WeChat small program network package (simple and efficient)

A nonsense introduction
Although it was born for a long time, it has not been exposed to a small program development. The guitar interest class wants to get a small program to publish course information and card function. As an IT member, I voluntarily joined this small program development team. Although the small procedure is a front-end engineer, it is very friendly as a mobile program, plus a bit of front-end foundation, and it feels very easy.

WeChat applet network request is very convenient, and it can be called directly. But it is best to deal with some parameter callback information, carry out the secondary package, and directly provide the method for the entire small program application to provide a method of adjustment. Isn’t it better?

Using the consistent thinking of the network request, divided into three callbacks: onStart: Start request, onSuccess: request success callback, onfailed: request failure callback, meaning literally ~

Create a netutil.js file


/ ** * For external POST request call * / function post (URL, PARAMS, ONSTART, Onsuccess, onfailed) {Request (URL, PARAMS, “Post”, onstart, onsuccess, onfailed;} / ** * For external GET request call * / Function Get (URL, PARAMS, ONSTART, Onsuccess, onfailed) {Request (URL, Params, “Get”, onstart, onsuccess, onfailed;} / ** * function: Packaging network request * @url URL address * @Params request Parameter * @Method request method: get / post * @OnStart start request, initial loading loading, etc. * @OnSuccess success callback * @onfailed failed callback * / Function Request (URL, Params, Method, onstart, onsuccess, onfailed) {onStart (); // Request Start Wx.Request ({URL: URL, DATA: DEALPARAMS (params), Method: Method, Header: {‘Content-Type’: ‘Application / Json’}, Success: Function (RES) {IF (RES .DATA) {/ ** START processes * / if (res. orerror_code == 0) {onSuccess (res. er); // request success} else {onfailed (res. div); {onfailed . msg); // request failed} / ** END processing end * /}}}} {onfailed (“”); // failure for other reasons}}} / ** * function: Demand Process Request Parameters: Add fixed parameter configuration, etc. * @PARAMS request parameters * / function dealparams (params) {return params;} Module.exports = {PostRequest: post, getRequest: get,}
