c# 【MVC】WebApi通过HttpClient来调用Web Api接口

/// 

/// HttpClient实现Post请求(异步)
/// 
static async void dooPost()
{
	string url = "http://localhost:52824/api/register";
	 //设置HttpClientHandler的AutomaticDecompression
	var handler = new HttpClientHandler() { AutomaticDecompression = DecompressionMethods.GZip };
	//创建HttpClient（注意传入HttpClientHandler）
	using (var http = new HttpClient(handler))
	{
		//使用FormUrlEncodedContent做HttpContent
		var content = new FormUrlEncodedContent(new Dictionary()       
		{    {"Id","6"},
			 {"Name","添加zzl"},
			 {"Info", "添加动作"}//键名必须为空
		 });

		//await异步等待回应

		var response = await http.PostAsync(url, content);
		//确保HTTP成功状态值
		response.EnsureSuccessStatusCode();
		//await异步读取最后的JSON（注意此时gzip已经被自动解压缩了，因为上面的AutomaticDecompression = DecompressionMethods.GZip）
		Console.WriteLine(await response.Content.ReadAsStringAsync());
	}

}
/// 

/// HttpClient实现Get请求(异步)
/// 
static async void dooGet()
{
	string url = "http://localhost:52824/api/register?id=1";
	//创建HttpClient（注意传入HttpClientHandler）
	var handler = new HttpClientHandler() { AutomaticDecompression = DecompressionMethods.GZip };

	using (var http = new HttpClient(handler))
	{
		//await异步等待回应
		var response = await http.GetAsync(url);
		//确保HTTP成功状态值
		response.EnsureSuccessStatusCode();

		//await异步读取最后的JSON（注意此时gzip已经被自动解压缩了，因为上面的AutomaticDecompression = DecompressionMethods.GZip）
		Console.WriteLine(await response.Content.ReadAsStringAsync());
	}
}
///

/// 
static async void dooPut()
{

	string url = "http://localhost:52824/api/register?userid=" + userId;

	//设置HttpClientHandler的AutomaticDecompression
