Node. js generates the HttpStatusCode auxiliary class and publishes it to npm.

Source: Internet
Author: User

As a good Restfull Api, it is not only about the semantics, readability, power, and orthogonal of service URLs, but also about http Status codes. A good Http Status Code gives users a good response, for example, 200 indicates normal success, 201 indicates successful creation, 409 conflict, and 404 resource does not exist. Therefore, we are working on a node-based architecture. node is found in js + mongodb + angularjs demo. js express does not provide the corresponding auxiliary classes, but I do not like to fill the 201,404 class of things without hierarchical semantics everywhere, so I finally decided to write it myself, but I am also very lazy, what should I do if I do not like repeated hard work? Copy the code from the HttpStatusCode enumeration in c #, which I am most familiar with. In the end, node is used for mac convenience. js parses msdn documentation on httpstatuscode to generate node. js helper class.

The code is simple:

Copy codeThe Code is 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 generation class is:

Copy codeThe Code is as follows:
View Code
Exports. httpStatusCode = {
"Continue": 100,
"SwitchingProtocols": 101,
"OK": 200,
"Created": 201,
"Accepted": 202,
"Nonauthoritativeinfo": 203,
"NoContent": 204,
"ResetContent": 205,
"PartialContent": 206,
& Quot; MultipleChoices & quot;: 300,
"Ambiguous": 300,
"MovedPermanently": 301,
"Moved": 301,
"Found": 302,
"Redirect": 302,
"SeeOther": 303,
"RedirectMethod": 303,
"NotModified": 304,
"UseProxy": 305,
"Unused": 306,
"TemporaryRedirect": 307,
"RedirectKeepVerb": 307,
"BadRequest": 400,
"Unauthorized": 401,
"PaymentRequired": 402,
"Forbidden": 403,
"NotFound": 404,
"MethodNotAllowed": 405,
"NotAcceptable": 406,
"ProxyAuthenticationRequired": 407,
"RequestTimeout": 408,
"Conflict": 409,
"Gone": 410,
"LengthRequired": 411,
"PreconditionFailed": 412,
"RequestEntityTooLarge": 413,
"RequestUriTooLong": 414,
"UnsupportedMediaType": 415,
"RequestedRangeNotSatisfiable": 416,
"ExpectationFailed": 417,
"UpgradeRequired": 426,
"InternalServerError": 500,
"NotImplemented": 501,
"BadGateway": 502,
"ServiceUnavailable": 503,
"GatewayTimeout": 504,
"HttpVersionNotSupported": 505
};

Finally, considering that there may be a lot of people who are as lazy as I do, sharing this code to npm can be simple and practical. Here is a test demo:

Copy codeThe Code is 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 articles are always redundant texts in the code. I hope the code can describe everything. Thank you for reading this article.
