ASI请求数据有get请求和post请求

1 首先导入类库

2 引入包ASIHTTPRequest

3 在 .m文件中

UIButton *getButton = [UIButton buttonWithType:UIButtonTypeCustom];
    [getButton setTitle:@"ASI get请求" forState:UIControlStateNormal];
    getButton.backgroundColor = [UIColor redColor];
    getButton.frame = CGRectMake(20, 100, 150, 40);
    [getButton addTarget:self action:@selector(asiGetRequest) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:getButton];



    UIButton *postButton = [UIButton buttonWithType:UIButtonTypeCustom];
    [postButton setTitle:@"ASI post请求" forState:UIControlStateNormal];
    postButton.backgroundColor = [UIColor redColor];
    postButton.frame = CGRectMake(200, 100, 150, 40);
    [postButton addTarget:self action:@selector(asiPostRequest) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:postButton];

协议方法

#pragma mark --使用asi进行get请求方法一
-(void)asiGetRequest
{
    //1.创建网络请求（GET）
        NSURL *url=[NSURL URLWithString:@"http://project.lanou3g.com/teacher/yihuiyun/lanouproject/activitylist.php"];
        self.request=[ASIHTTPRequest requestWithURL:url];
         //设置网络请求的延时为10秒钟
         self.request.timeOutSeconds=10;

         //2.设置代理
         self.request.delegate=self;


         //3.发送请求(异步请求)
         [self.request startAsynchronous];
}

#pragma mark --发送post请求
-(void)asiPostRequest
{


     //1.创建网络请求（POST）
         NSURL *url=[NSURL URLWithString:@"http://ipad-bjwb.bjd.com.cn/DigitalPublication/publish/Handler/APINewsList.ashx"];
         ASIFormDataRequest *request=[ASIFormDataRequest requestWithURL:url];

         //2.添加请求参数（请求体中得参数）
         [request setPostValue:@"20131129" forKey:@"date"];
         [request setPostValue:@"5" forKey:@"startRecord"];
         [request setPostValue:@"5" forKey:@"len"];
         [request setPostValue:@"1234567890" forKey:@"udid"];
         [request setPostValue:@"Iphone" forKey:@"terminalType"];
         [request setPostValue:@"215" forKey:@"cid"];


          request.delegate = self;
          //3.发送请求
          [request startAsynchronous];

}

#pragma mark- 异步请求的代理方法
//请求开始的时候调用
-(void)requestStarted:(ASIHTTPRequest *)request
{
    self.myData = [NSMutableData data];
}
//接收到服务器返回的数据时调用（数据量比较大的时候，这个方法会被调用多次，每次只能拿到部分数据）
-(void)request:(ASIHTTPRequest *)request didReceiveData:(NSData *)data
{
    [self.myData appendData:data];

}
//请求结束的时候调用（在该方法中拿到最终的数据）
-(void)requestFinished:(ASIHTTPRequest *)request
{
    //将服务器返回的data型数据解析成大字典
    NSMutableDictionary *dic = [NSJSONSerialization JSONObjectWithData:self.myData options:NSJSONReadingMutableContainers error:nil];
    NSLog(@"dic = %@", dic);

}
//发送网络请求失败的时候调用
-(void)requestFailed:(ASIHTTPRequest *)request
{
     NSLog(@"请求失败");
}
