和字符中断通过PHP接收JSON

Question

I have an array with more objects. If one object contains & character, every object after the & is not received by php. What might be the problem?

THIS IS THE AJAX

xmlhttp.open("POST", "get.php");
xmlhttp.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
xmlhttp.send('data='+JSON.stringify(x));

THIS IS THE PHP

$json = $_POST['data'];
echo $json;

When entered

a&b

I got

[[{"x":x,"y":"x","z":"z"}],[{"w":a

Answer 1

您还必须使用encodeURIComponent函数：

xmlhttp.send('data=' + encodeURIComponent(JSON.stringify(x)));

Answer 2

The problem is that stringify does not escape special characters like the & sign. You should use encodeURIComponent(JSON.stringify(x))
