+## config 
+在/config/autoload目录里面创建文件 mongodb.php
+添加以下内容
+```php
+return [
+    'default' => [
+             'username' => env('MONGODB_USERNAME', ''),
+             'password' => env('MONGODB_PASSWORD', ''),

+使用注解，自动加载 
+**\Hyperf\Mongodb\MongoDb** 
+```php
+/**
+ * @Inject()
+ * @var MongoDb
+*/
+ protected $mongoDbClient;
+```
+
+#### **tips:** 
+查询的值，是严格区分类型，string、int类型的哦
+
+### 新增
+
+单个添加
+```php
+$insert = [
+            'account' => '',
+            'password' => ''
+];
+$this->$mongoDbClient->insert('fans',$insert);
+```
+
+批量添加
+```php
+$insert = [
+            [
+                'account' => '',
+                'password' => ''
+            ],
+            [
+                'account' => '',
+                'password' => ''
+            ]
+];
+$this->$mongoDbClient->insertAll('fans',$insert);
+```
+
+### 查询
+
+```php
+$where = ['account'=>'1112313423'];
+$result = $this->$mongoDbClient->fetchAll('fans', $where);
+```
+
+### 分页查询
+```php
+$list = $this->$mongoDbClient->fetchPagination('article', 10, 0, ['author' => $author]);
+```
+
+### 更新
+```php
+$where = ['account'=>'1112313423'];
+$updateData = [];
+
+$this->$mongoDbClient->updateColumn('fans', $where,$updateData); // 只更新数据满足$where的行的列信息中在$newObject中出现过的字段
+$this->$mongoDbClient->updateRow('fans',$where,$updateData);// 更新数据满足$where的行的信息成$newObject
+```
+### 删除
+
+```php
+$where = ['account'=>'1112313423'];
+$all = true; // 为false只删除匹配的一条，true删除多条
+$this->$mongoDbClient->delete('fans',$where,$all);
+```
+
+### count统计
+
+```php
+$filter = ['isGroup' => "0", 'wechat' => '15584044700'];
+$count = $this->$mongoDbClient->count('fans', $filter);
+```
+
+
+
+### Command，执行更复杂的mongo命令
+
+**sql** 和 **mongodb** 关系对比图
+
+|   SQL  | MongoDb |
+| --- | --- |
+|   WHERE  |  $match (match里面可以用and，or，以及逻辑判断，但是好像不能用where)  |
+|   GROUP BY  | $group  |
+|   HAVING  |  $match |
+|   SELECT  |  $project  |
+|   ORDER BY  |  $sort |
+|   LIMIT  |  $limit |
+|   SUM()  |  $sum |
+|   COUNT()  |  $sum |
+
+```php
+
+$pipeline= [
+            [
+                '$match' => $where
+            ], [
+                '$group' => [
+                    '_id' => [],
+                    'groupCount' => [
+                        '$sum' => '$groupCount'
+                    ]
+                ]
+            ], [
+                '$project' => [
+                    'groupCount' => '$groupCount',
+                    '_id' => 0
+                ]
+            ]
+];
+
+$count = $this->$mongoDbClient->command('fans', $pipeline);
+```
