配置代理

proxy: {
      '/baiduApi': {
        target: 'https://aip.baidubce.com', //访问地址
        changeOrigin: true,
        secure: false, //只有代理https 地址需要次选项
        pathRewrite: {
          '^/baiduApi': '',
        },
      },
    },

先获取token

//获取百度图片识别的token
      this.axios.get('/baiduApi/oauth/2.0/token?grant_type=client_credentials&client_id=KXBwgOkyn6H&client_secret=32uqmGIdHqD7RcrBRkVRG&',{headers:{
        dataType:'json'
      }}).then(res =>{
        if(res.status ==200){
          this.access_token = res.data.access_token;
        }
      })

拿着上面获取的token去上传文件

<el-upload
              accept="image/png,image/jpg"
              action="contractaches/uoadBatch"
              class="upload-demo"
              drag
              :headers="viewData.myHeaders"
              multiple
              :on-success="handleAvatarSuccess"
            >
              <el-icon
                class="el-icon-upload"
                style="font-size: 40px; margin-top: 40px"
              >
                <upload-filled />
              </el-icon>
              <div class="el-upload__text">
                将文件放在此处或
                <em>点击上传</em>
              </div>
              <template #tip>
                <div class="el-upload__tip">jpg/png 大小小于500kb的文件</div>
              </template>
            </el-upload>

将图片转成base64再切割上传去识别

  const handleAvatarSuccess = (res, file) => {
    console.log(res, file)
    viewData.imageUrl = URL.createObjectURL(file.raw)
    console.log(viewData.imageUrl)

    var fileObj = file.raw
    var reader = new FileReader()
    reader.readAsDataURL(fileObj)
    reader.onload = () => {
      viewData.fileData = reader.result
      viewData.fileData = viewData.fileData.split(',')
      viewData.fileData = viewData.fileData[1]
      var form = new FormData()
      // 文件对象
      form.append('image', viewData.fileData)
      form.append('access_token', viewData.access_token)
      imageExtract(form).then((res) => {
        console.log(res)
      })
    }
  }
