Google Cloud SDK cURL cloud 無法解析蓋主機

Question

我正在尝试在Windows上设置Google Cloud API。我花了很多时间来解决这个问题，阅读所有相关问题没有任何帮助！ 首先我设置变量

set GOOGLE_APPLICATION_CREDENTIALS="C:UsersDesktopdirectoryfilename.json"
curl -H "Authorization: Bearer "$(gcloud auth application-default print-access-token) 
-H "Content-Type: application/json; charset=utf-8" 
--data "{
'input':{
'text':'Android is a mobile operating system developed by Google,
based on the Linux kernel and designed primarily for
touchscreen mobile devices such as smartphones and tablets.'
},
'voice':{
'languageCode':'en-gb',
'name':'en-GB-Standard-A',
'ssmlGender':'FEMALE'
},
'audioConfig':{
'audioEncoding':'MP3'
}
}" "https://texttospeech.googleapis.com/v1/text:synthesize" > synthesize-text.txt

如谷歌文档中所述。但在命令行中

卷曲：(6( 云未解析主机：身份验证 curl：(6( 云未解析主机：应用程序默认值 curl：(6( 云未解析主机：打印访问令牌

显示此错误。在合成文本中.txt说错误代码 401。

我该如何解决这个问题。任何帮助赞赏。

编辑： 当我原谅

gcloud auth 应用程序默认的打印访问令牌命令

返回环境变量不存在时！但是 ı 执行设置命令。我做错了什么？

Answer 1

这是由于Windows不接受$(gcloud auth application-default print-access-token)使用。

您可以尝试将打印访问令牌的命令输出写入文件。例如：

gcloud auth application-default print-access-token > token.txt

然后，您可以将其分配给环境变量：

set /p token=<token.txt

并尝试像这样运行文本到语音转换 API 请求：

curl -H "Authorization: Bearer "%token% 
-H "Content-Type: application/json; charset=utf-8" 
--data "{
'input':{
'text':'Android is a mobile operating system developed by Google,
based on the Linux kernel and designed primarily for
touchscreen mobile devices such as smartphones and tablets.'
},
'voice':{
'languageCode':'en-gb',
'name':'en-GB-Standard-A',
'ssmlGender':'FEMALE'
},
'audioConfig':{
'audioEncoding':'MP3'
}
}" "https://texttospeech.googleapis.com/v1/text:synthesize" > synthesize-text.txt

或者，您可以尝试对请求使用 API 密钥。例如：

curl -H "Content-Type: application/json; charset=utf-8"  
--data "{ 
'input':{ 
'text':'Android is a mobile operating system developed by Google, 
based on the Linux kernel and designed primarily for 
touchscreen mobile devices such as smartphones and tablets.' 
}, 
'voice':{ 
'languageCode':'en-gb', 
'name':'en-GB-Standard-A', 
'ssmlGender':'FEMALE' 
}, 
'audioConfig':{ 
'audioEncoding':'MP3' 
} 
}" "https://texttospeech.googleapis.com/v1/text:synthesize?key=YOUR_API_KEY" > synthesize-text.txt
