从PHP访问POST字符串

Question

I use JQuery.ajax to send a JavaScript object to a PHP script per POST. JQuery sends it in a way that makes it easily accessable from PHP:

JavaScript:

var request = $.ajax({
    url: server,
    dataType: 'text',
    timeout: timeout,
    type: 'POST',
    data: {key:"value"}
});

PHP:

$_POST["key"]

When I send a simple string with $.ajax instead of a JS object, how can I access it in PHP? E.g. when simply sending "data", count($_POST) returns 0.

var request = $.ajax({
    url: server,
    dataType: 'text',
    timeout: timeout,
    type: 'POST',
    contentType: "text/plain",
    data: "data"
});

Do I have to use file_get_contents('php://input') or is there another way?

Yes. If you don't encode the data in a format that PHP can decode automatically, then you have to access the raw data like that.

Remember to set the content-type of the request to text/plain when you do that.
