index.js:1警告:错误的道具类型:无效的道具` prop‘类型` of’提供给‘`ForwardRef(阿凡达)’，预期的‘`string`’

Question

我有一个项目，这个项目是关于组织用户的操作，每个用户都有他的帐户的某些设置，从这些设置中他可以点击他的图像(化身)并选择一个图像并将它添加到配置文件帐户中。

但我发现了一个错误：

index.js:1 Warning: Failed prop type: Invalid prop `src` of type `object` supplied to `ForwardRef(Avatar)`, expected `string`.

我该怎么解决呢？

此文件包含添加帐户图片的整个徽标。

profilePage.js：

const useStyles = makeStyles((theme) => ({
  avatar: {
    border: `4px solid ${theme.palette.background.default}`,
  },
  topBg: {
    background: 'url("assets/images/profile/morain-lake.jpg")!important',
    backgroundSize: "cover!important",
    backgroundPosition: "center center!important",
  },
  layoutHeader: {
    background: "none",
    height: 320,
    minHeight: 320,
    [theme.breakpoints.down("md")]: {
      height: 240,
      minHeight: 240,
    },
  },
}));

function ProfilePage() {
  const classes = useStyles();
  const [selectedTab, setSelectedTab] = useState(0);
  const [selectedFile, setSelectedFile] = useState(null);
  function handleTabChange(event, value) {
    setSelectedTab(value);
  }

  const fileSelectHandler = (event) => {
    console.log("beore event");
    setSelectedFile(event.target.files[0]);
    console.log("after event");
  };

  const fileUploadHandler = () => {
    const fd = new FormData();
    fd.append("image", selectedFile, selectedFile.name);
    axios.post("/app-files", fd).then((res) => {
      console.log("res: ", res);
      // onUploadProgress: (ProgressEvent) => {
      //   console.log(
      //     "Upload Progress: " +
      //       Math.round((ProgressEvent.loaded / ProgressEvent.total) * 100) +
      //       "%"
      //   );
      // };
    });
  };

Answer 1

const fileSelectHandler = (event) => {
    console.log("beore event");
    setSelectedFile(event.target.files[0]);
    console.log("after event");
  };

我认为在上面的函数中，event.target.files中有一个对象

您必须在下面的状态示例代码中设置特定的对象属性：

const fileSelectHandler = (event) => {
    const value = event?.target?.files[0]?.name;
    console.log("beore event",value);
    setSelectedFile(()=>value);
    console.log("after event",value);
  };
