You called this URL via POST, but the URL doesn‘t end in a slash and you have APPEND

1、报错信息

RuntimeError: You called this URL via POST, but the URL doesn't end in a 
slash and you have APPEND_SLASH set. Django can't redirect to the slash 
URL while maintaining POST data. Change your form to point to 
localhost:8000/save_user_detail/ (note the trailing slash), orset 
APPEND_SLASH=False in your Django settings.

 2、定位问题：axios中的post请求未以 ‘/’ 结尾

 methods:{
            save_user_detail(){
                axios.post('http://localhost:8000/save_user_detail',this.form_data).then(res=>{
                    this.$message({
                        message:'保存成功',
                        type:'success',
                    })
                })

            },
}

3、解决方案：在axios中的请求末尾，增加 '/'后。

        methods:{
          save_user_detail(){
              axios.post('http://localhost:8000/save_user_detail/',this.form_data).then(res=>{
                  this.$message({
                      message:'保存成功',
                      type:'success',
                  })
              })
          },
}

4、前端打包后，调用该接口，接口返回成功。
