值应该从节点js发送到php脚本。当节点js发送值时，php脚本包含逻辑。之后，PHP将计算出的值返回给Node js。问题是当从Node发送值时，Node js中没有输出（返回）。这是正确的php吗？
console.log(response.data.Final); // Undefined
console.log(response.Final); // Undefined
console.log(response.data.result); // Undefined
console.log（响应）

php脚本
<?php
if(isset($_POST['takeFromNode']))
{
$num1 = 10;
$num2 = $_POST['takeFromNode']; // getting from Node Js
$result = ($num1 + $num2); // This result should be return
print(json_encode(['Final' => $result])); // Code to return back
exit();
}
?>
节点脚本
var axios = require('axios')
router.post("/calculate", function (req, res, next)
{
axios.post('http://mytestpage.com/calculate/index.php', {takeFromNode: takeFromNode})
.then(response => {
if(response)
{
console.log(response);
}
})
.catch(error => res.status(500).send(error));
})
答案 0 :(得分：0)
Axios将帖子正文编码为JSON，即默认为Content-Type: application/json。 PHP $_POST[...]希望它是application/x-www-form-urlencoded。
传递对象代码而不是将对象传递给axios.post的第二个参数，
require('querystring').stringify({takeFromNode: takeFromNode})
