從客戶端JavaScript實現AJAX/HTTP請求：http.js

http.js能夠從客戶端JavaScript實現AJAX/HTTP請求。

http.js 提供了一種超級簡單，超級簡易的方式來實現AJAX/HTTP請求 。它基本上是一個很小的幾個功能，以簡化XMLHttpRequest的調用。

Usage

http.js currently all HTTP methods. GET and POST requests are supported in short-hand form.

Pass in your options to the request function (all are optionall; defaults are shown):

var options = {
    method: "GET",               // The method to use
    url: "./",                   // The URL to request
    async: true,                 // Whether to make the request asynchronously
    data: null,                  // Any data you'd like to send
    contentType: "text/plain",   // The MIME type of the content you're sending
    onload: function() { }       // Your onload callback function
}

Or use the shorthand functions get and post, which can take in a similar options object but without the need for a method.

Example usage

We can try a simple GET request:

http.get({
    url: "http://reqr.es/api/users",
    onload: function() { console.log(JSON.parse(this.responseText)) }
});

Or a POST request:

var data = { name: "http.js" }
http.post({
    url: "http://reqr.es/api/awesome-stuffs",
    data: JSON.stringify(data),
    contentType: "application/json",
    onload: function() { console.log(JSON.parse(this.responseText)) }
});

Even a random DELETE:

http.request({
    method: "DELETE",
    url: "http://reqr.es/api/users/2",
    onload: function() { console.log(JSON.parse(this.status)) }
});
