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，JSON文件最终在桶中而不是实际照片中，然后抛出错误 .
看起来这个问题被跟踪了几次，但没有解决：

终于找到了我的问题 . 来自ImagePicker的图像的URI在本地应用缓存中具有'％'字符 . 这个百分比被URI编码为'％25'，导致putFile代码找不到该文件 . 在uri周围添加decodeURI调用修复了问题 .
