PHP 没有从 XMLhttprequest 接收数据 [英] PHP not receiving data from XMLhttprequest

问题描述

我正在将数据发送到 php 脚本，如下所示:

Hi I am sending data to a php script like so:

function ajax(url,data,success) {
    var request = new XMLHttpRequest();
    request.open("POST", url);
    request.onreadystatechange = function(object) {
        if(request.readyState === 3) {
            success(request);
        }
    };
    request.setRequestHeader("Content-Type","application/json")
    request.send(data);
}

发送的数据是一个字符串化的 javascript 对象.该帖子确实有效，并且该对象显示在 chromes 开发工具的有效负载部分中.但是我发送给请求对象的 php 脚本是空的.php 脚本的内容类型设置为 json.

The data being sent is a stringifyed javascript object. The post definitely works and the object shows in the payload section in chromes dev tools. But the php script I am sending to request object is empty. The php script's content type is set to json.

推荐答案

听起来您遇到了一个众所周知的问题(这里有一些信息:PHP "php://input" vs $_POST)

Sounds like you're experiencing quite a well-known issue (some info here: PHP "php://input" vs $_POST)

您应该能够使用 file_get_contents('php://input') 访问数据

You should be able to access the data with file_get_contents('php://input')
