jQuery.ajax() log the HTTP request

Question

I have a function that sends an HTTP POST request and i want to log it for debugging purposes. Here is the function:

function serverRequest(URL, DATA, callback) {
    $.ajax({
        url: URL,
        type: "POST",
        dataType: "text",
        contentType: "text/xml",
        processData: false,
        data: DATA,
        success: function (response) {
            console.log(response);
            callback(response);
        },
        error: function (response) {
            console.log(response);
            callback(null);
        }
    });
}

How can i log the whole HTTP POST request (HTTP Header + data), as soon as it is send?

Thanks.

If you are using chrome or firefox you can see the request in developper tools. For chrome, just hit Ctrl+Shift+J and open the network tab. — Thomas

I don't see my request. I just see in the console tab what i am logging. Isn't there any way to log the request just like i log the response? — Christos Baziotis

Look for the tab "Network" (not the Console tab) on your Developer Tools (Ctrl+Shift+J) if you are using Chorme, or anythig similar if you are using another browser.

Even after that, if you want to log the XHtmlRequest, you can always do (if your browser supports console.log):

var xhr = $.ajax(...);
console.log(xhr);

Hope I've helped.

fwiw console.log(xhr); prints `[object Object]

Wrap the xhr as such JSON.stringfy(xhr) to see the plain text representation of the JSON object.
