# MongoDB 操作工具包
|
||
用于操作MongoDB，简化开发流程。要使用此工具包，你的MongoDB**必须已经开启访问控制**。
|
||
|
||
## 使用方法
|
||
### 连接数据库
|
||
|
||
```go
|
||
var mongodb = am_mongo.MongoDB{
|
||
Host: "127.0..0.1",
|
||
Port: "27017",
|
||
Username: "root",
|
||
Password: "1234567"
|
||
}
|
||
|
||
err := mongodb.Connect("testdb")
|
||
|
||
defer am_mongo.Close()
|
||
```
|
||
|
||
### 创建Model和唯一索引
|
||
```go
|
||
type User struct {
|
||
Name string `bson:"name"`
|
||
Age int `bson:"age"`
|
||
Email string `bson:"email"`
|
||
}
|
||
|
||
mongodb.CreateUniqueIndex("testCollection", "email")
|
||
```
|
||
|
||
### CRUD
|
||
#### 插入
|
||
```go
|
||
var user = User{
|
||
Name: "Joe Biden",
|
||
Age: 82,
|
||
Email: "heyjoebiden@gmail.com"
|
||
}
|
||
err := mongodb.Insert("testCollection", &user)
|
||
```
|
||
|
||
#### 查询
|
||
```go
|
||
// 条件查询
|
||
var filter = bson.M{"email": "heyjowbiden@gmail.com"}
|
||
var results []User
|
||
|
||
err := mongodb.Find("testCollection", filter, &results)
|
||
|
||
// 全数查询
|
||
err = mongodb.Find("testCollection", bson.M{}, &results)
|
||
```
|
||
|
||
#### 修改
|
||
```go
|
||
var filter = bson.M{"email": "heyjowbiden@gmail.com"}
|
||
var update = bson.M{"name": "Donald J Trump"}
|
||
err := mongodb.Update("testCollection", filter, update)
|
||
```
|
||
|
||
#### 删除
|
||
```go
|
||
var filter = bson.M{"email": "heyjowbiden@gmail.com"}
|
||
err := mongodb.Delete(filter)
|
||
``` |
