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 = [manager
downloadTaskWithRequest:request
progress:&progress
destination:^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;

    });

   
}
