uni-request/src/core/dispatchRequest.js

基于Promise封装uni-app的request方法,h5和小程序均可使用

import * as util from '../helpers/util';


export const dispatchRequest = function (config) {

    if (config.baseURL && !util.isAbsoluteURL(config.url)) {
        config.url = util.combineURLs(config.baseURL, config.url);

        config.transformRequest(config.data)

        config.headers[config.method] || {},
        config.headers || {},

    let methods = ['delete', 'get', 'head', 'post', 'put', 'patch', 'common']
    methods.forEach(method => {
        delete config.headers[method];
    });

    let promise = Promise.resolve( config );
    promise = promise.then( config => {
