Light-http is a very light library it could easily make a http & https request, also support asynchronous and synchonrous at the same time.
You can use this library on server side Node.js and client side JavaScript.

Let's try it !
How to install light http on server side
npm install -g light-http
Example
Asynchronous
var http = require('light-http');
var header = {"user-agent": "Mozilla/5.0 xx"};
var url = "https://www.google.com.tw";
// Method GET
http.get(url, {"key":"value"}, header, function(response) {
var html = response;
var respHeaders = http.getResponseHeaders();
console.log(respHeaders['set-cookie']);
});
// Method POST
http.post(url, {"key":"value"}, header, function(content, err, respObj) {
if (!err) {
console.log("Response content = ", content);
console.log("Response header = ", respObj.headers);
console.log("Response binary data = ", respObj.binary);
}
});
Synchronous - Using Promise
var http = require('light-http');
var header = {"user-agent": "Mozilla/5.0 xx"};
var url = "https://www.google.com.tw";
// Method GET
http.get(url, {"key":"value"}, header)
.then(function(response) {
...
}, function (err) {...});
// Method POST
http.post(url, {"key":"value"}, header)
.then(function(response) {
...
}, function (err) {...});
Upload file
var http = require('light-http');
var header = {"user-agent": "Mozilla/5.0 xx"};
var url = "https://www.google.com.tw";
http.addFile("fileData", "/var/www/file.txt");
http.addFile("fileData2", "/var/www/file2.txt");
http.addFileContent("fileData3", "file3.txt", "The file content");
http.post(baseUrl + "/xxx.php", {"age":"13"}, header, function(response) {
var resp = JSON.parse(response);
});
Make a Raw HTTP request
var http = require('light-http');
var host = "www.google.com.tw";
var port = 80;
var path = "/";
var cookie = 'SID=; HSID=; SSID=jjj; APISID=;';
var msg = [
"GET " + path + " HTTP/1.1",
"host: " + host,
"cookie: " + cookie,
"\r\n"].join("\r\n");
http.rawRequest(host, port, msg)
.then(function (resp) {
console.log(resp);
});
//http.rawRequest(host, port, msg, function (resp) {
// console.log(resp);
//});
Make a Raw HTTPS request (ssl)
You have two ways to indicate this library to use https protocol
- Set the port to be "443:ssl".
- Add https:// before the value of host.
Example
var http = require('light-http');
var host = "www.google.com.tw";
var url = "https://" + host;
var port = 443; // or port = "443:ssl"
var path = "/";
var cookie = 'SID=; HSID=; SSID=jjj; APISID=;';
var msg = [
"GET " + path + " HTTP/1.1",
"host: " + host,
"cookie: " + cookie,
"\r\n"].join("\r\n");
http.rawRequest(url, port, msg)
.then(function (resp) {
console.log(resp);
});
Using lightHttp library on client side browser
lightHttp library also support any browser in the world to quickly and easily make a ajax, pjax, jsonp.
There are two minified JavaScript files with lightHttp function you can use.
One is the "lightHttp.min.js", this file include the promise functions. The flaw of this file is it need 24 KB.
Another one is the "lightHttp-simple.min.js", this file do not include the promise function so it's file size has only 5 KB.
AJAX (GET)
<html>
<script src="lightHttp.min.js"></script>
<script>
var http = new window.lightHttp();
http.ajax("test.html", {"count": 20}, function (content) {
console.log(content);
});
</script>
</html>
AJAX (GET) Promise
<html>
<script src="lightHttp.min.js"></script>
<script>
var http = new window.lightHttp();
http.ajax("test.html", {"count": 20})
.then(function (content) {
console.log(content);
});
</script>
</html>
AJAX (POST)
<html>
<script src="lightHttp.min.js"></script>
<script>
var http = new window.lightHttp();
http.ajaxPost("test.php", {"count": 20}, function (content) {
console.log(content);
});
</script>
</html>
JSONP
<html>
<script src="lightHttp.min.js"></script>
<script>
var http = new window.lightHttp();
http.jsonp("testJsonp.php", {"test":1}, function (resp) {
console.log(resp);
});
</script>
</html>
AJAX (Upload file)
<html>
<script src="lightHttp.min.js"></script>
<input type="file" id="fileInput" />
<script>
var http = new window.lightHttp();
http.addFile("fileData", document.getElementById("fileInput"));
http.ajaxPost("test.php", {"count": 20}, function (content) {
console.log(content);
});
</script>
</html>
