在 PostgreSQL 中,我有一个名为surveys.
CREATE TABLE SURVEYS(
SURVEY_ID UUID PRIMARY KEY NOT NULL DEFAULT uuid_generate_v4(),
SURVEY_NAME VARCHAR NOT NULL,
SURVEY_DESCRIPTION TEXT,
START_PERIOD TIMESTAMP,
END_PERIOD TIMESTAMP
);
如您所见,只有SURVEY_ID和SURVEY_NAME列是NOT NULL.
在 Go 中,我想根据请求在该表中创建新条目POST。我像这样发送 JSON 对象:
{
"survey_name": "NAME",
"survey_description": "DESCRIPTION",
"start_period": "2019-01-01 00:00:00",
"end_period": "2019-02-28 23:59:59"
}
不幸是,它引发了奇怪的错误:
parsing time ""2019-01-01 00:00:00"" as ""2006-01-02T15:04:05Z07:00"": cannot parse " 00:00:00"" as "T"
我在哪里犯了错误以及如何解决我的问题?
模型/surveys.go:
import (
"database/sql"
"time"
)
type NullTime struct {
time.Time
Valid bool
}
type Survey struct {
ID int `json:"survey_id"`
Name string `json:"survey_name"`
Description sql.NullString `json:"survey_description"`
StartPeriod NullTime `json:"start_period"`
EndPeriod NullTime `json:"end_period"`
}
控制器/surveys.go:
var CreateSurvey = func(responseWriter http.ResponseWriter, request *http.Request) {
// Initialize variables.
survey := models.Survey{}
var err error
// The decoder introduces its own buffering and may read data from argument beyond the JSON values requested.
err = json.NewDecoder(request.Body).Decode(&survey)
if err != nil {
log.Println(err)
utils.ResponseWithError(responseWriter, http.StatusInternalServerError, err.Error())
return
}
手掌心
