goActions

goActions定义

static void exampleAction(Webs *wp)
{
    const char *io_val;
    io_val = websGetVar(wp, "val_led", nullptr); // 获取POST过来的数据
    qDebug() << "on_led_set: " << io_val;

    websSetStatus(wp, 200);
    websWriteHeaders(wp, -1, nullptr);
    websWriteEndHeaders(wp);
    websWrite(wp, "%s", "<h4>hello GoAction!</h4>"); // 返回数据
    websDone(wp);
    return nullptr;
/****这句注册一个可以通过action/exampleGetAction访问的GoAction函数****/
websDefineAction("exampleAction", exampleGetAction);
