微信小程序

1. request数据请求封装

import http from '../libs/request/index.js'

export const httpUrl="https://xx.xxx.xx";
//设置请求配置
http.setConfig({
    baseUrl: httpUrl
})



export const wxLogin=data=>http.get('/api/Public/FlowerLoginWeixin',data);

1. 调用

import deepMerge from "../function/deepMerge";


let config = {
    baseUrl: '', // 请求的根域名
    // 默认的请求头
    header: {
        'content-type': 'application/json;charset=UTF-8'
    },
    method: 'GET',
    // 设置为json，返回后uni.request会对数据进行一次JSON.parse
    dataType: 'json',
    // 此参数无需处理，因为5+和支付宝小程序不支持，默认为text即可
    responseType: 'text'
}

// 主要请求部分
async function request(options = {}) {

    options.dataType = options.dataType || config.dataType;
    options.responseType = options.responseType || config.responseType;
    options.url = options.url || '';
    options.data = options.data || null;
    options.header = Object.assign(config.header, options.header);
    options.method = options.method ||config.method;
    
    console.log(options.header);

    return new Promise((resolve, reject) => {
        
        options.complete = (response) => {
            if (response.statusCode == 200) {
                //返回请求数据
                resolve(response.data);
            }else if(response.statusCode == 401){
                console.log("清楚缓存，重新授权");
                wx.clearStorage({
                    success(){
                        wx.redirectTo({
                            url: '/pages/login/login'
                        })
                    }
                })
            }else {
                console.error(options);
                //直接接入catch回调
                reject(response)
            }
        };
        //根据请求判断是否需要加上域名
        options.url=options.url.indexOf('http') == 0 ?options.url:config.baseUrl+options.url;
        console.log(options.url);
        wx.request(options);
    })

}

const http = {
    // 设置全局默认配置
    setConfig(customConfig) {
        // 深度合并对象，否则会造成对象深层属性丢失
        config = deepMerge(config, customConfig);
    },
    ajax(options={}){
        return request(options)
    },
    // get请求
    get(url, data = {}, header = {}){
        return request({
            method: 'GET',
            url,
            header,
            data
        })
    },
    // post请求
    post(url, data = {}, header = {}){
        return request({
            url,
            method: 'POST',
            header,
            data
        })
    }
}
