问题描述
我正在尝试将一些数据发送到 PHP 脚本,然后返回一些其他数据。我不知道如何访问我发送到 PHP 脚本的数据。 stackoverflow 上的这篇文章没有帮助:Reading JSON POST using PHP Is the sent data in $_POST?它是在 $data 还是 $params 中?我如何访问它并打印出来。
这是我所拥有的:
index.html:
.custom-input-container {
display: flex;
flex-direction: column;
min-width: 300px;
background: orange;
}
.custom-input-container .input-group {
display: flex;
flex-direction: row;
}
.custom-input-container .input-group input {
width: 50%;
height: 56px;
}
.custom-input-container input {
height: 56px;
}
xhr.js

data.PHP
const getBtn = document.getElementById('get-btn');
const postBtn = document.getElementById('post-btn');
const sendHttpRequest = (method,url,data) => {
const promise = new Promise((resolve,reject) => {
const xhr = new XMLHttpRequest();
xhr.open(method,url);
xhr.responseType = 'json';
if (data){
xhr.setRequestHeader('Content-Type','application/json');
}
xhr.onload = () => {
resolve(xhr.response);
}
xhr.send(JSON.stringify(data));
});
console.log(promise);
return promise;
};
const getData = () => {
sendHttpRequest('GET','http://localhost/async/data.json').then(responseData => {
console.log(response);
});
};
const sendData = () => {
sendHttpRequest('POST','http://localhost/async/data.PHP',{
email: 'drcrocket@gmail.com',password: 'bowie'
}).then(responseData => {
console.log(responseData);
});
};
getBtn.addEventListener('click',getData);
postBtn.addEventListener('click',sendData);
