Question

请帮我解决这个问题。

我想从$ _POST数组中获取数据，但它返回为空，但php：// input返回所有数据。

这是我的代码：

echo $_SERVER['CONTENT_TYPE'];

$post = file_get_contents('php://input');
print "post data: <pre>";
var_dump($post);
echo "-----------------------<br>";
var_dump($_POST);

输出：

application/x-www-form-urlencodedDATA:

string(6529)

Answer 1

您是否尝试打印$ _POST进行图片文件上传，那么您错了就应该使用$ _FILES

var_dump($_FILES);

Answer 2

更新：我已经使用您的帖子正文进行了一些测试。无法重现您的问题。

解决方法：使用函数parse_str($post);：

parse_str($post, $array);
var_dump($array);

输出：

array(3) {
  'jform' =>
  array(61) {
    'sitename' =>
    string(4) "Test"
    'offline' =>
    string(1) "0"
    'display_offline_message' =>
    string(1) "1"
    'offline_message' =>
    string(70) "This site is down for maintenance.<br /> Please check back again soon."
    'offline_image' =>
    string(0) ""
    'editor' =>
    string(7) "tinymce"
    'captcha' =>
    string(1) "0"
    'access' =>
    string(1) "1"
    'list_limit' =>
    string(2) "20"
    'feed_limit' =>
 ... // many will follow

Answer 3

您的帖子数据似乎无法正确编码。帖子数据应采用

的形式

key1=value1&key2=value2&key3=value3.....

您需要urlencode()除&和=

以外的所有内容

我也认为你试图通过post vars发送一个关联数组。（例如jform [...]）虽然$ _POST本身就是一个关联数组，但我认为不可能通过它发送关联数组（没有任何处理）

虽然php：//输入和原始发布数据可用，但$ _POST数组为空
