自学微信小程序从零到一项目构建后的 HTTP 请求封装技巧

wx.request({

  url: 'test.php', //仅为示例，并非真实的接口地址

  data: {

    x: '',

    y: ''

  },

  header: {    'content-type': 'application/json' // 默认值

  },

  success (res) {

    console.log(res.data)

  }

})

/**

 *

 * @param {String} url

 * @param {Object} data

 * @param {String} method

 * @param {String} header

 */

function request(url, data={}, method='GET', header="Content-Type: application/json",) {

    return new Promise(function (resolve, reject) {

        wx.request({

            url: url,

            data: data,

            header: header,

            method: method,

            dataType: 'json',

            responseType: 'text',

            success: (res)=>{

                if(res.statusCode === 200) {

                    if (res.data.code === 200) {

                        resolve(res.data)

                    } else {

                        wx.showToast({

                            title: res.data.msg,

                            icon: 'none',

                            image: '',

                            duration: 1500,

                            mask: false,

                            success: (result)=>{

                                resolve(res.data);

                            },

                        });

                    }

                } else {

                }

            },

            fail: (res)=>{

                // 需要我们加上统一的错误处理代码

                reject(res)

            },

            complete: ()=>{}

        });

    })

}

// 封装方法

// 如果对于header有什么特殊的要求，可以在请求参数里面做一些添加，例如后续我们会在headder中加入我们的sessionkey这些内容

// header = {}里面添加header内容

// 这块是一个简版的说明

const header = {

    "Content-Type": "application/json",

    // 这个token是微信登录以后，将token存入在缓存中

    "token": "*****************"

}

const get = function(url, data, header) {

    return request(url, data, 'GET', header);

    return request(url, data, 'POST', header);

const del = function(url, data, header) {

    return request(url, data, '', header);

    get,

    post,

    del,

webHttp.get(api.user.info, {

    // nick_name:

    ...self.globalData.userInfo
