}监听ASI的block请求
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");
}];- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
}
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
// 1.URL
NSURL *url = [NSURL URLWithString:@"http://localhost:8080/MJServer/video"];
// 2.创建一个请求对象
ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
// 3.开始请求
[request startAsynchronous];
// 4.设置监听方法
request.delegate = self;
[request setDidStartSelector:@selector(start:)];
[request setDidFinishSelector:@selector(finish:)];
}
- (void)start:(ASIHTTPRequest *)request
{

}
- (void)asyncBlock
{
// 1.URL
NSURL *url = [NSURL URLWithString:@"http://localhost:8080/Server/video"];
// 2.创建一个请求对象
ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
// 如果同时设置了block和实现了代理方法，请求过程中，block和代理方法都会调用，
// 一般的调用顺序：代理方法 > block
