**我在stackoverflow中查阅了很多关于将图像从iPhone上传到服务器的答案，但仍然没有找到解决方案

这是一个简单的图像上传，附带一个用户ID，下面是我的代码**

NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init] ;

request.timeoutInterval = 60;

[request setURL:[NSURL URLWithString:url]];
[request setHTTPMethod:@"POST"];
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];
[request setValue:@"image/png" forHTTPHeaderField:@"Content-Type"];    
[request setValue:@"07ee7054-010b-44da-a14f-02e3e66800b7" forHTTPHeaderField:@"userId"];
[request imageData];

conn = [[NSURLConnection alloc]
        initWithRequest:request
        delegate:self startImmediately:NO];

[conn scheduleInRunLoop:[NSRunLoop mainRunLoop]
                forMode:NSDefaultRunLoopMode];
[conn start];

if (conn)
{
    receivedData = nil;
    receivedData = [NSMutableData data] ;
    [receivedData setLength:0];
}
这就是我的服务器端的外观

我得到的回应是

有人能帮我渡过难关吗？提前感谢。

您不能同时发送内容类型：图像/png和字符串数据。您需要发送一个请求。您需要设置您的服务器来处理此问题。

错误提示自我回答：@remes，感谢您清楚地编辑我的帖子。我把它告诉了我的服务器端，现在它似乎正在工作。谢谢
