调试AFNetworking

Question

以下代码块用于将图像文件提交到数据库.它已停止工作:即使打印SUCCESS,服务器上也看不到任何图像.关于如何调试这个的任何建议？

我在调试器中打印了imageData并得到了一个内存地址数组,所以我几乎可以肯定我有一个图像.

- (void)postActivityImage:(Spot*)localSpot
{
    NSLog(@"%s",__func__);
    NSString *url = [NSString stringWithFormat:@"v1/activity/%@/image", localSpot.uniqueID];
    UIImage *image = [UIImage imageWithContentsOfFile:localSpot.imageLocalURL];
    NSData *imageData = UIImageJPEGRepresentation(image, 0.5f);
    NSURLRequest *request = [httpClient_ multipartFormRequestWithMethod:@"POST"
                                                                   path:url 
                                                             parameters:nil 
                                              constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
                                                  [formData appendPartWithFileData:imageData 
                                                                              name:@"test" 
                                                                          fileName:@"test" 
                                                                          mimeType:@"image/jpeg"];
                                              }];

    AFJSONRequestOperation *ro;
    ro = [AFJSONRequestOperation JSONRequestOperationWithRequest:request
                                                         success:^(NSURLRequest *request, NSURLResponse *response, id JSON) {
                                                             NSLog(@"success: %@", JSON);
                                                             NSLog(@"SUCCESS - IMAGE POSTED.");
                                                             [self updateSpotSubmitInProgressStatusWithActivityFinished:ImagePost andSuccess:YES];
                                                             [[NSNotificationCenter defaultCenter] postNotificationName:SUBMIT_STATUS object:self userInfo:nil];
                                                             self.spot.imageSubmitted = YES;
                                                         } failure:^(NSURLRequest *request, NSURLResponse *response, NSError *error, id JSON) {
                                                             [self updateSpotSubmitInProgressStatusWithActivityFinished:ImagePost andSuccess:NO];
                                                             NSDictionary *dic = [[NSDictionary alloc] initWithObjectsAndKeys:error, @"Error", nil];
                                                             [[NSNotificationCenter defaultCenter] postNotificationName:SUBMIT_STATUS object:self userInfo:dic];
                                                             NSLog(@"%s   ERROR: %@", __func__, error);
                                                             NSLog(@"%s   RESPONSE: %@",__func__, response);
                                                             NSLog(@"%s   FAIL   json response: %@",__func__, JSON);
                                                         }];

    [httpClient_ enqueueHTTPRequestOperation:ro];
}

调试HTTP连接时,我的首选工具是Charles.您可以在桌面计算机上设置Charles,将其配置为iPhone上的代理,然后观察iPhone生成的HTTP流量.然后,您可以查看是否正在进行请求,如果是,则深入检查每个请求.

以下是设置Charles查看iPhone HTTP流量的一些很好的说明:http://blog.mediarain.com/2009/08/iphone-http-connection-debugging/
