如何用ajax和codeigniter解决400（错误请求）错误

Question

I am getting a 400 (Bad Request) error with ajax and codeigniter

this is my ajax call

$.ajax({
            type: "POST",
            url: '<?php echo base_url(); ?>query/sensor/'+ test + / + past  + / + id + / + port + / + device,

            success: function(res) {
            if (res)
            {

                console.log("res"+res);
                    }
            }
            });


      }

is it a proper ajax url?

Answer 1

• First Make sure you get variables values test, past ....

• You can change url: 'query/sensor/'+ test + / + past + / + id + / + port + / + device,

  With this url:

url: 'query/sensor/'+ test +'/' + past + '/' + id + '/' + port + '/' + device,
