验证流程

服务器端接入

Startup 配置：

services.AddHttpClient<TencentCaptchaHelper>(client => client.Timeout = TimeSpan.FromSeconds(3))   .ConfigurePrimaryHttpMessageHandler(() => new NoProxyHttpClientHandler()); services.AddTencentCaptchaHelper(options => {   options.AppId = Configuration["Tencent:Captcha:AppId"];   options.AppSecret = Configuration["Tencent:Captcha:AppSecret"]; });

前端接入

前端接入这里不作多介绍了，接入方式多种多样，具体可以参考官方文档：https://cloud.tencent.com/document/product/1110/36841

下面的代码是 angular spa 在前端接入的核心代码

 private loadCaptcha(): void {   var tCaptcha = document.getElementById("tCaptcha");   if (tCaptcha) {    this.InitCaptcha();    return;   }   let script = <any>document.createElement('script');   script.id = "tCaptcha";   script.type = 'text/javascript';   script.src = "https://ssl.captcha.qq.com/TCaptcha.js"   if (script.readyState) { //IE    script.onreadystatechange = () => {     if (script.readyState === "loaded" || script.readyState === "complete") {      this.InitCaptcha();     }    };   } else { //Others    script.onload = () => {     this.InitCaptcha();    };   }   document.getElementsByTagName('body')[0].appendChild(script);  }  private InitCaptcha(): void {   let captchaDom = document.getElementById('TencentCaptcha1');   if (!captchaDom) {    return;   }   this.tencentRecaptcha = new TencentCaptcha(    captchaDom, appId, (res) => {     this.captchaValid = false;     console.log(res);     // res（用户主动关闭验证码）= {ret: 2, ticket: null}     // res（验证成功） = {ret: 0, ticket: "String", randstr: "String"}     if (res.ret === 0) {      this.captchaInfo.nonce = res.randstr;      this.captchaInfo.ticket = res.ticket;      this.captchaValid = true;      this.tencentRecaptcha.destroy();      let button = <HTMLElement>document.getElementById("btnSubmit");      button.click();     }    }   );   console.log(`captcha inited`);   this.tencentRecaptcha.show();  }
