微信小程序接口封装

function baseRequest({ url, method, header, data }, resolve, reject) {
  wx.request({
    url,
    method,
    header,
    data,
    success: function (res) {
      // 需要判断服务器code的用这一段
      // 返回0表示真正的成功,其他code表示各种错误码
      if (res.data.code === 0) {
        resolve(res)
      } else {
        reject(res)
      }
      resolve(res)
    },
    fail: function (res) {
      reject(res)
    }
  })
}

  使用promise

function requestPromise(options) {
  let req = new Promise((resolve, reject) => {
    baseRequest(options, resolve, reject)
  })
  return req
}

  get方法

function get(options) {
  options.method = 'GET'
  return requestPromise(options)
}

  post方法

function post(options) {
  options.method = 'POST'
  if (!options.header) {
    options.header = {}
  }
  options.header["Content-Type"] = "application/json"
  return requestPromise(options)
}

  put方法

function put(options) {
  options.method = 'PUT'
  if (!options.header) {
    options.header = {}
  }
  options.header["Content-Type"] = "application/json"
  return requestPromise(options)
}
