我有興趣創建一個httptest.Server簡單地記錄調用它的請求。為此，我想使用該github.com/matryer/moq庫。為了生成一個模擬http.Handler，我將它的定義復制到一個名為的包中client：package clientimport "net/http"type Handler interface {    ServeHTTP(http.ResponseWriter, *http.Request)}然后我跑了moq -out handler_mock.go . Handler在client目錄中，它產生了以下內容handler_mock.go：// Code generated by moq; DO NOT EDIT.// github.com/matryer/moqpackage clientimport (    "net/http"    "sync")var (    lockHandlerMockServeHTTP sync.RWMutex)// Ensure, that HandlerMock does implement Handler.// If this is not the case, regenerate this file with moq.var _ Handler = &HandlerMock{}// HandlerMock is a mock implementation of Handler.////     func TestSomethingThatUsesHandler(t *testing.T) {////         // make and configure a mocked Handler//         mockedHandler := &HandlerMock{//             ServeHTTPFunc: func(in1 http.ResponseWriter, in2 *http.Request)  {//                 panic("mock out the ServeHTTP method")//             },//         }////         // use mockedHandler in code that requires Handler//         // and then make assertions.////     }type HandlerMock struct {    // ServeHTTPFunc mocks the ServeHTTP method.    ServeHTTPFunc func(in1 http.ResponseWriter, in2 *http.Request)    // calls tracks calls to the methods.    calls struct {        // ServeHTTP holds details about calls to the ServeHTTP method.        ServeHTTP []struct {            // In1 is the in1 argument value.            In1 http.ResponseWriter            // In2 is the in2 argument value.            In2 *http.Request        }    }}以制作具有模擬處理程序函數的測試服務器？
