/**
 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");
 }];
