LSP：无法获取文档符号

Question

我正在学习 LSP，现在正在尝试获取文档符号。我使用 Felix Becker PHP language server。无论我尝试什么，我都无法取回符号。

我已经尝试记录语言服务器接收到的内容，这里是（试图忽略敏感数据）：

{"id":1,"method":"initialize","params":{"initializationOptions":{},"rootUri":"file:\/\/\/Users\/stef\/Projects\/TestApp","capabilities":{},"rootPath":"\/Users\/stef\/Projects\/TestApp","trace":"verbose","processId":null,"workspaceFolders":[{"uri":"file:\/\/\/Users\/stef\/Projects\/TestApp","name":"TestApp"}]},"jsonrpc":"2.0"}
{"id":2,"method":"initialized","params":{},"jsonrpc":"2.0"}
{"id":3,"method":"textDocument\/didOpen","params":{"textDocument":{"uri":"file:\/\/\/Users\/stef\/Projects\/TestApp\/models\/User.php","languageId":"php","version":1,"text":"<?php\n\nnamespace app\models;\n\nuse Yii;\n\n\/**\n * This is the model class for table \"Users\".\n *\n * @property integer $id\n * @property string $User\n * @property integer $route\n * @property string $bus\n * @property string $start\n * @property string $end\n * @property string $dept_date\n * @property string $dept_time\n * @property integer $customer\n * @property integer $issued_on\n * @property string $machine_serial\n * @property integer $price\n * @property integer $is_deleted\n * @property string $OOOPS\n * @property integer $expired_in\n * @property integer $created_at\n * @property integer $created_by\n * @property integer $updated_at\n * @property integer $updated_by\n *\n * @property PlannedRoutes $deptDate\n * @property Buses $bus0\n * @property Customers $customer0\n * @property Stops $end0\n * @property POSes $machineSerial\n * @property Routes $route0\n * @property Stops $start0\n *\/\nclass User extends TenantModel\n{\n    use \app\traits\Signature;\n\n    const OOOPS_KOOK = 'BO';\n    const OOOPS_TEMPORARY_KOOK = 'BT';\n    const OOOPS_CANCELLED = 'CA';\n    const OOOPS_CONFIRMED = 'CO';\n    const OOOPS_FOOF_User = 'CT';\n    const OOOPS_FREE = 'FR';\n    \n    public $RWF;\n    public $UGS;\n    public $FIB;\n    public $USD;\n    public $seats; \/\/ total bus seats\n    public $Users; \/\/ sold Users\n    public $bookings; \/\/ valid bookings\n    public $promotion; \/\/ Promotion Users\n    public $staff; \/\/ Staff Users\n    public $location; \/\/ Staff Location\n    public $day; \/\/ User day like Monday\n    public $author; \/\/ Staff who created User\n    public $broute; \/\/ Main Route\n    \n    public $FOOFs; \/\/total FOOFs sold\n    public $crevenue; \/\/total FOOFs Revenue\n    \/**\n     * @inheritdoc\n     *\/\n ....some sensitive data omitted...}}},"jsonrpc":"2.0"}

{"id":4,"method":"textDocument\/documentSymbol","params":{"textDocument":{"uri":"file:\/\/\/Users\/stef\/Projects\/TestApp\/models\/User.php"}},"jsonrpc":"2.0"}

这是来自服务器的记录响应

很多{"method":"window\/logMessage","params"....
很多{"method":"textDocument\/publishDiagnostics"...

终于得到

{"result":null,"id":3,"jsonrpc":"2.0"}Content-Type: application/vscode-jsonrpc; charset=utf8
Content-Length: 36

我找不到服务器不响应符号的原因。我尝试了同一作者的 VS 插件，它工作正常，这意味着我在某个地方搞砸了。但不能只是想出来！

感谢任何帮助。

碰巧我的 JSON RPC 负载包含未转义的 0x09 或制表符控制字符。用\t替换它解决了问题
