laravel debugbar 遇到的一个问题

2018-11-19

今天安装开发环境，遇到一个debugbar Illuminate\Contracts\Filesystem\FileNotFoundException 的问题，在Google上搜了好久没找到原因，没办法自己追踪Debugbar源代码看看

看看报错日志

{
    "message": "File does not exist at path /project//storage/debugbar/eyJpdiI6IkY0NHd1Q3Yya0FSMmFnbGp6WVpJUkE9PSIsInZhbHVlIjoiYkhaRTVLVml4allNTGR2cTNnaTVXbDlRdGRzelljWXFBeWF0d0g4QXVsNzBIRUVGY0tKMnVnTUY1ZFFcL3ZSUU4iLCJtYWMiOiI1YTA0ZDdhODgwNGIyNDg4ZDU4OGIwNTcwNzk4MTgzZWJiZDBmNWEzODk3ZGQ3OTdkMTVkMmY4MDU3OTNmZjkxIn0=.json",
    "exception": "Illuminate\\Contracts\\Filesystem\\FileNotFoundException",
    "file": "/project//vendor/laravel/framework/src/Illuminate/Filesystem/Filesystem.php",
    "line": 41,
    "trace": [
        {
            "file": "/project//vendor/barryvdh/laravel-debugbar/src/Storage/FilesystemStorage.php",
            "line": 82,
            "function": "get",
            "class": "Illuminate\\Filesystem\\Filesystem",
            "type": "->"
        },
        {
            "file": "/project//vendor/maximebf/debugbar/src/DebugBar/OpenHandler.php",
            "line": 106,
            "function": "get",
            "class": "Barryvdh\\Debugbar\\Storage\\FilesystemStorage",
            "type": "->"
        },
        {
            "function": "get",
            "class": "DebugBar\\OpenHandler",
            "type": "->"
        },
        {
            "file": "/project//vendor/maximebf/debugbar/src/DebugBar/OpenHandler.php",
            "line": 61,
            "function": "call_user_func"
        },
        ...
    }
}

我们追踪到 /project/vendor/maximebf/debugbar/src/DebugBar/OpenHandler.php 106行看看啥情况

protected function get($request)
{
    if (!isset($request['id'])) {
        throw new DebugBarException("Missing 'id' parameter in 'get' operation");
    }
    return $this->debugBar->getStorage()->get($request['id']);
}

看样子 $request[‘id’] 有问题，然后取不到文件，检查到是handle 方法调用的get

public function handle($request = null, $echo = true, $sendHeader = true)
{
    if ($request === null) {
        $request = $_REQUEST;
    }
}

这里的$request直接取得$_REQUEST,在检查一下COOKIE,GET,POST参数

Cookie: last_session=xxx; XSRF-TOKEN=xxx; id=eyJpdiI6IkY0NHd1Q3Yya0FSMmFnbGp6WVpJUkE9PSIsInZhbHVlIjoiYk

EzODk3ZGQ3OTdkMTVkMmY4MDU3OTNmZjkxIn0%3D!

发现是Cookie里的id覆盖掉了，猜测可能是版本升级的bug之类的吧，没时间去检查官方commit记录，自己临时动手改一下（不推荐直接改底层源码）,将$_REQUEST改成$_GET

1	$request = $_GET;

在Chrome检查请求已正常
