我正在為一個(gè)寧?kù)o的 api 編寫單元測(cè)試，并希望確保得到預(yù)期的響應(yīng)。如何去掉預(yù)期字符串文字末尾的“\n”？我正在使用 stethr 的 testify 包。我曾嘗試使用字符串 TrimSuffix、TrimRight 函數(shù)，但沒(méi)有成功。func TestGetConfig(t *testing.T) {    testServer := initTestServer(t)    req, err := http.NewRequest("GET", "/api/config", nil)    if err != nil {    t.Fatal(err)    }    rr := httptest.NewRecorder()    handler := http.HandlerFunc(testServer.getConfig)    handler.ServeHTTP(rr, req)    //Check the status code is what we expect    if status := rr.Code; status != http.StatusOK {    t.Errorf("handler returned wrong status code: got %v want %v", status, http.StatusOK)    }    //Check the response body is what we expect. expected := `{"domain":"","ip":"","redirect_key":"mj","redirect_url":"https://www.youtube.com/watch?v=dQw4w9WgXcQ","verification_key":"yp","verification_token":"5a62"}`    expected = strings.TrimSuffix(expected, "\n")    assert.Equal(t, rr.Body.String(), expected)}我希望測(cè)試能夠通過(guò)，但它卻失敗了，并將其作為輸出。Error Trace:    config_test.go:94                    Error:          Not equal:                                    expected: "{\"domain\":\"\",\"ip\":\"\",\"redirect_key\":\"mj\",\"redirect_url\":\"https://www.youtube.com/watch?v=dQw4w9WgXcQ\",\"verification_key\":\"yp\",\"verification_token\":\"5a62\"}\n"                                    actual  : "{\"domain\":\"\",\"ip\":\"\",\"redirect_key\":\"mj\",\"redirect_url\":\"https://www.youtube.com/watch?v=dQw4w9WgXcQ\",\"verification_key\":\"yp\",\"verification_token\":\"5a62\"}"
