iOS开发之AFNetworking 3.0.4使用-OC

 

---

GET请求

 AFHTTPSessionManager *manager = [AFHTTPSessionManager manager]; 

 [manager GET:URL parameters:nil progress:^(NSProgress * _Nonnull downloadProgress) {  

 }
  success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {  

  NSLog(@"这里打印请求成功要做的事");  

 }

 failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull   error) {  

 NSLog(@"%@",error);  //这里打印错误信息

 }];

POST 请求

 AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];

 NSMutableDictionary *parameters = @{@"":@"",@"":@""};

 [manager POST:URL parameters:parameters progress:^(NSProgress * _Nonnull uploadProgress) {

 } success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {

 } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {

 }];

暂时用的比较多的就这两个，用到其他的 再来更新！！

最近又用到了下载，索性 上传下载都研究了一下 ，补充进来

补充试用AFN3.0下载方法

 /**
  *  AFN3.0 下载
  */
 - (void)downLoad{

     //1.创建管理者对象
     AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
     //2.确定请求的URL地址
     NSURL *url = [NSURL URLWithString:@""];

     //3.创建请求对象
     NSURLRequest *request = [NSURLRequest requestWithURL:url];

     //下载任务
     NSURLSessionDownloadTask *task = [manager downloadTaskWithRequest:request progress:^(NSProgress * _Nonnull downloadProgress) {
         //打印下下载进度
         WKNSLog(@"%lf",1.0 * downloadProgress.completedUnitCount / downloadProgress.totalUnitCount);

     } destination:^NSURL * _Nonnull(NSURL * _Nonnull targetPath, NSURLResponse * _Nonnull response) {
         //下载地址
         WKNSLog(@"默认下载地址:%@",targetPath);

         //设置下载路径，通过沙盒获取缓存地址，最后返回NSURL对象
         NSString *filePath = [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES)lastObject];
         return [NSURL URLWithString:filePath];

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

         //下载完成调用的方法
         WKNSLog(@"下载完成：");
         WKNSLog(@"%@--%@",response,filePath);

     }];

     //开始启动任务
     [task resume];

 }

AFN3.0 上传

 /**
  *  AFN 3.0 上传
  *      有两种方式
  *          upLoad1 和 upLoad2
  */

 //第一种方法是通过工程中的文件进行上传
 - (void)upLoad1{

     //1。创建管理者对象
     AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];

     //2.上传文件
     NSDictionary *dict = @{@"username":@""};

     NSString *urlString = @"";
     [manager POST:urlString parameters:dict constructingBodyWithBlock:^(id<AFMultipartFormData>  _Nonnull formData) {
         //上传文件参数
         UIImage *iamge = [UIImage imageNamed:@"123.png"];
         NSData *data = UIImagePNGRepresentation(iamge);
         //这个就是参数
         [formData appendPartWithFileData:data name:@"file" fileName:@"123.png" mimeType:@"image/png"];

     } progress:^(NSProgress * _Nonnull uploadProgress) {

         //打印下上传进度
         WKNSLog(@"%lf",1.0 *uploadProgress.completedUnitCount / uploadProgress.totalUnitCount);
     } success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {

         //请求成功
         WKNSLog(@"请求成功：%@",responseObject);

     } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {

         //请求失败
         WKNSLog(@"请求失败：%@",error);
     }];

 }

 //第二种是通过URL来获取路径，进入沙盒或者系统相册等等
 - (void)upLoda2{
     //1.创建管理者对象
     AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
     //2.上传文件
     NSDictionary *dict = @{@"username":@""};

     NSString *urlString = @"";
     [manager POST:urlString parameters:dict constructingBodyWithBlock:^(id<AFMultipartFormData>  _Nonnull formData) {

         [formData appendPartWithFileURL:[NSURL fileURLWithPath:@"文件地址"] name:@"file" fileName:@"1234.png" mimeType:@"application/octet-stream" error:nil];
     } progress:^(NSProgress * _Nonnull uploadProgress) {

         //打印下上传进度
         WKNSLog(@"%lf",1.0 *uploadProgress.completedUnitCount / uploadProgress.totalUnitCount);
     } success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {

         //请求成功
         WKNSLog(@"请求成功：%@",responseObject);

     } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {

         //请求失败
         WKNSLog(@"请求失败：%@",error);
     }];
 }

监测当前网络状态（网络监听）

 - (void)AFNetworkStatus{

     //1.创建网络监测者
     AFNetworkReachabilityManager *manager = [AFNetworkReachabilityManager sharedManager];

     /*枚举里面四个状态  分别对应 未知 无网络 数据 WiFi
      typedef NS_ENUM(NSInteger, AFNetworkReachabilityStatus) {
          AFNetworkReachabilityStatusUnknown          = -1,      未知
          AFNetworkReachabilityStatusNotReachable     = 0,       无网络
          AFNetworkReachabilityStatusReachableViaWWAN = 1,       蜂窝数据网络
          AFNetworkReachabilityStatusReachableViaWiFi = 2,       WiFi
      };
      */

     [manager setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {
         //这里是监测到网络改变的block  可以写成switch方便
         //在里面可以随便写事件
         switch (status) {
             case AFNetworkReachabilityStatusUnknown:
                 WKNSLog(@"未知网络状态");
                 break;
             case AFNetworkReachabilityStatusNotReachable:
                 WKNSLog(@"无网络");
                 break;

             case AFNetworkReachabilityStatusReachableViaWWAN:
                 WKNSLog(@"蜂窝数据网");
                 break;

             case AFNetworkReachabilityStatusReachableViaWiFi:
                 WKNSLog(@"WiFi网络");

                 break;

             default:
                 break;
         }

     }] ;
 }
