我是 Go 新手并使用 gin 框架尝试创建用户对象：

const (
    // CollectionArticle holds the name of the users collection
    CollectionUser = "users"
)


// User table contains the information for each user
type User struct {
    ID  bson.ObjectId `json:"_id,omitempty" bson:"_id,omitempty"`
    Username string        `json:"username" bson:"username"`
    Email     string        `json:"email" bson:"email"`
    Password  string        `json:"password" bson:"password"`
    StatusID  uint8         `json:"status_id" bson:"status_id"`
    CreatedAt time.Time     `json:"created_at" bson:"created_at"`
    UpdatedAt time.Time     `json:"updated_at" bson:"updated_at"`
    Deleted   uint8         `json:"deleted" bson:"deleted"`
}

这是创建用户的控制器

// Create a user
func Create(c *gin.Context) {
    db := c.MustGet("db").(*mgo.Database)

    //to help debugging
    x, _ := ioutil.ReadAll(c.Request.Body)
    log.Printf("request body is: %s \n", string(x)) 

    user := models.User{}
    err := c.Bind(&user)
    if err != nil {
        c.Error(err)
        return
    }

    //to help debugging
    log.Printf("user is: %v", user )
    log.Printf("username is: %s and emails is %s", user.Username, user.Email )  

    err = db.C(models.CollectionUser).Insert(user)
    if err != nil {
        c.Error(err)
    }
    c.Redirect(http.StatusMovedPermanently, "/users")
}

登记表是：

  <form action="/user/create" method="POST">


    <div class="form-group">
      <label for="username">Username</label>
      <input type="text" name="username" class="form-control" id="username" placeholder="Enter the username of the user" >
    </div>

    <div class="form-group">
      <label for="email">Email</label>
      <input name="email" class="form-control" placeholder="Enter user email" />
    </div>

    <div class="form-group">
    <label for="password">Password</label>
        <input type="password" name="password" class="form-control" placeholder="Password" required>
    </div>

    <button type="submit" class="btn btn-default">Submit</button>

  </form>

在终端我得到：

[GIN-debug] Listening and serving HTTP on :7000
[GIN] 2016/04/25 - 06:30:04 | 200 |     549.499µs | 127.0.0.1 |   GET     /register
request body is: username=bob&email=bob%40me.com&password=1234 
user is: {ObjectIdHex("")    0 0001-01-01 00:00:00 +0000 UTC 0001-01-01 00:00:00 +0000 UTC 0}
username is:  and emails is

如您所见username，字段值email被password传递给控制器​​。当我检查usersmongo 数据库中的集合时，我看到对象已创建但从表单提交的字段为空。我无法弄清楚为什么会发生这种情况，所以感谢您的提示。

根据 gin 文档，您需要form标记来构造字段。喜欢：

User     string `form:"user" binding:"required"`
Password string `form:"password" binding:"required"`
