我有一个奇怪的问题,我正在尝试编写一个PHP页面,将一些JSON返回给Jquery AJAX调用.问题是尽管将内容类型设置为application/json,但响应似乎总是包含HTML标头.
这是PHP代码:
// some code that generates an array
header("Content-type: application/json");
echo json_encode($return);
然后在Javascript中:
$.ajax({
url: '/VAPHP/services/datatable.php',
dataType: 'json',
data:
{
type: 'invoices'
},
success: function(data)
{
// show a message saying it's been sent!
alert('Success!');
},
error: function(XMLHttpRequest, textStatus, errorThrown) {
alert('Error!');
}
});
响应似乎总是这样:
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 3.2//EN">
<html>
<head>
<title></title>
</head>
<body>
{"aaData":[["2007-08-01","91109507","Invoice","10.000000","AUD"],["2007-08-02","91110103","Invoice","5.000000","AUD"],["2007-08-02","91110122","Invoice","305.000000","AUD"],["2007-08-02","91110129","Invoice","320.000000","AUD"],["2007-08-03","91111146","Credit
for Returns","10.000000","AUD"],["2007-08-06","91111895","Credit
for Returns","320.000000","AUD"],["2007-09-03","91128486","Credit
Memo","5.000000","AUD"],["2007-09-03","91128487","Credit
etc, etc
根据响应标题,它肯定认为它是JSON:
HTTP/1.1 200 OK
Content-Type: application/json
Server: Microsoft-IIS/7.5
X-Powered-By: PHP/5.3.3
每当我运行代码时它会提示"错误!" 每次都被解雇,这是可以理解的......任何人都有任何想法为什么HTML被包含在响应中？
