Question

我尝试将图片上传到Firebase。我正在使用'react-native-image-picker'，但每次我都会收到错误。 Firebase存储：字符串与格式'base64'不匹配：找到无效字符。我看到许多帖子与此问题相关，但没有一个正在发挥作用。

uploadImage = response = >
{
    let metadata = {
        contentType: response.type
    }
    let randomId = shortid.generate()
    let fileExtension
    if (Platform.OS == "android") fileExtension = response.type.split("/")[1]
    else
    {
        fileExtension = response.fileName.split(".")[1]
    }
    let storagePath =
        "/Base_Url/" +
        this.props.username +
        "/" +
        this.props.sessionId +
        "/" +
        randomId +
        "." +
        fileExtension
    let storingRef = firebase.storage()
        .ref(storagePath);
    storingRef.putString(response.data, "base64url", metadata)
        .on(
            firebase.storage.TaskEvent.STATE_CHANGED,
            snapshot = >
            {
                var progress =
                    snapshot.bytesTransferred / snapshot.totalBytes * 100;
                if (progress === 100)
                {
                    let downloadURL = FireBaseUtils.getDownloadURL(storagePath);
                    this.setState(
                    {
                        url: snapshot.downloadURL
                    });
                }
                else
                {
                    switch (snapshot.state)
                    {
                    case firebase.storage.TaskState.PAUSED:
                        break;
                    case firebase.storage.TaskState.RUNNING:
                        break;
                    }
                }
            },
            error = >
            {
                switch (error.code)
                {
                case "storage/unauthorized":
                    break;
                case "storage/canceled":
                    break;
                case "storage/unknown":
                    break;
                }
            }
    );
};

尝试使用putString(message, 'base64')（不是base64url）

如果Blob，File或Uint8Array不可用，您可以使用 putString（）方法上传raw，base64，base64url或data_url 编码字符串到云存储。

希望有所帮助

字符串与格式'base64'不匹配：找到无效字符，并且当前只能从其他Blob创建Blob本地响应
