jQuery中ajaxPrefilter的应用[设置通用参数]

$.ajaxPrefilter(function (options, originalOptions, jqXHR) { //tm1、tm2表示开始时间、结束时间
  var requestType, params, startTime, endTime;
  requestType = (originalOptions.type || "").toUpperCase(); //jsonp的时候type为undefined
  if (requestType === "GET") {
    params = originalOptions.data ? $.param(originalOptions.data) : originalOptions.url;
  } else if (requestType === "POST") {
    params = $.param(originalOptions.data);
  }
  if (params) {
    startTime = params.match(/(^tm1|&tm1)=([^&#]*)/i) ? decodeURIComponent(params.match(/(^tm1|&tm1)=([^&#]*)/i)[2].replace(/\+/g, "%20")) : null;
    endTime = params.match(/(^tm2|&tm2)=([^&#]*)/i) ? decodeURIComponent(params.match(/(^tm2|&tm2)=([^&#]*)/i)[2].replace(/\+/g, "%20")) : null;
    if (startTime && endTime) {
      startTime = startTime.replace(/\-/g, "/");
      endTime = endTime.replace(/\-/g, "/");
      if (new Date(startTime).getTime() > new Date(endTime).getTime()) {
        jqXHR.abort();
        alert("开始时间不能大于结束时间");
      }
    }
  }
});

let requestSuccessCode = 200;  // 表示请求成功
let tokenName = "accountToken";
$.ajaxSetup({
    // ajax请求之前进行accountToken封装
    beforeSend: function (xhr) {
        if(accountToken && accountToken != '') {
            xhr.setRequestHeader(tokenName, accountToken);
        }
    },
    // ajax 请求完成返回结果
    complete : function(request) {
        if(request.status == 200) {
            let responseCode = request.responseJSON.code;
            if(responseCode == 6001) {
                clearUserCookie();
                let url = window.location.href;
                redirectLogin(url);
            } else if (responseCode == 6002) {
                window.open("/index.html");
            }
        }
    },
    // 表示请求错误
    error :function(request){
        console.info(request);
    }
})
