Node.js Generate HttpStatusCode Secondary class publishing to Npm_ basics

As a good Restfull API is not only in the service URL semantics, readability, power, orthogonal, as an HTTP status code is also very important, a good HTTP state code to the user a good response, such as 200 for normal success, 201 means to create a successful , 409 conflicts, 404 resources do not exist, and so on. So in doing a demo based on Node.js+mongodb+angularjs found that Node.js Express did not provide the corresponding auxiliary class, but I do not like to 201,404 of these languages without language level of the meaning of the full, So finally decided to write one, but at the same time I am also very lazy, do not like to do repetitive coolie live, how to do? Copy it from the HttpStatusCode enumeration in my most familiar C #, and finally use the Node.js to parse MSDN's HttpStatusCode document generation Node.js for simplicity on the Mac.

The code is simple:

Copy Code code as follows:

var http = require (' http ');

var fs = require (' FS ');

var $ = require (' jquery ');

var output = "Httpstatuscode/index.js";

(function () {



String.Format = function () {

var s = arguments[0];

for (var i = 0; i < arguments.length-1; i++) {

var reg = new RegExp ("\\{" + i + "\}", "GM");

s = S.replace (Reg, arguments[i + 1]);

}

return s;

};




var options = {

Host: ' msdn.microsoft.com ',

PORT:80,

Path: '/zh-cn/library/system.net.httpstatuscode.aspx '

};




Http.get (options,function (response) {

var html = "";

Response.on ("Data", function (chunk) {

HTML + chunk;

). On (' End ', function () {

Handler (HTML);

}. On (' Error ', function (e) {

Console.log ("Got error:" + e.message);

});




function Gethttpstatuscode (htmlstring) {

var $doc = $ (HTML);

var rows = $doc. Find ("Table#memberlist tr:gt (0)");

var status = {};

Rows.each (function (i,row) {

status[$ (Row). Find ("Td:eq (1)"). Text ()] =

parseint ($ (row). Find ("Td:eq (2)"). Text (). Match (/\d+/). toString ());

});

return status;

};



function Generatecode (status) {

var code = "";

Code + + "Exports.httpstatuscode =" + json.stringify (status) + ";";

return code;

};



function WriteFile (code) {

Fs.writefile (output, code, function (ERR) {

if (err) {

Console.log (ERR);

} else {

Console.log ("The file was saved" + Output + "!");

}

});

};




function handler (HTML) {

var status = Gethttpstatuscode (HTML);

var code = Generatecode (status);

WriteFile (code);

};




});

})();

The final generated class is:

Copy Code code as follows:

Exports.httpstatuscode = {
"Continue": 100,
"Switchingprotocols": 101,
"OK": 200,
"Created": 201,

"Httpversionnotsupported": 505
};

Finally, considering that there may be a lot of lazy people like me, so share this code posted to NPM, only the NPM install HttpStatusCode, it can be simple and practical, the following is a test demo:

Copy Code code as follows:

var HttpStatusCode = require ("HttpStatusCode"). HttpStatusCode;

var tobeequal = function (actual,expected) {

if (actual!== expected) {

Throw (actual + "Not equal" + expected);

}

};

Tobeequal (httpstatuscode.ok,200);

Tobeequal (httpstatuscode.created,201);

Tobeequal (httpstatuscode.badrequest,400);

Tobeequal (httpstatuscode.internalservererror,500);




Console.log (HttpStatusCode);

Console.log ("Success");

Lazy person's article is always code redundant text, hope the code can explain everything, thank you for reading.
