【问题描述】：

如何获得 JSON 响应？如果 php 打印一些 JSON 整个请求失败，如果 PHP 不打印任何内容，则响应成功。如何使用 AFHTTPRequestOperation ？

 AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
        NSDictionary *parameters = @@"foo":@"barr";
        UIImage *image = myImage.image;
        [manager POST:@"http://local/index.php"
           parameters:parameters
    constructingBodyWithBlock:^(id<AFMultipartFormData> formData)
        [formData appendPartWithFileData:UIImageJPEGRepresentation(image, 0.7)
                                    name:@"file"
                                fileName:@"photo.jpg"
                                mimeType:@"image/jpeg"];
    
              success:^(AFHTTPRequestOperation *operation, id responseObject)
                  NSLog(@"Success: %@", responseObject);
              
              failure:^(AFHTTPRequestOperation *operation, NSError *error)
                  NSLog(@"Error %@", operation.responseString);
              ];

【参考方案1】：

在成功块中尝试：

NSError *e;
NSDictionary *jsonDict = [NSJSONSerialization JSONObjectWithData:[operation.responseString dataUsingEncoding:NSUTF8StringEncoding] options:NSJSONReadingMutableContainers error:&e];
