Laravel：与Postgres一起使用Laravel Passport时的QueryException

Question

• Laravel版本：5.5.0
• PHP版本：PHP 7.1.7-1 + ubuntu16.04.1 + deb.sury.org + 1（cli）（建于：2017年7月7日09:41:45）（NTS）
• 数据库驱动程序＆amp;版本：psql（PostgreSQL）9.5.7

说明

使用Laravel Passport时，我在使用oauth令牌时收到以下错误作为响应：

Illuminate \ Database \ QueryException (22P02)
SQLSTATE[22P02]: Invalid text representation: 7 ERROR: invalid input syntax for integer: "" (SQL: select * from "users" where "id" = limit 1)

我也opened an issue on the passport repo但这似乎是一个可能与框架本身有关的问题，即Postgres驱动程序。从这个问题的其他报告中读取（见下文），似乎有一个参数没有正确格式化，因此没有添加到查询中（where "id" = limit 1不包括实际在=之后的ID。我认为框架以某种方式将此值作为字符串接收，而不是整数。因此，查询格式失败。有没有人有这方面的解决方案，或者至少知道错误可能存在的地方？

其他报道似乎是同一个问题

• https://github.com/laravel/framework/pull/18364
• https://github.com/laravel/passport/issues/54
• https://github.com/laravel/passport/issues/311

重现步骤：

1. 配置Postgres数据库驱动程序
2. 按照Laravel网站上的文档设置Passport
3. 生成一个oauth令牌（我使用Postman）
4. 在请求中使用此令牌
