Swagger如何描述JSON请求体参数

Swagger How to describe JSON body parameter

问题

我正在尝试为我的 Rest API(Gin 框架)添加文档,并在尝试构建 JSON 请求体参数时遇到了一些问题。

目前,我有以下 API 描述操作:

// @Summary logins a user
// @ID 		login-user
// @Accept 	json
// @Produce	json
// @Param   email 		formData string true "user email"
// @Param   password 	formData string true "user password"
// @Success 200 {object} gin.H	"login response"
// @Failure 400 {object} gin.H	"error response"
// @Router 	/login [post]
func (server *Server) handleLoginUser() gin.HandlerFunc {
	return func(ctx *gin.Context) {
		var req loginUserRequest
		if err := ctx.ShouldBindJSON(&req); err != nil {
			ctx.JSON(http.StatusBadRequest, utils.ErrorResponse(err))
			return
		}

        // 一些代码

		ctx.JSON(http.StatusOK, response)
	}
}

当我通过 Swagger UI 提交数据时,我收到以下错误:

{
"error": "invalid character 'e' looking for beginning of value"
}

此外,这是生成的 cURL 命令:

curl -X 'POST' \
  'http://localhost:8080/api/login' \
  -H 'accept: application/json' \
  -H 'Content-Type: application/json' \
  -d 'email=my%40email.com&password=password'

值得一提的是,当我在 Postman 中使用原始 JSON 请求体提交相同的数据时,它可以正常工作。这是一个典型的 JSON 示例(也是 loginUserRequest):

{
   "email": "my@mail.com",
   "password": "password"
}

由于我对 Swagger 还不熟悉,我相信问题与 Swagger 的 [attribute documentation] 中定义的 emailpassword 参数类型有关。

那么,我应该如何更好地描述 loginRequest 的 JSON 请求体呢?

英文:

I am trying to add documentation to my Rest API (Gin framework) and I stepped in some problems while trying to structure a JSON body parameter.

Currently, I have the following API description operations:

// @Summary logins a user
// @ID 		login-user
// @Accept 	json
// @Produce	json
// @Param   email 		formData string true "user email"
// @Param   password 	formData string true "user password"
// @Success 200 {object} gin.H	"login response"
// @Failure 400 {object} gin.H	"error response"
// @Router 	/login [post]
func (server *Server) handleLoginUser() gin.HandlerFunc {
	return func(ctx *gin.Context) {
		var req loginUserRequest
		if err := ctx.ShouldBindJSON(&req); err != nil {
			ctx.JSON(http.StatusBadRequest, utils.ErrorResponse(err))
			return
		}

        // some code

		ctx.JSON(http.StatusOK, response)
	}
}

When I submit the data through Swagger UI I get the following error:

{
"error": "invalid character 'e' looking for beginning of value"
}

Also, this is the generated cURL:

curl -X 'POST' \
  'http://localhost:8080/api/login' \
  -H 'accept: application/json' \
  -H 'Content-Type: application/json' \
  -d 'email=my%40email.com&password=password'

It's worth to mention that whenever I submit the same data in Postman with body Raw JSON it works. This is what a usual JSON looks like (also, loginUserRequest):

{
   "email": "my@mail.com",
   "password": "password"
}

Since I am new to Swagger, I am pretty sure it's something related to the email & password param type defined on the Swagger's [attribute documentation].

So, how should I describe better the loginRequest JSON body?

答案1

得分: 5

这很容易,但我猜他们在文档中省略了这一部分。我只是按照以下方式更改了参数:

// @Param   loginUserRequest body loginUserRequest true "user password"

然后,在运行 swag init --parseDependency --parseInternal --parseDepth 1 时它就可以工作了。

英文:

It was pretty easy, but I guess they omitted that in the documentation. I just changed the parameter as following:

// @Param   loginUserRequest body loginUserRequest true "user password"

And then, when running swag init --parseDependency --parseInternal --parseDepth 1 it works.
