不允许获取错误方法和内容类型:text/plain

Getting error method not allowed and content-type:text/plain

除了CreateGoal,我的所有路线都运行良好。每当我使用 Post 方法添加数据时,它都会给我消息 method not allowed。当我检查 Get 方法 Headers Content-type 时,它​​是 application/json 但是当我检查 Post 方法 Headers Content-type 时,它​​是 text/plain;字符集=utf-8。所以我觉得肯定是Content-type有问题。我不明白如何解决这个问题。我已附上屏幕截图以供参考。

路线:

func Setup(app *fiber.App) {

    app.Get("/goals", controllers.GetGoals)
    app.Get("/goals/:id", controllers.GetGoal)
    app.Post("/goals/add", controllers.CreateGoal)
    app.Put("/goals/:id", controllers.UpdateGoal)
    app.Delete("/goals/:id", controllers.DeleteGoal)

}

控制器:


import (
    "strconv"
    "github.com/gofiber/fiber/v2"
)

type Goal struct {
  Id        int    `json:"id"`
  Title     string `json:"title"`
  Status        bool   `json:"status"`
}

var goals = []*Goal{
    {
        Id:        1,
        Title:     "Read about Promises",
        Status:         true,
    },
    {
        Id:        2,
        Title:     "Read about Closures",
        Status:         false,
    },
}

func GetGoals(c *fiber.Ctx) error {
    return c.Status(fiber.StatusOK).JSON(
    // "success":  true,
    // "data": fiber.Map{
            // "goals": goals,
        // },
        goals,
  )
}

func CreateGoal(c *fiber.Ctx) error {
    type Request struct {
        Title string `json:"title"`
    }

    var body Request
    err := c.BodyParser(&body)
    if err != nil {
        return c.Status(fiber.StatusBadRequest).JSON(fiber.Map{
            "success": false,
            "message": "Cannot parse JSON",
            "error":   err,
        })
    }

    goal := &Goal{
        Id:        len(goals) + 1,
        Title:     body.Title,
        Status: false,
    }

    goals = append(goals, goal)

    return c.Status(fiber.StatusCreated).JSON(fiber.Map{
        "success": true,
        "data": fiber.Map{
            "goal": goal,
        },
    })
}

您在申请 POST 方法时的端点是 /goals/add。但是在 Postman 中你调用了 /goals

正在申请 /goals 期待 GET 请求。这就是为什么有方法不允许。
