React Native Firebase存储上载因未知错误而失败

Question

我正在使用react-native-firebase与我们的Firebase帐户一起使用身份验证,防火墙和存储.尝试将照片上传到存储失败,出现未知错误.这是尝试的代码:

_pickImage = async () => {
  await this.getCameraRollPermission()
  let result = await ImagePicker.launchImageLibraryAsync({
    allowsEditing: true,
    aspect: [4, 3],
  });

  console.log(result);

  if (!result.cancelled) {
    // this.setState({ photoURL: result.uri });
    this._handlePhotoChoice(result)
  }
};

_handlePhotoChoice = async pickerResult => {
  let userId = this.state.userId
  firebase
    .storage()
    .ref('photos/profile_' + userId + '.jpg')
    .putFile(pickerResult.uri)
    .then(uploadedFile => {
      console.log("Firebase profile photo uploaded successfully")
    })
    .catch(error => {
      console.log("Firebase profile upload failed: " + error)
    })
}

在iOS模拟器中测试并使用调试器来检测错误我刚刚收到此错误:

"Error: An unknown error has occurred.

更新:

文件上传到存储桶,但该文件不是JPEG照片,而是有关该文件的JSON内容:

{"contentType":"image\/jpeg","name":"photos\/profile_XPIO2lHjlYbdLPchACZHBsmY9Jr1.jpg"}

所以不知何故,一个JSON文件最终在桶中而不是实际的照片中,然后抛出错误.

看起来这个问题被跟踪了几次,但没有解决:

终于找到我的问题了。ImagePicker 中图像的 URI 中包含来自本地应用程序缓存的“%”字符。该百分比被 URI 编码为“%25”，这导致 putFile 代码找不到该文件。在 uri 周围添加decodeURI 调用解决了该问题。

let fileUri = decodeURI(pickerResult.uri)
