WeChat third-party web page post request becomes a get request.

Recently I am developing the third webpage of WeChat, and now I encounter a problem. When I use post to jump from page A to page B, page B cannot obtain the data carried by the post.
Looking at the request head, I found that the method has changed to get. What is the situation? How should I modify it?
The code is as follows:

---

<code><script type="text/javascript">

  post("?a=cso",{serviceOrderJson :JSON.stringify(json),id:123});

  function post(URL, PARAMS) {
            var temp = document.createElement("form");
            temp.action = URL;
            temp.method = "post";
            temp.style.display = "none";
            for (var x in PARAMS) {
                var opt = document.createElement("textarea");
                opt.name = x;
                opt.value = PARAMS[x];
                temp.appendChild(opt);
            }
            document.body.appendChild(temp);
            temp.submit();
            return temp;
        }
</script>

Looking at the request head in the browser, I found that the post submission changed to get. What is the situation and how should I modify it?

When you reach page B, it becomes GET, which means that the way you accept parameters on page B is GET

Maybe I was transferred once

When you call post, the method you defined, please pay attention to post("?a=cso",{serviceOrderJson:JSON.stringify(json),id:123});

I seriously suspect that this parameter of yours is wrong. At least now I copy your code and it runs normally

javascript

    var temp = document.createElement("form");
    var PARAMS = [1, 2, 3, 4, 5];

    var URL = '/test/wocaocao2';

    temp.action = URL;
    temp.method = "post";
    temp.style.display = "none";
    for (var x in PARAMS) {
        var opt = document.createElement("textarea");
        opt.name = x;
        opt.value = PARAMS[x];
        temp.appendChild(opt);
    }
    document.body.appendChild(temp);

    temp.submit();

php server

public function wocaocao2Action()
{
    var_dump($_POST);
}
