发布请求被切断 [英] Post request gets cut off

问题描述

我在javascript中的发帖请求有问题.

I have a problem with my post request in javascript.

我有以下代码用于发送发帖请求

I have the following code for sending the post request

    var xhttp = new XMLHttpRequest();
        xhttp.onreadystatechange = function() 
        {
            if (this.readyState == 4 && this.status == 200) 
            {   
                //stuff
            }
        };
        xhttp.open("POST", "/deleteUser", true);
        xhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
        xhttp.send("username=" + username);

在我的node.js express应用程序中，我这样收到它

And in my node.js express application i receive it like this

    var username = req.body.username;

现在，这可以正常使用正常字符(数字和字母).但是当我尝试

Now this works perfect with normal characters (numbers and letters). But when i tried

>df)(*&&^%$

作为用户名被切断为

    >df)(* 

我怀疑是因为&.

I suspect it is because of the &.

我的问题:如何防止其被切断.

My question: How do i prevent it from getting cut off.

提前谢谢！

推荐答案

您需要使用 xhttp.send("username =" +encodeURIComponent(用户名));
