英文:
GO storing data returns EOF
问题
我是你的中文翻译助手，以下是翻译好的内容：
我是golang的新手，正在尝试构建REST API。到目前为止，GET端点对我来说运行良好，但是我在POST方法（创建用户）方面遇到了困难：
这是我的User结构体的样子：
type User struct {ID uint32 `gorm:"primary_key;auto_increment" json:"id"`Name string `json:"name" binding:"required"`Email string `json:"email" binding:"required"`Password string `json:"password" binding:"required"`CreatedAt time.Time `gorm:"default:CURRENT_TIMESTAMP" json:"created_at"`UpdatedAt time.Time `gorm:"default:CURRENT_TIMESTAMP" json:"updated_at"`}
存储用户的Repo方法：
func CreateUser() (*models.User, error) {var input models.Useruser := models.User{Name: input.Name, Email: input.Email, Password: input.Password}result := Config.DB.Debug().Create(&user)if result.Error != nil {msg := result.Errorreturn nil, msg}return &user, nil}
并从控制器调用：
func CreateUser(c *gin.Context) {//var user models.Useruser := models.User{}user.Prepare()var input models.Usererr := c.BindJSON(&input)if err != nil {c.JSON(http.StatusBadRequest, gin.H{"Error": err.Error(), //this error is thrown})return}userData, err := repo.CreateUser()if err != nil {c.JSON(http.StatusBadRequest, gin.H{"error": err,})return}c.JSON(http.StatusOK, gin.H{"data": userData,})}
我正在使用gorm与数据库进行交互，如果我硬编码输入，例如：
User{Name: "Jinzhu", Email: "test@mail.com", Password: "pass1234"}
那么数据会被存储，但是如果通过Postman传递这些参数，我会收到以下错误：
{"Error":"EOF"}
我已经苦思冥想了几个小时，但仍然不明白错误出在哪里。
英文:
I'm new to golang and I'm trying to build rest api, So far GET endpoints are working for me fine, but I'm having difficulties with POST method(creating user):
That's how my User struct is looking:
type User struct {ID uint32 `gorm:"primary_key;auto_increment" json:"id"`Name string `json:"name" binding:"required"`Email string `json:"email" binding:"required"`Password string `json:"password" binding:"required"`CreatedAt time.Time `gorm:"default:CURRENT_TIMESTAMP" json:"created_at"`UpdatedAt time.Time `gorm:"default:CURRENT_TIMESTAMP" json:"updated_at"`}
Repo method for storing users:
func CreateUser() (*models.User, error) {var input models.Useruser := models.User{Name: input.Name, Email: input.Email, Password: input.Password}result := Config.DB.Debug().Create(&user)if result.Error != nil {msg := result.Errorreturn nil, msg}return &user, nil}
And called from controller:
func CreateUser(c *gin.Context) {//var user models.Useruser := models.User{}user.Prepare()var input models.Usererr := c.BindJSON(&input)if err != nil {c.JSON(http.StatusBadRequest, gin.H{"Error": err.Error(), //this error is thrown})return}userData, err := repo.CreateUser()if err != nil {c.JSON(http.StatusBadRequest, gin.H{"error": err,})return}c.JSON(http.StatusOK, gin.H{"data": userData,})}
I'm using gorm to interact with database and if I'm hardcoding the inputs e.g.
User{Name: "Jinzhu", Email: "test@mail.com", Password: "pass1234"}
Then the data is stored, but if these are passed as parameters via postman, then I'm getting this error:
{"Error":"EOF"}
Been bashing my head for several hours now and still don't understand where's the error.

如mkopriva所指出
c.BindJSON 返回 EOF，这意味着请求中没有发送任何内容
要解决这个问题，你需要在请求体中包含 json，格式应该类似于：
{name: "Jinzhu", email: "test@mail.com", password: "pass1234"}
示例 curl 请求：
curl -X POST localhost:8080 -H 'Content-Type: application/json' --data '{name: "Jinzhu", email: "test@mail.com", password: "pass1234"}'
英文:
As mkopriva pointed
c.BindJSON is returning EOF which means nothing is being sent in request
To solve this you need json in request body which would look something like:
{name: "Jinzhu", email: "test@mail.com", password: "pass1234"}
Example curl request:
curl -X POST localhost:8080 -H 'Content-Type: application/json' --data '{name: "Jinzhu", email: "test@mail.com", password: "pass1234"}'
