this.$axios({       method: 'post',       url: 'http://www.17huo.com/tusou/deeplorSearch.html',       headers: {         'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8'       },       data: { imgFile: url },       params: { imgFile: url }     }).then(data => {       console.log(data)     })

data和params都必须传递，最好还是让后端设置支持application/json
