Question

我有这个执行ajax POST的功能：

function consultaruserID(){
    if (window.XMLHttpRequest){ // code for IE7+, Firefox, Chrome, Opera, Safari
        xmlhttp=new XMLHttpRequest();
        } else { // code for IE6, IE5
        xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
    }

var userID = document.getElementById('userID').value;
var captcha = document.getElementById('captcha').value;
var token = encodeURIComponent(cToken);
    var params = "userID="+userID + "&captcha="+captcha + "&token="+token;


    xmlhttp.open('POST','/sys/getdata.php',false);
    xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
    xmlhttp.setRequestHeader("Content-length", params.length);
    xmlhttp.setRequestHeader("Connection", "close");
    xmlhttp.send(params);


    alert (xmlhttp.responseText);

}

请注意，字符串标记的长度约为2000，并且涉及一些特殊字符。因此我使用 encodeURIComponent（cToken）;

getdata.php处理所有数据并返回一个字符串。 100％工作。

现在，使用下面的代码在发布后返回SUCCESS，但它不会给我带来getdata.php预期的字符串。

$.post("/sys/getdata.php",
    {userID: $('#userID').val(),
     captcha: $('#captcha').val(),
     token: encodeURIComponent(cToken)
    },
    function(data,status){
    alert("Data: " + data + "\nStatus: " + status);
    }
);

在getdata.php上我调试了来自两种方法的ajax的$ _POST。两种方法似乎都正确发布。但是，处理令牌的功能（不是我的）会以某种方式拒绝来自ajax。

我在这里错过了什么吗？

cToken的样本：

Answer 1

您不应该对cToken进行URI编码。当jQuery将对象文字转换为查询字符串时，它将自动应用URI编码。

Answer 2

您的令牌似乎包含未正确传递的额外参数，请尝试传递数据字符串：

var userID = document.getElementById('userID').value;
var captcha = document.getElementById('captcha').value;
var token = encodeURIComponent(cToken);
var params = "userID="+userID + "&captcha="+captcha + "&token="+token;

$.post("/sys/getdata.php",
    params,
    function(data,status){
    alert("Data: " + data + "\nStatus: " + status);
    }
);

$ .post未正确发布
