PHP Solr给出了一个致命的致命错误

Question

以下是我的代码，它使用Solr添加文档并触发查询。

显示错误：

SolrInputDocument number 1 is not a valid SolrInputDocument instance
Catchable fatal error: Argument 1 passed to SolrClient::query() must be an instance of SolrParams, string given in /var/www/ps/test.php on line 85

    'spark_plug' => array(
