]]; NSMutableURLRequest *request = [client multipartFormRequestWithMethod:@"POST" path:@"API name as you have" parameters:parameters constructingBodyWithBlock: ^(id <AFMultipartFormData>formData) { [formData appendPartWithFileData: imageToUpload name:@"image" fileName:@"temp.jpeg" mimeType:@"image/jpeg"]; }]; AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request]; [operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) { NSDictionary *jsons = [NSJSONSerialization JSONObjectWithData:responseObject options:kNilOptions error:nil]; //NSLog(@"response: %@",jsons); } failure:^(AFHTTPRequestOperation *operation, NSError *error) { if([operation.response statusCode] == 403) { //NSLog(@"Upload Failed"); return; } //NSLog(@"error: %@", [operation error]); }]; [operation start]; } 

祝你好运 ！！

随着AFNetworking 2.0.1这个代码为我工作。

 -(void) saveImage: (NSData *)imageData forImageName: (NSString *) imageName { AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager]; NSString *imagePostUrl = [NSString stringWithFormat:@"%@/v1/image", BASE_URL]; NSDictionary *parameters = @{@"imageName": imageName}; NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:imagePostUrl parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) { [formData appendPartWithFileData:imageData name:@"image" fileName:imageName mimeType:@"image/jpeg"]; }]; AFHTTPRequestOperation *op = [manager HTTPRequestOperationWithRequest:request success: ^(AFHTTPRequestOperation *operation, id responseObject) { DLog(@"response: %@", responseObject); } failure:^(AFHTTPRequestOperation *operation, NSError *error) { DLog(@"Error: %@", error); }]; op.responseSerializer = [AFHTTPResponseSerializer serializer]; [[NSOperationQueue mainQueue] addOperation:op]; } 

如果需要JSON响应，请使用：

 op.responseSerializer = [AFJSONResponseSerializer serializer]; 

代替

 op.responseSerializer = [AFHTTPResponseSerializer serializer];
