PHP JSON响应包含HTML标头 [英] PHP JSON response contains HTML headers
问题描述
我遇到一个奇怪的问题，我试图编写一个PHP页面，该页面将一些JSON返回给Jquery AJAX调用.问题在于，尽管将内容类型设置为application/json，但响应似乎总是包含HTML标头.
I've got a strange problem where I'm trying to write a PHP page that returns some JSON to a Jquery AJAX call. Problems is that despite setting the content type to application/json, the response always seems to include the HTML header.
这是PHP代码:
// some code that generates an array
header("Content-type: application/json");
echo json_encode($return);
然后用Java语言编写:
Then in Javascript:
$.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!');
}
});
响应似乎总是这样的:
<!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
根据响应标头，它肯定认为它是JSON:
And according to the response header it certainly thinks it's 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，它就会警告错误！".每次都会被解雇，这是可以理解的... 任何人都知道为什么将HTML包含在响应中?
Whenever I run the code and it alert "Error!" gets fired every time, which is understandable... Anyone got any ideas why the HTML is being included in the response?
推荐答案
好，我找到了自己的答案，好像我在php.ini文件中打开了tidyhtml，并且有一个
Ok, I found my own answer, looks like I had tidyhtml turned on inside my PHP.ini file, and had a
ob_start("ob_tidyhandler");
在我的一个全局软件包中.评论出来，一切正常.谢谢大家的宝贵时间！
