香草js中https上的Ajax POST請求

Question

我正在嘗試在普通js中發出Ajax POST請求（該站點沒有jquery）。 我已經嘗試做這樣的事情，但是無法使其正常工作。

var params = { name: "Test"};
var xhr = new XMLHttpRequest();
xhr.open('POST', 'https://www.testurl.com/api/test/save', true);
xhr.setRequestHeader('Content-Type', 'application/json');
xhr.onreadystatechange = function () {
    if (xhr.readyState === 4 && xhr.status === 200) {
        response = JSON.parse(xhr.responseText);
        console.log(reponse);
    }

};
xhr.send(JSON.stringify(params));

我收到此錯誤GET https://www.testurl.com/login.aspx?ReturnUrl=%2fapi%2ftest%2fsave 404（未找到）

有誰知道如何在香草js中使AJAX發布請求與https一起使用？

嘗試以下操作：

$(function () {
      // event handler
      function reqListener () {
        console.log( this.response );
      }

      // get new XHR object
      var newXHR = new XMLHttpRequest();

      // bind our event listener to the "load" event.
      // "load" is fired when the response to our request is completed and without error.
      newXHR.addEventListener( 'load', reqListener );

      // go to http://requestb.in/1k6rql51?inspect to view your request!
      newXHR.open( 'POST', 'http://requestb.in/1k6rql51' );
      //             ^-- IMPORTANT: to send data to the server with it appearing in the url use 'POST'


      // the object below can be crafted in any fashion. In the end you want an Object Literal with your data stored on it.
      var jsonData = { name: 'Ray', password: 'NIGERA RULES?!' };

      // HTTP Protocol can only work with strings when transmitting data over the internet.
      // JSON is a class and .stringify is a class-method. We use it to format
      // the Javascript Data, which lives in memory, to JSON string.
      var formattedJsonData = JSON.stringify( jsonData  );

      // INSPECT WHAT YOU EXPECT, compare the two.
      console.log( jsonData );
      console.log( JSON.parse( formattedJsonData ) );

      // send it off
      newXHR.send( formattedJsonData );
    });
