我收到错误

   {
      "error": {
        "code": 400,
        "message": "Invalid value at 'audio.content' (TYPE_BYTES), Base64 decoding failed for \"ZkxhQwAAACAAA....\"",  

"status": "INVALID_ARGUMENT",
        "details": [
          {
            "@type": "type.googleapis.com/google.rpc.BadRequest",
            "fieldViolations": [
              {
                "field": "audio.content",
                "description": "Invalid value at 'audio.content' (TYPE_BYTES), Base64 decoding failed for \"Zkxh...

当我执行request.sh bash文件时，上述错误会上升。

如何解决此错误？或者其他人有像我这样的问题吗？

看起来你也在Hakernoon尝试过Sara Robinson的代码。

我遇到了同样的问题，this post from ZodiacLeo123帮助了我。

您必须添加“-w”标志

base64 -w 0 audio.flac

这会删除额外的新行。

对于Google Cloud语音API中的\＆＃34; ZKgdjfk .........，Base64解码失败
