我们用sureness来管理restful api认证鉴权

面对 restful api 的认证鉴权,基于 rbac (用户-角色-资源)主要关注于对 restful api 的安全保护
无特定框架依赖(本质就是过滤器处拦截判断,已有springboot,quarkus,javalin,ktor等demo)
支持动态修改权限配置(动态修改哪些api需要被认证，可以被谁访问)
支持主流http容器 servlet 和 jax-rs
支持多种认证策略, jwt, basic auth, digest auth … 可扩展自定义支持的认证方式
基于改进的字典匹配树拥有的高性能 良好的扩展接口, demo和文档
sureness的低配置，易扩展，不耦合其他框架，能使开发者对自己的项目多场景快速安全的进行保护

i guess the exception may happen in this code:

        // If request URL is greater than 2048 characters, use POST method.
        if (url.length > 2048) {
            delete data.q;
            requestOptions = [
                `${baseUrl}?${querystring.stringify(data)}`,
                {
                    method: "POST",
                    form: true,
                    body: {
                        q: text
                    }
                }
            ];
        }
```
the post method access google api may be can not use form when body is json.

Hope to help!

Just change from:

form: true,
body: {
    q: text
}

To:

form: {
    q: text
}

And then it should work

       let options = {
          method: 'POST',

const res = await got(options)

This is my code. Would you let me know what is wrong, please?
