最近开始做自己app的服务器，因为正在参与的公司项目用的是springMVC，干脆拿这个做服务器，iOS端采用第三方鼎鼎大名的ASIHTTPRequest（但是已停更很久），经过一天折腾，终于实现简单的图片上传
- 配置ASIHTTPRequest，参见
ASIHTTPRequest配置说明 搭建简单的springMVC环境

代码
iOS端：
-(void)uploadImgToServer:(UIImage*)image{
ASIFormDataRequest *formDataRequest=[ASIFormDataRequest requestWithURL:[NSURL URLWithString:@"http://tyrantkemp.imwork.net:21848/mvc1/helloworld/uploadfile"]];
[formDataRequest setPostValue:@"hahaha" forKey:@"name"];
NSData *postData=UIImageJPEGRepresentation(image, 3);
if(postData==nil){
NSLog(@"pic data为空！！！");
}
[formDataRequest setDelegate:self];
[formDataRequest addData:postData forKey:@"file"];
NSLog(@"pic data:%@",formDataRequest);
[formDataRequest setDidFailSelector:@selector(urlRequestFailed:)];
[formDataRequest setDidFinishSelector:@selector(urlRequestSucceeded:)];
[formDataRequest startSynchronous];
// NSLog(@"responce is %@",[formDataRequest responseString]);
}
//请求失败
-(void)urlRequestFailed:(ASIHTTPRequest *)request
{
NSError *error =[request error];
NSLog(@"%@",error);
NSLog(@"连接失败！");
UIAlertView * alt=[[UIAlertView alloc] initWithTitle:@"提示" message:@"连接服务器失败" delegate:nil cancelButtonTitle:@"确定" otherButtonTitles:nil, nil];
[alt show];
}
//请求成功
-(void)urlRequestSucceeded:(ASIHTTPRequest *)request
{
NSData *data=[request responseData];
NSXMLParser *parser=[[NSXMLParser alloc] initWithData:data];
NSLog(@"data length = %d",[data length]);
NSLog(@"xml data = %@",[[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]);
[parser setDelegate:self];
[parser parse];//进入解析
}springmvc端：
@RequestMapping(value = "/uploadfile", method = RequestMethod.POST)
public String handleFileUpload(@RequestParam("file") CommonsMultipartFile file,HttpServletRequest request) throws FileUploadException{
long startTime=System.currentTimeMillis(); //获取开始时间
if(!file.isEmpty()){
try {
File ouputimage = new File("C:/pic/green2.jpg"); //新建一个文件
try {
file.getFileItem().write(ouputimage); //将上传的文件写入新建的文件中
} catch (Exception e) {
e.printStackTrace();
}
}catch(Exception e){
e.printStackTrace();
}
}
long endTime=System.currentTimeMillis(); //获取结束时间
System.out.println("上传文件共使用时间："+(endTime-startTime));
return "success";
}
