前端页面报错，后端没有收到数据，如何解决？

Question

前端的数据好像没有传到后端去，后端接口测试正确，怎么解决啊，实在看不懂

```html

<template>
  <el-row>
    <el-col :span="24" class="bc">
      <div class="bCenter">
        <el-tabs type="border-card" class="nav-bc">
          <el-tab-pane label="添加每日一句">
            <div class="grid-content bg-purple-light">
              <div class="bcc">
                <el-form

      var dbj=JSON.stringify(bj)
      //console.log(dbj)
      this.$http.post('/ky/user/addoneword',dbj).then(result => {
                console.log(result.body)
                if(result.body.message!=null){
                   this.$message.success(result.body.message)
                }
            })
    }

Answer 1

500是因为请求传到了后端，但是后端程序运行出了异常。
从postman的结果来看，后端程序是想要从你请求query中获取参数，而你在使用这个接口的时候，将参数放入了请求体（body）中，并且你的参数中还多了个operation(当然。这个如果后端做的好，忽略了也没问题）。所以后端处理异常。
修改建议：

this.$http.post(`/ky/user/addoneword?author=${this.oneWord.author}&content=${this.oneWord.content}`).then(result => {
                console.log(result.body)
                if(result.body.message!=null){
                   this.$message.success(result.body.message)
                }
            })
