如何在 gin 的测试上下文中设置主机？

Question

我想为控制器编写单元测试，但我不断收到运行时错误。我发现这是由于没有Host关于请求、ClientIP()方法和请求正文的。如何在测试上下文中设置它们？这是我到目前为止得到的。它与Host: c.Request.Host.控制器：type loggingControllers struct {    LoggingService services.InterfaceLogging}func (l *loggingControllers) RegisterError(c *gin.Context) {    errorEvent := models.Error{        Badges:    map[string]string{},        Host:      c.Request.Host,        ClientIP:  c.ClientIP(),        UserAgent: c.Request.UserAgent(),        Count:     1,        Timestamp: time.Now().Unix(),    }    err := json.NewDecoder(c.Request.Body).Decode(&errorEvent)    if err != nil {        utils.RespondWithError(c, http.StatusInternalServerError, err.Error())        return    }    go l.LoggingService.SaveError(errorEvent)    utils.RespondWithSuccess(c)}func GetLoggingControllerMock() loggingControllers {    loggingServiceMock := services.GetLoggingServiceMock()    return loggingControllers{        LoggingService: &loggingServiceMock,    }}单元测试：func TestLoggingControllers(t *testing.T) {    loggingControllers := GetLoggingControllerMock()    w := httptest.NewRecorder()    c, _ := gin.CreateTestContext(w)    loggingControllers.RegisterError(c)}错误信息：--- FAIL: TestLoggingControllers (0.00s)panic: runtime error: invalid memory address or nil pointer dereference [recovered]    panic: runtime error: invalid memory address or nil pointer dereference[signal SIGSEGV: segmentation violation code=0x1 addr=0x38 pc=0x15238ec]

我找到了解决方案。

func TestLoggingControllers(t *testing.T) {

    loggingControllers := GetLoggingControllerMock()

    w := httptest.NewRecorder()

    c, r := gin.CreateTestContext(w)

    r.POST("/", loggingControllers.RegisterError)

    c.Request, _ = http.NewRequest(http.MethodPost, "/", bytes.NewBuffer([]byte("{}")))

    r.ServeHTTP(w, c.Request)

    if w.Code != http.StatusOK {

        t.Errorf("Expected status %d, got %d", http.StatusOK, w.Code)

    }

}
