Google Cloud SDK cURL cloud not resolve host - json

Question

I am trying to setup Google Cloud Api on windows. I spend many hours to fix this issue read all related questions nothing helps!
First I set the variable
set GOOGLE_APPLICATION_CREDENTIALS="C:\Users\Desktop\directory\filename.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
As describe in google documentation. But in command line
curl: (6) cloud not resolve host: auth
curl: (6) cloud not resolve host: application-default
curl: (6) cloud not resolve host: print-access-token
Show me this error. In synthesize-text.txt says that error code 401.
How can I fix this. Any help appreciate.
Edit:
When I excuse the gcloud auth application-default print-acces-token command
Returns Environment variable does not exist! But ı excute the set command. What am I doing wrong ?

Answer 1

This is due to windows doesn't accept the $(gcloud auth application-default print-access-token) usage.
You can try writing the command output for the print-access-token to a file. For instance:
gcloud auth application-default print-access-token > token.txt
Then you can assign this to an environment variable:
set /p token=<token.txt
And try running your Text-to-Speech API request like this:
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
Alternatively, you can try using the API Keys for your requests. For instance:
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
