[Shell脚本]在Shell脚本中获取httpreqest POST

Question

Is it possible to get POST data from client side( by ajax) and process it in shell script?

I use jQuery to send data to my server side as

$.ajax({
    url: "test.cgi",
    type: "post",
    data:{
        test: "123"
    },
    dataType: "json"
});

and I hope I can process the data( as '123' in the sample) in my shell script.

If I use GET , I can use $QUERY_STRING to get data in my server side,

but I afraid the datas I send to server are too much, so I use POST instead.

My server is Linux and my shell script is Bourne Shell( starts with #!/bin/sh ).

Or is there others method to handle this situation?

Thanks in advanced!.

Edit:

I have web page called test.html, and there is input box, user write '123' in the input box, then click button( not type='submit', just type='button', because I want to use ajax, not use form and let web page load to server side web page), the button will run the ajax in POST to server side cgi--- test.cgi

In test.cgi, I want to get the data that client side POST to it and process it( as save the data '123' to a file.

What you use to send the POST is completely irrelevant. If your shell script is invoked as a regular CGI script, the POST data will be available on standard input.

#!/bin/sh
cat >file

Perhaps you want to add unwrapping of the application/x-www-form-urlencoded container but in essence, the above is all it takes to do what you are asking.

Here's the obligatory caution -- you probably don't actually want to use shell script for this. Please investigate more secure, more robust, more specialized alternatives.
