带有Cors-Anywhere的jQuery Recaptcha v2缺少输入响应

问题描述 投票：0回答：1

我在输入Recaptcha时遇到麻烦。

这是我的jQuery Call中的代码。

function getCaptchaData(website, cellNumber, firstName, lastName, emailAddress, password) {
  //return new Promise(function(resolve, reject) {
    $.ajax({
      url: website,
      type: 'POST',
      cache: false,
      contentType: 'application/x-www-form-urlencoded',
      success: function(data) {
        // alert(website);
        // alert(data);
        alert("getCaptchaData Success!!");
        json_string = JSON.stringify(data);
        alert(json_string);
        //resolve(json_string); // Resolve promise and go to then()
        callLoadPromoter(cellNumber, firstName, lastName, emailAddress, password);
        return true;
      },
      error: function(err) {
        alert("getCaptchaData Fail");
        //alert(website);
        //alert(err);
        //err_json = JSON.stringify(err);
        //console.log(err_json);
        //alert(err_json);
        return false;
        //reject(err); // Reject the promise and go to catch()
      }
    });
  //});
}

这是我的Recaptcha v2网址：

我以为可能是cors-everywhere.herokuapp部分，所以我使用cURL进行了检查。看来并非如此。这是我使用的cURL代码：

这是我得到的答复：

所以我以详细模式运行了cURL，它提供了一些有趣的东西。

出于某种原因，它会在与号之间截断URL。关于为什么这样做以及如何停止它的任何建议都将有所帮助。

我引用了cURL字符串，它在cURL级别起作用。

...

{
  "success": true,
  "challenge_ts": "2019-12-21T12:49:35Z",
  "hostname": "127.0.0.1"
}

但是现在我如何在关于jQuery的实际应用程序中复制这种成功？

真正的问题是$.ajax(...)没有给予足够的控制权来使用cors-anywhere.herokuapp.com网站。您必须控制标题，因此您应该使用XmlHttpRequest()对象。

function getCaptchaData(website, cellNumber, firstName, lastName, emailAddress, password)
{

  var xhr = new XMLHttpRequest();
  var url = website;
  //console.log(data);
  //alert(data);        
  xhr.open("POST", url, true);
  xhr.setRequestHeader("Content-Type","application/x-www-form-urlencoded");
  xhr.setRequestHeader("Accept","application/json");
  xhr.setRequestHeader("X-Requested-With","XMLHttpRequest");
  xhr.onreadystatechange = function () {
      if (this.readyState == 4 && this.status == 200) {

        alert("getCaptchaData Success!!");
        //resolve(json_string); // Resolve promise and go to then()
        callLoadPromoter(cellNumber, firstName, lastName, emailAddress, password);
        return true;

      }
      else if (this.readyState == 4 && this.status == 404)
      {
        alert("getCaptchaData Fail!  File not found.");
      }
      else
      {
        alert("getCaptchaData: Ready State: " + this.readyState + " Status: " + this.status);
      }
    }

  xhr.send();

}

这有效。希望对您有帮助。
