按照微信提供的生成带参数的小程序码后，小程序上线。扫描生成的带参数的小程序码，为啥不进入指定的页面还是进入到小程序的首页呢？是需要配置什么吗？

URL url = new URL("https://api.weixin.qq.com/wxa/getwxacodeunlimit?access_token=" + accessToken);

HttpURLConnection httpURLConnection = (HttpURLConnection) url.openConnection();

httpURLConnection.setRequestMethod("POST");// 提交模式

httpURLConnection.setRequestProperty("Content-Type", "application/json");

// httpURLConnection.setConnectTimeout(90000);//连接超时 单位毫秒

// httpURLConnection.setReadTimeout(2000);//读取超时 单位毫秒

// 发送POST请求必须设置如下两行

httpURLConnection.setDoOutput(true);

httpURLConnection.setDoInput(true);

// 获取URLConnection对象对应的输出流

PrintWriter printWriter = new PrintWriter(httpURLConnection.getOutputStream());

// 发送请求参数

JSONObject paramJson = new JSONObject();

paramJson.put("scene", sceneStr);

paramJson.put("path", xcxUrl);

paramJson.put("width", 120);

//paramJson.put("auto_color", true);

paramJson.put("auto_color", false);

JSONObject lineColor = new JSONObject();

lineColor.put("r", 0);

lineColor.put("g", 0);

lineColor.put("b", 0);

paramJson.put("line_color", lineColor);

printWriter.write(paramJson.toString());

// flush输出流的缓冲

printWriter.flush();

// 开始获取数据

BufferedInputStream bis = new BufferedInputStream(httpURLConnection.getInputStream());
