[ai-proxy] 代理 Gemini 时报错认证失败 #2199
Description
使用 ai-proxy 插件代理 Gemini 服务时报无效的认证凭证错误
ai-proxy 中配置如下
CURL 访问参数如下
curl https://example.com/v1/chat/completions \
-H "Content-Type: application/json" \
-H "Authorization: Bearer ${HIGRESS_API_KEY}" \
-d '{
"messages": [
{
"role": "user",
"content": "Who are you?"
}
],
"model": "gemini-2.0-flash"
}'
{
"error": {
"code": 401,
"message": "Request had invalid authentication credentials. Expected OAuth 2 access token, login cookie or other valid authentication credential. See https://developers.google.com/identity/sign-in/web/devconsole-project.",
"status": "UNAUTHENTICATED"
}
}但是使用同一个 KEY，使用 CURL 调用官方接口是可以正常返回
curl "https://generativelanguage.googleapis.com/v1/models/gemini-2.0-flash:generateContent" \
-H 'Content-Type: application/json' \
-H 'x-goog-api-key: GEMINI_API_KEY' \
-d '{
"contents": [{
"parts":[{"text": "Who are you?"}]
}]
}'
{
"candidates": [
{
"content": {
"parts": [
{
"text": "I am a large language model, trained by Google.\n"
}
],
"role": "model"
},
"finishReason": "STOP",
"avgLogprobs": -3.197540354449302e-05
}
],
"usageMetadata": {
"promptTokenCount": 4,
"candidatesTokenCount": 12,
"totalTokenCount": 16,
"promptTokensDetails": [
{
"modality": "TEXT",
"tokenCount": 4
}
],
"candidatesTokensDetails": [
{
"modality": "TEXT",
"tokenCount": 12
}
]
},
"modelVersion": "gemini-2.0-flash"
}同样使用同一套 KEY， 我切换为 openai 兼容接口，也是可以正常调用
curl https://example.com/v1/chat/completions \
-H "Content-Type: application/json" \
-H "Authorization: Bearer ${HIGRESS_API_KEY}" \
-d '{
"messages": [
{
"role": "user",
"content": "Who are you?"
}
],
"model": "gemini-2.0-flash"
}'
{"choices":[{"finish_reason":"stop","index":0,"message":{"content":"I am a large language model, trained by Google.\n","role":"assistant"}}],"created":1746698000,"model":"gemini-2.0-flash","object":"chat.completion","usage":{"completion_tokens":12,"prompt_tokens":4,"total_tokens":16}}
