小程序 之同步请求

一、代码

//request通用
const request = (url, param, method = 'get', dataType = 'json', responseType = 'text') => {
  var method = method.toLowerCase()
  return new Promise((resolve, reject) => {
    if (method == 'get') {
      var header = {
        'content-type': 'application/json'
      }
    } else if (method == 'post') {
      var header = {
        'content-type': 'application/x-www-form-urlencoded'
      }
    }else{
      reject('header is error')
    }
    wx.request({
      url: url,
      data: param,
      header: header,
      method: method,
      dataType: dataType,
      responseType: responseType,
      success(res) {
        console.log(res)
        resolve(res.data)
      },
      fail(err) {
        console.log(err)
        reject(err)
      }
    })
  })
}

// request get 请求
const getData = (url, param) => {
  return new Promise((resolve, reject) => {
    wx.request({
      url: url,
      method: 'GET',
      data: param,
      success(res) {
        console.log(res)
        resolve(res.data)
      },
      fail(err) {
        console.log(err)
        reject(err)
      }
    })
  })
}

// request post 请求
const postData = (url, param) => {
  return new Promise((resolve, reject) => {
    wx.request({
      url: url,
      method: 'POST',
      data: param,
      success(res) {
        console.log(res)
        resolve(res.data)
      },
      fail(err) {
        console.log(err)
        reject(err)
      }
    })
  })
}

// loading加载提示
const showLoading = () => {
  return new Promise((resolve, reject) => {
    wx.showLoading({
      title: '加载中...',
      mask: true,
      success(res) {
        console.log('显示loading')
        resolve(res)
      },
      fail(err) {
        reject(err)
      }
    })
  })
}

// 关闭loading
const hideLoading = () => {
  return new Promise((resolve) => {
    wx.hideLoading()
    console.log('隐藏loading')
    resolve()
  })
}

module.exports = {
  request,
  getData,
  postData,
  showLoading,
  hideLoading
}
