小程序开发——统一请求方法

var apiHost = ".....";

//url添加最后的相对路径即可
function getRequest(url, that, targetName) {
  wx.request({
    url: apiHost + url,
    method: ‘GET‘,
    header: {
      ‘content-type‘: ‘application/json‘ // 默认值
    },
    success: function (res) {
      var param = {};
      param[targetName] = res.data;
      that.setData(param);
    },
    fail: function (error) {
      console.log(error);
    }
  })
}

function postRequest(url, data, that, targetName ) {
  var token=‘你的令牌‘;   //比如存储在Storage中
  wx.request({
        url: apiHost + url,
        data: data,
        method: ‘POST‘,
        header: {
            ‘content-type‘: ‘application/json‘, // 默认值
            ‘Authorization‘: "Bearer " + token
