1、安装引用WebView2

1）使用Nuget界面管理器

相关文档：VS(Visual Studio)中Nuget的使用

2）使用Package Manager命令安装

PM> Install-Package Microsoft.Web.WebView2

3）使用.NET CLI命令安装

2、执行GET请求

var postData = "thing1=hello";
postData += "&thing2=world";
var data = Encoding.ASCII.GetBytes(postData);
MemoryStream stream = new MemoryStream();
stream.Write(data, 0, data.Length);
var request = webView.CoreWebView2.Environment.CreateWebResourceRequest(navigateData.Url,
"GET",stream, "Content-Type: text/html");
webView.CoreWebView2.NavigateWithWebResourceRequest(request);
stream.Close();
stream.Dispose();

3、执行POST请求

var postData = "thing1=hello";
    postData += "&thing2=world";
var data = Encoding.ASCII.GetBytes(postData);
MemoryStream stream = new MemoryStream();
stream.Write(data, 0, data.Length);
var request = webView.CoreWebView2.Environment.CreateWebResourceRequest(navigateData.Url, 
              "POST", stream, "Content-Type: application/x-www-form-urlencoded");
webView.CoreWebView2.NavigateWithWebResourceRequest(request);
stream.Close();
stream.Dispose();
