Golang curl 找不到接受参数'\'的位置参数

如何解决Golang curl 找不到接受参数'\'的位置参数

我正在根据 golang 网站的教程制作一个基本的 golang 应用程序，并将最终代码粘贴到此处。

package main

import (
    "net/http"

    "github.com/gin-gonic/gin"
)

// album represents data about a record ablum
type album struct {
    ID     string  `json:"id"`
    Title  string  `json:"title"`
    Artist string  `json:"artist"`
    Price  float64 `json:"price"`
}

// albums slice to seed record album data.
var albums = []album{
    {ID: "1",Title: "Blue Train",Artist: "John Coltrane",Price: 56.99},{ID: "2",Title: "Jeru",Artist: "Gerry Mulligan",Price: 17.99},{ID: "3",Title: "The Suburbs",Artist: "Arcade Fire",Price: 39.99},}

//getAlbums response with the list of all albums as JSON
func main() {
    router := gin.Default()
    router.GET("/albums",getAlbums)
    router.GET("/albums/:id",getAlbumByID)
    router.POST("/albums",postAlbums)

    router.Run("localhost:8081")
}

func getAlbums(c *gin.Context) {
    c.IndentedJSON(http.StatusOK,albums)
}

func postAlbums(c *gin.Context) {
    var newAlbum album

    // Call BindJSON to bind the received JSON to
    // newAlbum.
    if err := c.BindJSON(&newAlbum); err != nil {
        return
    }

    // Add the new album to the slice.
    albums = append(albums,newAlbum)
    c.IndentedJSON(http.StatusCreated,newAlbum)
}

// getAlbumByID locates the album whose ID value matches the id
// parameter sent by the client,then returns that album as a response.
func getAlbumByID(c *gin.Context) {
    id := c.Param("id")

    // Loop over the list of albums,looking for
    // an album whose ID value matches the parameter.
    for _,a := range albums {
        if a.ID == id {
            c.IndentedJSON(http.StatusOK,a)
            return
        }
    }
    c.IndentedJSON(http.StatusNotFound,gin.H{"message": "album not found"})
}

它将专辑存储在内存中。我正在尝试使用 POST 请求，通过在 powershell 中使用 curl 命令来添加新专辑。这是添加项目函数：https://golang.org/doc/tutorial/web-service-gin#add_item

我的问题是当我运行 curl 命令添加新专辑时，如文章所述，它给了我以下消息：

Invoke-WebRequest：找不到接受参数“”的位置参数。 在行：1 字符：1

• curl http://localhost:8081/albums \ --include \ --header "Content-Typ ...

•   + CategoryInfo          : InvalidArgument: (:) [Invoke-WebRequest],ParameterBindingException
    + FullyQualifiedErrorId : PositionalParameterNotFound,Microsoft.PowerShell.Commands.InvokeWebRequestCommand
  
  

我该怎么做才能获得添加新专辑的 POST 请求？
