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。以下是尝试的代码：

_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。

看起来此问题已被跟踪了几次，但尚未解决：

终于找到了我的问题。来自ImagePicker的图像的URI在本地应用程序缓存中具有'％'字符。此百分比被URI编码为'％25'，导致putFile代码找不到该文件。在uri周围添加了encodeURI调用即可解决此问题。

let fileUri = decodeURI(pickerResult.uri)

如果您使用的是react-native-document-picker，请检查以下内容： https://github.com/rnmods/react-native-document-picker/issues/235
