Question

我正在从我的golang api调用另一个api服务，但是在获取结果时，我的回声c.string响应中附加了一个空值

[{"id":8,"name":null,"description":null,"code":null,"maker":null,"model":null,"duration":null,"maximum_speed":null,"average_speed":null,"maximum_rise_rate":null,"average_rise_rate":null,"maximum_fall_rate":null,"average_fall_rate":null,"turn_rate":null,"camera_angle":null,"moderate_horizontally_speed":null,"moderate_vertical_speed":null,"maximum_horizontally_speed":null,"maximum_vertical_speed":null,"minimum_horizontally_speed":null,"minimum_vertical_speed":null,"key":null,"note":null,"status":true,"deleted":false,"create_date":"2019-05-27T09:47:28.441Z","update_date":"2019-05-27T09:47:28.441Z"}]null <- this null

statusCode, response, err := utils.HTTPGet(utils.AircraftsURL())

    if err != nil && statusCode != 200 {
        return c.String(statusCode, err.Error())
    }

    return c.String(statusCode, response)

这是我的代码，它从已部署的url获取请求

func HTTPGet(url string) (int, string, error) {

    client := &http.Client{
        Timeout: 10 * time.Second,
    }

    req, err := http.NewRequest("GET", url, nil)
    if err != nil {
        log.Fatalf("cannot create a new request GET at HTTPGet = %v", err)
    }

    // req.Header.Set("Content-Type", "application/json")

    res, err := client.Do(req)

    if err != nil {
        log.Fatalf("cannot send a request to the client at HTTPGet = %v", err)
    }

    defer res.Body.Close()

    body, err := ioutil.ReadAll(res.Body)

    return res.StatusCode, string(body), err
}

我的要求是他们的任何问题吗？我不知道为什么将null值附加到我的响应帖子中并得到

来自golang api的响应具有空值响应
