This time I will give you a detailed explanation of the steps for using josnp to receive josn data in ajax. What are the precautions for using josnp to receive josn data in ajax. The following is a practical case, let's take a look.

Recently, I encountered a problem when checking the Express web page. The api of Express 100 was called, but the Express 100 api did not allow cross-domain requests, so 127.0 was used. Requests sent by 0.1 will be intercepted directly.

It’s just a simple web page. I don’t want to do the server forwarding myself, so I finally found a jsonp proxy provided by yahoo:

http://query.yahooapis.com /v1/public/yql

var queryUrl = "\"http://www.kuaidi100.com/query?type=" + $("#type").val() + "&postid=" + $("#postid").val() + "\"";
    $.ajax({
     url: 'http://query.yahooapis.com/v1/public/yql', //jsonp代理api
     dataType: "jsonp",
     data: {
      q: "select * from json where url=" + queryUrl,
      format: "json"
     },
     success: function(result) {
      var res = result.query.results.json;
      console.log(res);
      }
     },
    })
   });
Copy after login
