AJAX调用Python时打印脚本而非所需信息

Question

我还是个初学者（请多多包涵），但我遇到了一些困惑。为什么我在进行一个简单的ajax请求时，返回的结果却是实际的脚本，而不是我想要的内容呢？

HTML代码如下：

<html>
    <head>
        <meta http-equiv="content-type" content="text/html; charset=utf-8">

        <title>test</title>
        <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
        <script>

            $(function()
            {
                $('#clickme').click(function(){

                    $.ajax({
                        url: "/js/getData.py",
                        type: "POST",
                        datatype:"json",
                        data: {'key':'value','key2':'value2'},
                        success: function(response){
                            console.log('Success!!!!');
                            var data = response;
                            console.log("response.message: " + response.message);
                            console.log("response.keys: " + response.keys);
                            console.log("response.data: " + response.data);
                            console.log("response: " + response);
                            //$('#mommy').html(response);
                        }
                    });
                });
            });

        </script>
</head>
<body>
    <button id="clickme"> click me </button>
    <div id="mommy"></div>
</body>

这是我的Python代码：

#!/usr/bin/env python

import sys
import json
import cgi

fs = cgi.FieldStorage()

sys.stdout.write("Content-Type: application/json")

sys.stdout.write("\n")
sys.stdout.write("\n")


result = {}
result['success'] = True
result['message'] = "The command Completed Successfully"
result['keys'] = ",".join(fs.keys())

d = {}
for k in fs.keys():
    d[k] = fs.getvalue(k)

result['data'] = d

sys.stdout.write(json.dumps(result,indent=1))
sys.stdout.write("\n")

sys.stdout.close()

如果你直接运行getData.py，输出结果是这样的：

Content-Type: application/json

{
 "keys": "", 
 "message": "The command Completed Successfully", 
 "data": {}, 
 "success": true
}

这是控制台的输出：

"Success!!!!" simple.html:19
"response.message: undefined" simple.html:21
"response.keys: undefined" simple.html:22
"response.data: undefined" simple.html:23
"response: #!/usr/bin/env python

import sys
import json
import cgi

fs = cgi.FieldStorage()

sys.stdout.write("Content-Type: application/json")

sys.stdout.write("\n")
sys.stdout.write("\n")


result = {}
result['success'] = True
result['message'] = "The command Completed Successfully"
result['keys'] = ",".join(fs.keys())

d = {}
for k in fs.keys():
    d[k] = fs.getvalue(k)

result['data'] = d

sys.stdout.write(json.dumps(result,indent=1))
sys.stdout.write("\n")

sys.stdout.close() 
" simple.html:24
