Question

我有一个Android应用程序可以获取SSID列表及其信号强度，并返回一个服务器进行分类。我遇到的问题是，建筑物内的某个人（遗憾的是我没有成功找到他们）有一个SSID叫做：

mark anderson's Network

正如您所看到的，他的SSID中有一个'导致服务器程序抛出语法错误：

从应用发送SSID的代码段：

String message = "[" + xTxt.getText().toString() + "," + yTxt.getText().toString() + ",{";
  myWifiMan.startScan();
  List<ScanResult> wifiList = myWifiMan.getScanResults();
  if (wifiList != null){
    //Construct Clue
    for(int i = 0; i < wifiList.size(); i++){
      message = message + "'" + wifiList.get(i).SSID +"':" + Integer.toString(wifiList.get(i).level);
      if((i+1) < wifiList.size())
        message = message + ",";
     }
     message = message + "}]";

来自Python服务器的

片段：

def handle(self):
    udpstring = self.request[0].strip()
    clientid = self.client_address[0]
    input = ast.literal_eval(udpstring)
    xcoord = input[0]
    ycoord = input[1]
    scan = input[2]
    myFile = Settings.trainedFile %(xcoord,ycoord)
    path = os.path.join(Settings.trainedDataFilepath,myFile)

无论如何，我可以让我的程序忽略此SSID或从任何SSID中删除'字符？（来自应用程序或服务器）
