/**
监听ASI的请求
1.成为代理，遵守ASIHTTPRequestDelegate协议，实现协议中的代理方法
request.delegate = self;
- (void)requestStarted:(ASIHTTPRequest *)request;
- (void)request:(ASIHTTPRequest *)request didReceiveResponseHeaders:(NSDictionary *)responseHeaders;
- (void)request:(ASIHTTPRequest *)request didReceiveData:(NSData *)data;
- (void)requestFinished:(ASIHTTPRequest *)request;
- (void)requestFailed:(ASIHTTPRequest *)request;
2.成为代理，不遵守ASIHTTPRequestDelegate协议，自定义代理方法
request.delegate = self;
[request setDidStartSelector:@selector(start:)];
[request setDidFinishSelector:@selector(finish:)];
3.设置block
[request setStartedBlock:^{
NSLog(@"setStartedBlock");
}];
[request setHeadersReceivedBlock:^(NSDictionary *responseHeaders) {
NSLog(@"setHeadersReceivedBlock--%@", responseHeaders);
}];
[request setDataReceivedBlock:^(NSData *data) {
NSLog(@"setDataReceivedBlock--%@", data);
}];
[request setCompletionBlock:^{
NSLog(@"setCompletionBlock");
}];
[request setFailedBlock:^{
NSLog(@"setFailedBlock");
}];

//ASI文件上传
-(void)upload{
//1、URL
NSURL *url = [NSURL URLWithString:@"http://localhost:8080/MJServer/upload"];

//3、设置请求参数

//方式一：如果知道文件路径最好使用这个方式（简单），ASI内部会自动识别文件的MIMType

//方式二：(一般不用)

//方式三：如果文件是动态产生的，就用这个方法（比如刚拍完照获得的图片数据）
