php & ajax retriving post data failed

本文关键字：post 数据失败检索 ajax amp php | 更新日期: 2023-09-27

我在尝试通过xmlhttp request:向php发送邮件数据时遇到了一些非常奇怪的问题

这是javascript代码：

function getHeaterDailyConfig(){
    var oReq = new XMLHttpRequest();
    var d = new Date()
    now = [d.getFullYear(), d.getMonth()+1, d.getDate()].join('-');
    var reqArgs = "isDateRequested=1&date=" + now;
    oReq.onload = function() {
        alert(this.responseText);
        daliyConfig = JSON.parse(this.responseText);
    };
    oReq.open("post", "getLatestCfgHeater.php", true);
    oReq.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
    oReq.send(reqArgs);
}

和php:

error_log("start");
error_log(print_r( $_POST['isDateRequested']));
error_log(print_r( $_POST['date']));
error_log("stop");

不幸的是，php给了我非常奇怪的日志，看起来像是从未收到过帖子数据：

怎么了？

我这样试过了。它可以正确发送数据：

<?php
error_reporting(E_ALL);
var_dump($_POST);
?>
<script>getHeaterDailyConfig();
function getHeaterDailyConfig(){
            var oReq = new XMLHttpRequest();
            var d = new Date()
            now = [d.getFullYear(), d.getMonth()+1, d.getDate()].join('-');
            var reqArgs = "isDateRequested=1&date=" + now;
                            oReq.onload = function() {
                            alert(this.responseText);
                            daliyConfig = JSON.parse(this.responseText);
            };
            oReq.open("post", "index.php", true);
            oReq.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
            oReq.send(reqArgs);
    }
    </script>

我得到了这样的数据：

array(2) {
  ["isDateRequested"]=>
  string(1) "1"
  ["date"]=>
  string(8) "2016-1-7"
}
<script>getHeaterDailyConfig();
function getHeaterDailyConfig(){
            var oReq = new XMLHttpRequest();
            var d = new Date()
            now = [d.getFullYear(), d.getMonth()+1, d.getDate()].join('-');
            var reqArgs = "isDateRequested=1&date=" + now;
                            oReq.onload = function() {
                            alert(this.responseText);
                            daliyConfig = JSON.parse(this.responseText);
            };
            oReq.open("post", "index.php", true);
            oReq.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
            oReq.send(reqArgs);
    }
    </script>
