這期內(nèi)容當(dāng)中小編將會(huì)給大家?guī)碛嘘P(guān)怎么在asp.net core中接入騰訊驗(yàn)證碼,文章內(nèi)容豐富且以專業(yè)的角度為大家分析和敘述,閱讀完這篇文章希望大家可以有所收獲。

private const string TencentCaptchaVerifyUrl = "https://ssl.captcha.qq.com/ticket/verify";
private readonly TencentCaptchaOptions _captchaOptions;
private readonly ILogger _logger;
private readonly HttpClient _httpClient;
public TencentCaptchaHelper(
IOptions<TencentCaptchaOptions> option,
ILogger<TencentCaptchaHelper> logger,
HttpClient httpClient)
{
_captchaOptions = option.Value;
_logger = logger;
_httpClient = httpClient;
}
public async Task<bool> IsValidRequestAsync(TencentCaptchaRequest request)
{
// 參考文檔:/tupian/20230522/
var response = await _httpClient.GetAsync(

var result = responseText.JsonToType<TencentCaptchaResponse>();
if (result.Code == 1)

}
}
return false;
}
}
}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
前端接入這里不作多介紹了,接入方式多種多樣,具體可以參考官方文檔:https://cloud.tencent.com/document/product/1110/36841
下面的代碼是 angular spa 在前端接入的核心代碼
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(用戶主動(dòng)關(guān)閉驗(yàn)證碼)= {ret: 2, ticket: null}
// res(驗(yàn)證成功) = {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();
