1、网络监测

/**

 *  网络检测

 */

- (void)networkingMonitoring

{

    //打开网络监测

    [[AFNetworkReachabilityManager sharedManager] startMonitoring];

    [[AFNetworkReachabilityManager sharedManager] setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {

        if (status == AFNetworkReachabilityStatusUnknown)

        {

            NSLog(@"网络未知");

        }

        if (status == AFNetworkReachabilityStatusNotReachable)

        {

            NSLog(@"无网络访问");

        }

        if (status == AFNetworkReachabilityStatusReachableViaWWAN)

        {

            NSLog(@"手机网络");

        }

        if (status == AFNetworkReachabilityStatusReachableViaWiFi)

        {

            NSLog(@"WiFi网络");

        }

    }];

}

2、网络请求

get请求

- (void)requestTool:(NSString *)url

{

    AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];

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

        NSLog(@"下载的速度");

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

        NSLog(@"请求成功");

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

        NSLog(@"错误信息:%@",error);

    }];

}

post请求

    AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];

    NSMutableDictionary *dic = [NSMutableDictionary dictionary];

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

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

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

    }];

3、下载

/**

 *  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];

}

4、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);

    }];

}
