微信小程序网络封装(简单高效)

/
  供外部post请求调用
 /
function post(url, params, onStart, onSuess, onFailed) {
 request(url, params, "POST", onStart, onSuess, onFailed);
}

/
  供外部get请求调用
 /
function get(url, params, onStart, onSuess, onFailed) {
 request(url, params, "GET", onStart, onSuess, onFailed);
}

/
  function: 封装网络请求
  @url URL地址
  @params 请求参数
  @method 请求方式GET/POST
  @onStart 开始请求,初始加载loading等处理
  @onSuess 成功回调
  @onFailed 失败回调
 /
function request(url, params, method, onStart, onSuess, onFailed) {
 onStart(); //request start
 wx.request({
 url: url,
 data: dealParams(params),
 method: method,
 header: { 'content-type': 'application/json' },
 suess: function (res) {
  if (res.data) {
  / start 根据需求 接口的返回状态码进行处理 /
  if (res.data.error_code == 0) {
   onSuess(res.data); //request suess
  } else {
   onFailed(res.data.msg); //request failed
  }
  / end 处理结束/
  }
 },

 fail: function (error) {
  onFailed(""); //failure for other reasons
 }
 })
}

/
  function: 根据需求处理请求参数添加固定参数配置等
  @params 请求参数
 /
function dealParams(params) {
 return params;
}

 postRequest: post,
 getRequest: get,
