如题：如何获得小程序当目前页面的URL？

自己生成的二维码，要在上面附带参数。假设： 1、二维码上包含的网址为https://123.abc.com.cn 2、想要包含的参数为：data=thisisatestinfo 3、小程序启动页面是index 在index的onLoad中，要接收上面的参数，我是这样写的：   onLoad: function (option) {     console.log(option.data)   } 但返回的是undefined。 请问，问题在哪里？

在小程序里面获得Code后，传到服务端进一步获取OpenID，但报告"Unable to connect to the remote server"错误。 C#代码如下：  string strUrlString = " https://api.weixin.qq.com/sns/jscode2session?appid={0}&secret={1}&js_code={2}&grant_type=authorization_code"; string url = string.Format(strUrlString, strAppID_Xiao, strAppSecret_Xiao, code); GetUsersHelper GetUsersHelper = new GetUsersHelper(); string RequestObj = GetUsersHelper.WXWebRequest(url, string.Empty); …… WXWebRequest方法代码如下： public string WXWebRequest(string posturl, string postData)           {                Stream outstream = null;                Stream instream = null;                StreamReader sr = null;                HttpWebResponse response = null;                HttpWebRequest request = null;                Encoding encoding = Encoding.UTF8;                Log log= new Log(AppDomain.CurrentDomain.BaseDirectory + @"/log/Log.txt");                byte[] data = encoding.GetBytes(postData);                // 准备请求                try                {                     // 设置参数                     request = WebRequest.Create(posturl) as HttpWebRequest;                     CookieContainer cookieContainer = new CookieContainer();                     request.CookieContainer = cookieContainer;                     request.AllowAutoRedirect = true;                     request.Method = "POST";                     request.ContentType = "application/x-www-form-urlencoded";                     request.ContentLength = data.Length;                     outstream = request.GetRequestStream();                     outstream.Write(data, 0, data.Length);                     outstream.Close();                     System.Net.ServicePointManager.DefaultConnectionLimit = 50;                     //发送请求并获取相应回应数据                     response = request.GetResponse() as HttpWebResponse;                     //直到request.GetResponse()程序才开始向目标网页发送Post请求                     instream = response.GetResponseStream();                     sr = new StreamReader(instream, encoding);                     //返回结果网页（html）代码                     string content = sr.ReadToEnd();                     string err = string.Empty;                     response.Close();                     response = null;                     request = null;                     return content;                }                catch (Exception ex)                {                     log.WriteLog("/********WXWebRequest出现错误，错误信息如下： ********/ ");                     log.WriteLog("Class       :" + ex.TargetSite.DeclaringType.Name);                     log.WriteLog("Method      :" + ex.TargetSite.Name);                     log.WriteLog("ErrorMessage:" + ex.Message);                     log.WriteLog("/**************************************************************/");                     return string.Empty;                }          } 服务器的IP已经添加到小程序绑定的那个公众号的IP白名单中去了。 请教问题出在哪里？

我的小程序中，Request调用了一个二级域名，其顶级域名已经备案，这个二级域名没有备案。请问可以吗？

对于这两种用法，一直搞不懂有什么区别。小白一枚，请各位高手指教。谢谢！

新建一个默认的小程序，使用真实的AppID，在app.js的wx.login中添加向后台请求的代码，报告401 Unauthorized错误。代码如下图： [图片] 程序运行输出结果如下图： [图片]
