AFNetworking的用法

AFNeiworking 用法

1、get post请求

    NSString *url1 = @"http://api.openweathermap.org/data/2.5/forecast/daily?lat=39.907501&lon=116.397232&cnt=10";//测试get请求

    

    NSString *url2 =@"http://webservice.webxml.com.cn/WebServices/MobileCodeWS.asmx/getMobileCodeInfo";//测试post请求

    

    //创建一个请求管理类对象

    AFHTTPRequestOperationManager* manager = [AFHTTPRequestOperationManager manager];

    manager.responseSerializer.acceptableContentTypes = [manager.responseSerializer. acceptableContentTypes setByAddingObject:@"text/html"];

    

    //设置请求类型

    manager.requestSerializer = [AFHTTPRequestSerializer serializer];

    

    //设置返回类型 json AFXMLParserResponseSerializer:xml类型 AFHTTPResponseSerializer:二进制类型

    //manager.responseSerializer = [AFJSONResponseSerializer serializer];

    manager.responseSerializer = [AFXMLParserResponseSerializer serializer];

    

    //get请求

    [manager GET:url1parameters:nil success:^(AFHTTPRequestOperation *operation,id responseObject) {

        NSLog(@"%@",responseObject);

        

    } failure:^(AFHTTPRequestOperation *operation,NSError *error) {

        NSLog(@"%@",error);

    }];

    

    //post请求，参数不显示在正文（一个网址？后面就是正文，内容就是参数），参数设置在parameters里

    [manager POST:url2parameters:@{@"mobileCode":@"15910514636",@"userID":@""}success:^(AFHTTPRequestOperation *operation,id responseObject) {

        NSLog(@"%@",responseObject);

        

    } failure:^(AFHTTPRequestOperation *operation,NSError *error) {

        NSLog(@"%@",error);

        

    }];

2、上传

NSString* url = @"";

    //参数

    NSDictionary* paras =@{};

    //获得的数据

    NSDate* data =nil;

    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];

    manager.requestSerializer = [AFHTTPRequestSerializer serializer];

    manager.responseSerializer = [AFJSONResponseSerializer serializer];

    

    manager.responseSerializer.acceptableContentTypes = [manager.responseSerializer.acceptableContentTypes   setByAddingObject:@"text/html"];

    AFHTTPRequestOperation *httpoperation = [managerPOST:urlparameters:paras constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {//构造数据，上传的数据

        [formData appendPartWithFileData:dataname:@"upload"fileName:@"image1.jpg"mimeType:nil];

        

    } success:^(AFHTTPRequestOperation *operation,id responseObject) {

        

    } failure:^(AFHTTPRequestOperation *operation,NSError *error) {

        

    }];

3、监听网络状态

//开启网络状态指示器

    [[AFNetworkActivityIndicatorManager sharedManager]setEnabled:YES];

    //初始化监听

    AFHTTPRequestOperationManager* manager =  [[AFHTTPRequestOperationManager alloc]initWithBaseURL:[NSURL URLWithString:@"http://www.baidu.com"]];

    NSOperationQueue* queue = manager.operationQueue;

    

    //监听结果回调

    [manager.reachabilityManager setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {

        switch (status) {

            caseAFNetworkReachabilityStatusReachableViaWiFi:

            caseAFNetworkReachabilityStatusReachableViaWWAN:

                [queue setSuspended:NO];//设置是否挂起该进程

                NSLog(@"have net");

                break;

            caseAFNetworkReachabilityStatusNotReachable:

            default:

                [queue setSuspended:YES];

                NSLog(@"no");

                break;

        }

    }];

    //开始监听

    [manager.reachabilityManager startMonitoring];
