请帮助我解决此问题,我尝试了很多,并花了最后两天的时间来解决它,但不明白为什么它无法连接。
I try to configure yii2-mongodb on my project, installed it using composer, then add 我尝试在我的项目上配置yii2-mongodb,使用composer安装它,然后添加
in config/web.php 在config / web.php中
'mongodb' => [
'class' => '\yii\mongodb\Connection',
'dsn' => 'mongodb://user:password@insta1-shard-00-00-s0vxe.mongodb.net:27017,insta1-shard-00-01-s0vxe.mongodb.net:27017,insta1-shard-00-02-s0vxe.mongodb.net:27017/database?ssl=true&replicaSet=Insta1-shard-0&authSource=admin',
]
and use this model: 并使用此模型:
<?php
namespace app\models;
use Yii;
use yii\base\Model;
use yii\mongodb\Query;
/**
* BlogContent is the model behind the contact form.
*/
class BlogContent extends Model
{
public function getPostList($page) {
$query = new Query();
// compose the query
$rows = $query->select(['name', 'price', 'title'])
->from('services')->all();
}
}
it should return me all documents from the collection, but it returns to me this stack: 它应该返回集合中的所有文档,但是会返回此堆栈:

I solve this first issue by passing a $db connection to query as an optional argument, but it can't connect anyway. 我通过将$ db连接作为可选参数传递给查询来解决第一个问题,但是无论如何它都无法连接。 Also, I test connection to MongoDB on my local machine - for a single database it works as need.
另外,我在本地计算机上测试到MongoDB的连接-对于需要运行的单个数据库。
问题是因为我的php-mongodb与php7发生冲突,所以在我更新后,所有这些都开始按需工作。
