javascript - Jquery AJAX json - 未调用

Question

我无法连接到Web服务，尝试了很多不同的选项并更改参数，提示在哪里挖掘？这是我第一次通过 AJAX 连接的经历，我通过其他客户端工作进行了尝试。

var xhr = $.ajax({
     url: webserUrl,
     type: "GET",
     data: JSON.stringify({ "Tabn": "1","Vaccurrent": "1","Vacnext": "1" }),
     cache: false,
     crossDomain: true,
     username: "user", 
     password: "password",
     processData: false,
     contentType: "application/json",
     dataType: "json",
     headers: {
        "Accept": "application/json; odata=verbose"
    },
     xhrFields: {
     withCredentials: true
                },
     crossDomain: true,
      success: OnSuccess, 
      error: OnError
        });<br/>
        function OnSuccess(data, status)
    {
        alert(data);
    }
    function OnError(xhr, ajaxOptions, thrownError, request, error)
    {
        alert('xrs.status = ' + xhr.status + '\n' + 
            'thrown error = ' + thrownError + '\n' +
            'xhr.statusText = '  + xhr.statusText + '\n' +
            'request = ' + request + '\n' +
            'error = ' + error);
            console.log('xrs.status = ' + xhr.status + '\n' + 
            'thrown error = ' + thrownError + '\n' +
            'xhr.statusText = '  + xhr.statusText + '\n' +
            'request = ' + request + '\n' +
            'error = ' + error);
    }<br/>
 });

错误:
xrs.status = 200
抛出错误=未定义
xhr.statusText = 确定
请求=未定义
错误=未定义

谢谢大家的回答，更改为带有 wsdl 端点的 url，还将内容类型更改为:“text/xml; charset =\” utf-8\“” 并且有效。
