AFNetworking是一个轻量级的iOS网络通信类库。它建立在NSURLConnection和NSOperation等类库的基础上，让很多网络通信功能的实现变得十分简单。
- 使用AFNetwork来检测网络状态
-(void)reach
{
/*
AFNetworkReachabilityStatusUnknown = -1, 未知
AFNetworkReachabilityStatusNotReachable = 0, 未连接
AFNetworkReachabilityStatusReachableViaWWAN = 1, 3G 花钱
AFNetworkReachabilityStatusReachableViaWiFi = 2, WIFI
*/
//如果要检测网络状态的变化，必须用检测管理器的单例
[[AFNetworkReachabilityManager sharedManager] startMonitoring];
[[AFNetworkReachabilityManager sharedManager] setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {
NSLog(@"status = %ld",status);
}];
}
- 使用AFNetwork 的 GET方法 获取信息
-(void)getRequestWithUrl:(NSString *)urlString WithParameters:(NSDictionary *)dictionary
{
NSURL *url = [NSURL URLWithString:urlString];
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
[manager GET:url.absoluteString parameters:dictionary progress:^(NSProgress * _Nonnull downloadProgress) {
NSLog(@"下载 = %@",downloadProgress);
} success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
//通知
[[NSNotificationCenter defaultCenter] postNotificationName:@"center" object:nil userInfo:responseObject];
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
NSLog(@"错误 = %@",error);
}];
}
- 使用AFNetwork 的 POST 上传纯文本信息
-(void)postWeiboWithUrl:(NSString *)urlString WithParameters:(NSDictionary *)dictionary
{
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
//返回格式
//这里得到的是 JSon 数据，默认的 responseSeroalizer 也是 JSon 数据
manager.responseSerializer = [AFJSONResponseSerializer serializer];
//得到的是 NSData 数据
// manager.responseSerializer = [AFHTTPResponseSerializer serializer];
//接受一些类型
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json", nil];
NSURL *url = [NSURL URLWithString:urlString];
[manager POST:url.absoluteString parameters:dictionary progress:^(NSProgress * _Nonnull uploadProgress) {
NSLog(@"上传 = %@",uploadProgress);
} success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
NSLog(@"响应 = %@",responseObject);
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
NSLog(@"错误 = %@",error);
}];
}
- 使用AFNetwork 的 POST 方法 上传文本和图片
-(void)postWeiboWithUrl:(NSString *)urlString WithParameters:(NSDictionary *)dictionary WithImageName:(NSString *)imageName
{
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
manager.responseSerializer = [AFJSONResponseSerializer serializer];
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json", nil];
NSURL *url = [NSURL URLWithString:urlString];
[manager POST:url.absoluteString parameters:dictionary constructingBodyWithBlock:^(id<AFMultipartFormData> _Nonnull formData) {
NSData *data = UIImagePNGRepresentation([UIImage imageNamed:@"voiceChange"]);
// NSData *data1 = UIImageJPEGRepresentation([UIImage imageNamed:@"voiceChange"], 0.5);
[formData appendPartWithFileData:data name:@"pic" fileName:@"测试.png" mimeType:@"png"];
} progress:^(NSProgress * _Nonnull uploadProgress) {
NSLog(@"上传 = %@",uploadProgress);
} success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
NSLog(@"响应 = %@",responseObject);
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
NSLog(@"错误 = %@",error);
}];
}
