XMLHTTPrequest发送空帖子 [英] XMLHTTPrequest sending empty post

问题描述

我已经做过很多次了，所以我很困惑为什么它没有通过任何事情.我已经尝试过打印结果(脚本会得到响应并打印文件).

I've done a lot of times before, so I'm honestly confused why this is failing to pass anything. I've tried printing results (script gets a response and prints the file).

function submit_form_inpage(path, data, watchForChange){
    alert(data);
    watchForChange = watchForChange || false;
    var request = new XMLHttpRequest();
    request.open('POST', path, true);
    request.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded; charset=UTF-8');
    if (watchForChange == true) {
        request.onreadystatechange = function () {
            if (request.readyState == 4) {
                document.write(request);
                if (request.status==200 && request.status < 400){
                    var xmldata=request.responseText //retrieve result as an XML object
                    alert("XML:" + xmldata);
                }
                else{
                    alert("An error has occured making the request:" + request.status );
                }
            }
        }
    }
    var temp_string = array_to_string_for_post(data);
    var temp = JSON.stringify(data);
    alert(temp);
    request.send(temp);
}

我的php是

print_r($_POST);

我的结果是

XML: Array ()

尽管事实是传入的数据(在我的警报发送之前已对其进行仔细检查)是

Despite the fact that data passed in (which is double-checked right before being sent by my alert) is

{"reason":"get_stuff","build_name":"test"}

推荐答案

您说过您正在发送表单编码的数据.

You said you were sending form encoded data.

request.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded; charset=UTF-8');

然后您发送了:

temp = JSON.stringify(data);

JSON不是application/json而不是application/x-www-form-urlencoded(PHP本身也不支持).

JSON is application/json not application/x-www-form-urlencoded (and isn't natively supported by PHP anyway).

要么将数据编码为application/x-www-form-urlencoded，要么更正内容类型并在PHP中手动解析.

Either encode your data as application/x-www-form-urlencoded or correct your content-type and parse it manually in PHP.
