               success : function(data) {
                       alert(data[0][1]);
               },
               error : function(r) {
                       alert("fail");
               }

jsonp returned data is not in the correct format, it should be callback (json) instead of json

from the point of view of the error, it is a syntax error, which does not seem to be the problem of the request, but the problem with the json. Find a website to test the format of this json.
get index? Array method map take all or find take 1

Don't talk too much nonsense, just code.

$.ajax({
          type: "POST",
          url: '/baidu/map/initLink',
          dataType : "json",
          contentType: "application/json;charset=utf-8",
          success: function(data){
              
                  //console.log(data);
                for(var i=0;i<data.length;iPP){
                    var polyline = new BMap.Polyline([
                    new BMap.Point(data[i].callLongitude,data[i].callLatitude),//
                    new BMap.Point(data[i].calledLongitude,data[i].calledLatitude)], //
                    {strokeColor:"green",// 
                    strokeWeight:3, //
                    strokeOpacity:0.5});//
                     map.addOverlay(polyline);    
                }
          }
      });

your data is json, not jsonp,. If the server is not under your control, you will have to figure out a way to get a reverse proxy.
