一、GET和POST请求数据

//GET请求
- (IBAction)get:(id)sender {
    //1.创建管理对象
    AFHTTPSessionManager*manager = [AFHTTPSessionManagermanager];

    //2.URL
    NSString*url =@"http://piao.163.com/m/cinema/list.html?app_id=1&mobileType=iPhone&ver=2.6&channel=appstore&deviceId=9E89CB6D-A62F-438C-8010-19278D46A8A6&apiVer=6&city=110000";

     //3.设置请求参数类型
     /*
             &拼接：AFHTTPRequestSerializer:key1=value1&key2=value2
             JSON数据：AFJSONRequestSerializer
           */
    manager.requestSerializer= [AFHTTPRequestSerializerserializer];

    //4.设置响应数据类型
    /*
              AFJSONResponseSerializer:返回的数据是JSON格式，默认就是JSON格式
              AFXMLParserResponseSerializer:返回的数据是XML格式
              AFHTTPResponseSerializer：不解析
             AFImageResponseSerializer：图片数据
         */
    manager.responseSerializer= [AFJSONResponseSerializerserializer];

    //5.发送请求
    [manager GET:urlparameters:nilsuccess:^(NSURLSessionDataTask*task,id responseObject) {

        self.testView.text= [NSStringstringWithFormat:@"%@", responseObject];

    } failure:^(NSURLSessionDataTask*task,NSError *error) {
        NSLog(@"%@", error);
    }];

}

----------------------------------------------------------------------------------------------------

//POST请求
- (IBAction)post:(id)sender {

    //1.创建管理对象
    AFHTTPSessionManager*manager = [AFHTTPSessionManagermanager];

    //2.字符串URL
    NSString*url =@"http://piao.163.com/m/movie/detail.html?app_id=1&mobileType=iPhone&ver=2.6&channel=appstore&deviceId=9E89CB6D-A62F-438C-8010-19278D46A8A6&apiVer=6&city=110000";

    //3.设置请求类型
    manager.requestSerializer= [AFHTTPRequestSerializerserializer];

    //4.设置响应数据类型
    manager.responseSerializer= [AFJSONResponseSerializerserializer];

    //5.发送请求
    //设置请求体
    NSDictionary*dict =@{
                           @"movie_id":@"43485"
                           };
    [manager POST:urlparameters:dictsuccess:^(NSURLSessionDataTask*task,id responseObject) {

        self.testView.text= [NSStringstringWithFormat:@"%@", responseObject];

    } failure:^(NSURLSessionDataTask*task,NSError *error) {
        NSLog(@"%@", error);
    }];

}

二、下载

//下载
- (IBAction)downLoad:(id)sender {

//    1.创建URL对象
    NSURL *url = [NSURLURLWithString:@"http://sc.111ttt.com/up/mp3/304296/937161E63A1D57484158C7464D7B50B7.mp3"];

//    2.创建请求对象
    NSMutableURLRequest*request = [NSMutableURLRequestrequestWithURL:url];

//    3.创建管理对象
    AFHTTPSessionManager*manager = [AFHTTPSessionManagermanager];

//    4.创建请求任务

----------------------------------------------------------------------------------------------------

//    （1）声明进度变量
    NSProgress*progress =nil;

//    （2）请求任务
    NSURLSessionDownloadTask*task = [managerdownloadTaskWithRequest:requestprogress:&progressdestination:^NSURL*(NSURL*targetPath,NSURLResponse *response) {

//        动态获取Document目录
        NSString*doc = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask,YES)lastObject];

//        返回我们要放到的路径

return [NSURL fileURLWithPath:[NSStringstringWithFormat:@"%@music.mp3", doc]];

    } completionHandler:^(NSURLResponse*response,NSURL *filePath, NSError*error) {

        NSLog(@"%@", filePath);

    }];

----------------------------------------------------------------------------------------------------

//    5.开始任务
    [task resume];

//    6.给progress添加监听观察新值变化
    [progress addObserver:selfforKeyPath:NSStringFromSelector(@selector(fractionCompleted))options:NSKeyValueObservingOptionNewcontext:nil];

}

// 7.触发监听事件
- (void)observeValueForKeyPath:(NSString*)keyPath ofObject:(id)object change:(NSDictionary*)change context:(void*)context
{
//    取出字典里变化的新值
    NSNumber*new = change[@"new"];
    CGFloat value = [new floatValue];

//    回主队列刷新UI
    dispatch_async(dispatch_get_main_queue(), ^{
        self.progress.progress= value;
    });

}
