The data given by the background has data:image/jpg;base64,

Insert picture description here

    getBase64(base64) {
      var changebase64 = base64.replace(/[\r\n]/g, "");
      console.log(changebase64);
      return changebase64;
    },
    // Experimental report 
    getreport(id) {
      getAppLabExaminationInfo(id).then((res) => {
        if (res.code == 200) {
        //res.data.filePath  Backstage base64 data 
          this.imgurl=this.getBase64(res.data.filePath);
          this.dialogVisible2 = true;
        }
      });
    },

If there is no return data , Use this

 getBase64(base64) {
      var changebase64 =
        "data:image/jpg;base64," + base64.replace(/[\r\n]/g, "");
      console.log(changebase64);
      return changebase64;
    },
