sqler sql 转rest api 数据校验的处理

早期版本（2.0 之前）使用rules 进行数据校验处理，2.0 之后进行了修改使用
validators，这样更加明确

参考格式

 

addpost {

    // if any rule returns false, 

    // SQLer will return 422 code, with invalid rules.

    // 

    // $input is a global variable holds all request inputs,

    // including the http headers too (prefixed with `http_`)

    // all http header keys are normalized to be in this form 

    // `http_x_header_example`, `http_authorization` ... etc in lower case.

    validators {

        post_title_length = "$input.post_title && $input.post_title.trim().length > 0"

        post_content_length = "$input.post_content && $input.post_content.length > 0"

        post_user = "$input.post_user"

    }

​

    bind {

        title = "$input.post_title"

        content = "$input.post_content"

        user_id = "$input.post_user"

    }

​

    exec = <<SQL

        INSERT INTO posts(user_id, title, content) VALUES(:user_id, :title, :content);

        SELECT * FROM posts WHERE id = LAST_INSERT_ID();

    SQL

}
