How to Wrap GET Requests with Parameters in WeChat Mini Programs

The author explains that to avoid duplicating request code in a WeChat Mini Program, a custom GET request wrapper should be created. The wrapper combines a global base URL with a specific endpoint, passes query parameters, sets the appropriate JSON content‑type header, and provides callbacks for success and failure.

// GET request wrapper with parameters
function getDataForParam(url, params, doSuccess, doFail) {
  wx.request({
    url: app.globalData.req_url + url,
    data: params,
    header: {
      "content-type": "application/json;charset=UTF-8"
    },
    method: 'GET',
    success: function (res) {
      doSuccess(res.data);
    },
    fail: function () {
      doFail();
    },
  })
}
