.NetCore HttpClient Proxy 设置全局代理

.NetCore HttpClient Proxy 设置全局代理

1. 环境 .net6.0,使用的是 HttpClient

   • 在Program.cs里面

     service.AddHttpClient<HttpClientHelper>();
     
     

2. 重点是在 HttpClientHelpe 的构造函数里面设置

   • 构造函数会接受来自Program.cs里面注入的 HttpClient 因此我可以直接对其进行配置

   • 方式一配置,全局的HttpClient的代理

     • 

   • 方式二配置,当前构造函数里面的HttpClient的代理

     • 

   • 完整代码如下,如有需要自行修改

     • private readonly HttpClient _httpClient;
       
               public HttpClientHelper(HttpClient httpClient1)
               {
                   #region Proxy 
       
                   //1.设置带用户和密码的代理
                   var Address = ConfigCommon.Configuration["Proxy:Address"];//地址
                   var Account = ConfigCommon.Configuration["Proxy:Account"];//用户名
                   var Password = ConfigCommon.Configuration["Proxy:Password"];//密码
                   var webProxy = new WebProxy(Address, false);
                   webProxy.BypassProxyOnLocal = true;
       
                   //2.如果有用户名和密码需要以下设置
                   ICredentials jxCredt = new NetworkCredential(Account, Password);
                   webProxy.Credentials = jxCredt;
       
                   #region 方式一
       
                   HttpClient.DefaultProxy = webProxy;
       
                   #endregion
       
                   #region 方式二 注释 
                   var proxyHttpClientHandler = new HttpClientHandler
                   {
                       Proxy = webProxy,
                       UseProxy = true
                   };
                   HttpClient httpClient = new HttpClient(proxyHttpClientHandler);
       
       
                   _httpClient = httpClient;
                   #endregion
       
                   //超时时间设置
                   httpClient.Timeout = TimeSpan.FromMinutes(5);
       
                   //设置Header
                   httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
                   httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/x-www-form-urlencoded"));
       
                   #endregion
                   _httpClient = httpClient;
               }
       
       

3. appsettings.json里面的Proxy配置如下

   • "Proxy": {
         "Address": "127.0.0.1:6666",
         "Account": "username",
         "Password": "pwd"
       }
