beego中自动参数处理中的错误

Question

我无法在beego中使用自动参数处理，这是我的代码

const realNumberArray = [4, 5.6, -9.8, 3.14, 42, 6, 8.34];
const squareList = (arr) => {
    "use strict";

    const squaredIntegers = (arr) => {
        let arrayChoosen = arr.filter(ele => ele > 0 && Number.isInteger(ele));
        return arrayChoosen.map(x => x * x);
    }

    return squaredIntegers(arr);
};
// test your code
const squaredIntegers = squareList(realNumberArray);
console.log(squaredIntegers);

当我从python请求发送请求时

ns := beego.NewNamespace("/api",beego.NSAutoRouter(&controllers.DevicesController{}))

type DevicesController struct {
    beego.Controller
}

func (c *DevicesController) FuncTest(id int, field string) {
    c.Data["json"] = map[string]interface{}{"status": "ok", "message": "Automatic parameter Success"}
    c.ServeJSON()
}

我遇到以下错误

requests.post("http://localhost:8080/api/devices/functest?id=5&field=test")
