c# Net Core设置代理(使用自定义Proxy 模式)get post调用接口

Net Core设置代理

有时候我们需要使用代理去调用某些外部接口,浏览器的代理IIS 读取不到,所以只能项目里面指定代理

1. 通过在Startup.cs 文件配置HttpClient

services.AddHttpClient("configured-inner-handler")
.ConfigurePrimaryHttpMessageHandler(() =>
{
return new HttpClientHandler()
{
// AllowAutoRedirect = false,
// UseDefaultCredentials = true,
Proxy = new WebProxy(Configuration["Proxy"]),
UseProxy = true
};
});

2.调用刚刚配置的HttpClient

private readonly HttpClient client;
public BaseCoreService(IConfiguration configuration, IHttpClientFactory IHttpClientFactory,ILogger<BaseCoreService> logger) {
client = IHttpClientFactory.CreateClient("configured-inner-handler");
}
var request = new HttpRequestMessage(HttpMethod.Get, "https://api.weixin.qq.com/sns/jscode2session?grant_type=authorization_code&appid=" + $@"{appid}&secret={secret}&js_code={code.Trim()}");
HttpResponseMessage response = await client.SendAsync(request);
