iOS AFNetworking基本使用

AFNetworking:GitHub

使用AFNetwork来检测网络状态

-(void)reach
{
/*
AFNetworkReachabilityStatusUnknown          = -1,   未知
AFNetworkReachabilityStatusNotReachable     = 0,    未连接
AFNetworkReachabilityStatusReachableViaWWAN = 1,    3G
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);
}];
}

-(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);
}];
}
