一、AFNetWorking简介
AFNetWorking是一个轻量级的网络请求API类库，是以NSURLSession，NSOperation和其他方法为基础的核心代码，可以进行网络请求等操作
在这里我们需要先导入第三方库：

get请求
//get请求的方法
-(void)getMethod{
//初始化网络会话管理对象
AFHTTPSessionManager* httpManager=[AFHTTPSessionManager manager];
//设置请求的响应序列化
// httpManager.responseSerializer=[AFHTTPResponseSerializer serializer];
//我们已知返回的数据类型为JSON
httpManager.responseSerializer=[AFJSONResponseSerializer serializer];
//根据报错设置响应数据的可接受类型
httpManager.responseSerializer.acceptableContentTypes=[NSSet setWithObjects:@"text/plain",@"text/html",@"text/xml",@"application/xml",@"application/json",nil];
//进行发起get请求
//第一个参数：网址
//第二个参数：一般是字典类型，网络请求的参数
//第三个参数：如果是下载任务，该block中可以监测下载进度
//第四个参数：网络请求成功会执行的block
//第五个参数：网络请求失败会执行的block
//参数字典
NSDictionary* dic=@{@"date":@"20151101",@"startRecord":@"1",@"len":@"5",@"udid":@"1234567890",@"terminalType":@"Iphone",@"cid":@"213"};
[httpManager GET:@"http://ipad-bjwb.bjd.com.cn/DigitalPublication/publish/Handler/APINewsList.ashx" parameters:dic progress:^(NSProgress * _Nonnull downloadProgress) {
//已经下载的资源大小
NSInteger complete=downloadProgress.completedUnitCount;
//资源的总大小
NSInteger total=downloadProgress.totalUnitCount;
float completeProgress=0;
if (total) {
//下载的进度
completeProgress = complete*1.0/total;
}
NSLog(@"已经下载的---%ld",(long)complete);
NSLog(@"总大小---%ld",(long)total);
NSLog(@"进度为---%ld",(long)completeProgress);
} success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
NSLog(@"网络请求成功");
// NSDictionary* dic=[NSJSONSerialization JSONObjectWithData:responseObject options:(NSJSONReadingAllowFragments) error:nil];
NSLog(@"---%@",responseObject);
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
NSLog(@"---%@",error.debugDescription);
}];
}
post请求
//post请求的方法
-(void)postMethod{
//初始化网络会话管理对象
AFHTTPSessionManager* httpManager=[AFHTTPSessionManager manager];
//设置请求的响应序列化
// httpManager.responseSerializer=[AFHTTPResponseSerializer
// serializer];
//我们已知返回的数据类型为JSON
httpManager.responseSerializer=[AFJSONResponseSerializer serializer];
//根据报错设置响应数据的可接受类型
httpManager.responseSerializer.acceptableContentTypes=[NSSet setWithObject:@"text/plain"];
NSDictionary* dic=@{@"date":@"20151101",@"startRecord":@"1",@"len":@"5",@"udid":@"1234567890",@"terminalType":@"Iphone",@"cid":@"213"};
[httpManager POST:@"http://ipad-bjwb.bjd.com.cn/DigitalPublication/publish/Handler/APINewsList.ashx" parameters:dic constructingBodyWithBlock:^(id<AFMultipartFormData> _Nonnull formData) {
} progress:^(NSProgress * _Nonnull uploadProgress) {
} success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
NSLog(@"网络请求成功");
// NSDictionary* dic=[NSJSONSerialization JSONObjectWithData:responseObject options:(NSJSONReadingAllowFragments) error:nil];
NSLog(@"---%@",responseObject);
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
NSLog(@"---%@",error.debugDescription);
}];
}
下载
//downLoad
-(void)downLoadMethod{
//初始化网络会话管理对象
AFHTTPSessionManager* httpManager=[AFHTTPSessionManager manager];
//设置请求的响应序列化
httpManager.responseSerializer=[AFHTTPResponseSerializer serializer];
NSURL* url=[NSURL URLWithString:@"http://www.xiaobuqi.com//d/file/joke/2016-01/1452962161.mp4"];
NSURLRequest* rq=[NSURLRequest requestWithURL:url];
NSURLSessionDownloadTask* task= [httpManager downloadTaskWithRequest:rq progress:^(NSProgress * _Nonnull downloadProgress) {
//已经下载的资源大小
NSInteger complete=downloadProgress.completedUnitCount;
//资源的总大小
NSInteger total=downloadProgress.totalUnitCount;
float completeProgress=0;
if (total) {
//下载的进度
completeProgress = complete*1.0/total;
}
NSLog(@"已经下载的---%ld",(long)complete);
NSLog(@"总大小---%ld",(long)total);
NSLog(@"进度为---%f",completeProgress);
} destination:^NSURL * _Nonnull(NSURL * _Nonnull targetPath, NSURLResponse * _Nonnull response) {
//需要将下载好的资源存储的路径，需要在该block中返回
NSString* destinationPath=@"/Users/xalo/Desktop/aaa.mp4";
return [NSURL fileURLWithPath:destinationPath];
} completionHandler:^(NSURLResponse * _Nonnull response, NSURL * _Nullable filePath, NSError * _Nullable error) {
NSLog(@"下载完成");
}];
[task resume];
}
监测网络环境
//监测网络环境
-(void)checkNet{
AFNetworkReachabilityManager* reachabilityManager=[AFNetworkReachabilityManager sharedManager];
//当网络环境发生变化时就会执行该block
[reachabilityManager setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {
switch (status) {
case AFNetworkReachabilityStatusNotReachable:
NSLog(@"无法连接网络");
break;
case AFNetworkReachabilityStatusReachableViaWWAN:
NSLog(@"连接到蜂窝煤网络");
break;
case AFNetworkReachabilityStatusReachableViaWiFi:
NSLog(@"连接Wifi");
break;
case AFNetworkReachabilityStatusUnknown:
NSLog(@"未知错误");
break;
default:
break;
}
}];
//开始检测
[reachabilityManager startMonitoring];
//停止监测网络
// [reachabilityManager stopMonitoring];
}
