hello, there is no "project" concept if i use google account login to gemini cli, which value I should config for it?
hello, there is no "project" concept if i use google account login to gemini cli, which value I should config for it?
thanks, 我用的是普通google账号登陆，不是workspace账号登陆呢。
那么这个时候，这个project我填啥？
普通google账号登陆
那就不填参数, 保持原样, 不填不行再看如下
注意需要保证gemini code可以正常使用
项目 ID是需要参考在projectcreate设置或者把已设置好的ID复制过来，注意是项目ID不是项目编号也不是项目名
hello, there is no "project" concept if i use google account login to gemini cli, which value I should config for it?
When you first sign in to gemini-cli using your Google account, it automatically creates a dedicated Google Cloud project to manage API access. You'll need the Project ID of this project for configuration.
Here’s how to find it:
- Navigate to the Google Cloud Console Go to the Google Cloud Console.
- Open the Project Selector At the top of the page, click on the project dropdown menu.
- Identify and Select Your Project In the "Select a project" window, look for a project with a randomly generated name. Projects created by
gemini-clitypically have a unique, multi-part name (e.g.,inlaid-hydra-rlk9u). Select that project from the list. - Copy the Project ID After selecting the project, you will be taken to its dashboard. Locate the Project info card and click the copy icon next to the Project ID.

Hi there, is there any config.example.json can let me do the settings right? I can't get it done.
@billzhuang Hi, do you have config.json for me to refer to? thx

This is my config.json but please check the warning i notice during using this tool, when i'm looking for solution i see open issue about this warning, and after i examine the code found this solution and wait for the dev to check this issue and fix it:

transformer 使用 gemini 和 gemini-cli有什么区别呀? 有点没理解?
配置gemini-cli 他对应的 "api_base_url": "https://cloudcode-pa.googleapis.com/v1internal", 是固定的吗?
this thing contains a hard-coded client_id and client_secret which is a significant security risk...
@anthrotype The client_id and client_secret fields are also hardcoded in gemini-cli itself. That's why I think it's normal, or even good. Otherwise, it would be more difficult to use their API.

Oh, didn't know that, thanks for clarifying
Hey there, can GeminiCLITransformer handle multi-account rotation? Is there a way to use the quota of multiple accounts simultaneously? How is the quota limit implemented for Gemini CLI? I tried multi-account rotation, but the actual available quota was only that of a single account. However, those accounts in Gemini CLI can still access Gemini-2.5-Pro, which is a bit confusing.
使用免费账户尝试，transformers的project必须填写，否则会报错。
{
"path": "$HOME/.claude-code-router/plugins/gemini-cli.js",

"project": "your_project_id**"
}
},
此外，Providers中，api_base_url填两个都可以：
https://cloudcode-pa.googleapis.com/v1internal
或者
https://generativelanguage.googleapis.com/v1beta/models/

这样配置依旧不行，会爆出404错误，且无法解决

插件的路径似乎不能写$HOME，不会自动展开，要写完整的路径。
接口 rate limit 怎么处理啊
