ruoyi 上传头像Current request is not a multipart request

一、前言

        都知道，我们在写项目的时候，最想给自己项目增加实用性了，例如我们的头像上传以及个人的各种信息等等。我们刚刚已经做好了我们的上传接口，那么我们现在就趁热打铁，将我们的头像上传功能解决一下。

二、个人信息界面

        我们的个人信息界面由我们的头像以及我们的表格组成，那么就说明我们需要去获取我们用户的数据了

        我们之前是做过用户数据存储的，就是利用token来将我们用户的数据存放在我们的浏览器里面，然后利用localStorage来查找出我们的用户数据。

三、头像上传 

对于头像上传，我们依然用到我们之前的接口和组件来实现该功能。

        </el-form-item>

    </el-card>
  </div>
</template>

<script>

export default {
  name: "Person",
  data() {
    return {
      form: {},
      user: localStorage.getItem("user") ? JSON.parse(localStorage.getItem("user")) : {},
      options: [{
        value: '男',
        label: '男'
      }, {
        value: '女',
        label: '女'
      }],
      value: ''
    }
  },
  mounted() {

    // 获取地理位置
    var geolocation = new BMapGL.Geolocation();
    geolocation.getCurrentPosition(function(r){
      if(this.getStatus() == BMAP_STATUS_SUCCESS){
        const province = r.address.province
        const city = r.address.city
        localStorage.setItem("location", province + city)
      }
    });
  },

  created() {
    this.load()
  },
  methods: {
    load() {
      const username = this.user.username
      if (!username) {
        this.$message.error("当前无法获取用户信息!请登录!")
        return
      }
      this.request.get("/user/username/" + username).then(res => {
        // console.log(res)
        this.form = res.data
      })
    },
    sign() {
      const location = localStorage.getItem("location")
      const username = this.user.username

      this.request.post("/sign", { user: username, location: location }).then(res => {
        if (res.code === '200') {
          this.$message.success("打卡成功")
        } else {
          this.$message.error(res.msg)
        }
      })
    },
    save() {
      this.request.post("/user", this.form).then(res => {
        if (res.data) {
          this.$message.success("保存成功")
          this.load()

          this.$emit('refreshUser')
        } else {
          this.$message.error("保存失败")
        }
      })
    },
    // 头像上传
    handleAvatarSuccess(res) {
      // res就是头像文件路径
      this.form.avatarUrl = res
    },
  }
}
</script>

<style>
.avatar-uploader {
  text-align: left;
  padding-bottom: 10px;
}
.avatar-uploader .el-upload {
  border: 1px dashed #d9d9d9;
  border-radius: 6px;
  cursor: pointer;
  position: relative;
  overflow: hidden;
}
.avatar-uploader .el-upload:hover {
  border-color: #409EFF;
}
.avatar-uploader-icon {
  font-size: 28px;
  color: #8c939d;
  width: 138px;
  height: 138px;
  line-height: 138px;
  text-align: center;
}
.avatar {
  width: 160px;
  height: 160px;
  display: block;
}
</style>

四、头部Header使用

        我们在我们的头部进行数据查询和引用，就是通过user，然后找到我们的头像的元素，最后进行展示 

        我们需要在我们的脚手架里面去获取用户User最新的数据，然后最后在我们的头部Header里面去进行引入并获取信息 

源码：

 

<template>
  <div style="display: flex; line-height: 60px">
    <div style="flex: 1">
      <span :class="collapseBtnClass" style="cursor: pointer; font-size: 18px"></span>
      <el-breadcrumb separator="/" style="display: inline-block; margin-left: 10px">
        <el-breadcrumb-item :to="'/mall/index'" >主页</el-breadcrumb-item>
        <el-breadcrumb-item >{{ currentPathName }}</el-breadcrumb-item>
      </el-breadcrumb>
    </div>

    <el-dropdown style="width: 130px; cursor: pointer">

      <div style="display: inline-block; float: right; margin-right: 10px">
        <img :src="user.avatarUrl" alt=""
             style="width: 30px; border-radius: 50%; position: relative; top: 10px; right: 5px">
        <span>{{user.nickname}}</span><i class="el-icon-arrow-down" style="margin-left: 5px"></i>
      </div>

      <el-dropdown-menu slot="dropdown" style="width: 100px; text-align: center">
        <el-dropdown-item style="font-size: 14px; padding: 5px 0">
          <span style="text-decoration: none" @click="person">个人信息</span>
        </el-dropdown-item>
        <el-dropdown-item style="font-size: 14px; padding: 5px 0">
          <span style="text-decoration: none" @click="logout">退出登录</span>
        </el-dropdown-item>
      </el-dropdown-menu>

    </el-dropdown>

  </div>
</template>

<script>
export default {
  name: "Header",
  props: {
    collapseBtnClass: String,
    user: Object
  },
  computed: {
    currentPathName () {
      return this.$store.state.currentPathName;　　//需要监听的数据
    }
  },
  data() {
    return {
      user: localStorage.getItem("user") ? JSON.parse(localStorage.getItem("user")) : {}
    }
  },
  methods: {
    logout() {
      this.$router.push("/login")
      this.$message.success("退出成功")
    },
    person(){
      this.$router.push("/mall/person")
    }
  }
}
</script>

<style scoped>

</style>
