【问题描述】:
**我在 stackoverflow 中查看了很多关于将图像从 iPhone 上传到服务器的答案,但仍然无法找到解决方案。
这是一个带有 UserID 的简单图片上传,这是我的代码的外观**
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样子,
@RequestMapping(value = "/uploadphoto", method = RequestMethod.POST, headers="Accept = */*")
public Map<String,Object> uploadPhoto(InputStream in,@RequestBody String JSONContentofPOST)
{
return UploadPhoto(in,JSONContentofPOST);
}
我得到的回应是
<html>
<head>
<title>Apache Tomcat/7.0.53 - Error report</title>

<p><b>description</b> <u>The request sent by the client was syntactically incorrect.</u></p>
有人可以帮我解决这个问题吗?提前致谢。
