"txtSearchType=1" +
//                              这是输入的地方 问题时输入字母可以 输入汉字或者是特殊字符就查不到我想要的结果
"&txtTm=" + new String(text.getString().getBytes("GBK"),"ISO-8859-1")+

求问 该怎么解决 

Answer 1

requeststring = "hidWxlx=spanCNLx" +
"&nMaxCount=100" +
"&nSetPageSize=10" +
"&txtLx=%" +
"&txtPY=HZ" +
"txtSearchType=1" +
// 这是输入的地方 问题时输入字母可以 输入汉字或者是特殊字符就查不到我想要的结果
"&txtTm=" + URLEncoder.encode(text, "UTF-8")+
"&txtWxlx=CN";获取值的时候 
再URLDecoder.decode(text, "UTF-8");试试

public void run(){
String url =  "http://192.168.118.200/wxjs/tmjs.asp";
String requeststring = null;
try {
requeststring = "hidWxlx=spanCNLx" +
"&nMaxCount=100" +
"&nSetPageSize=1" +
"&txtLx=%" +
"&txtPY=HZ" +
"txtSearchType=1" +

"&txtTm=" + text.getString().getBytes("gbk")+

"&txtWxlx=CN";
} catch (UnsupportedEncodingException e2) {
e2.printStackTrace();
}
OutputStream osm = null;
HttpConnection hc = null;
System.out.println(requeststring);
try{
hc = (HttpConnection) Connector.open(url);
hc.setRequestMethod(HttpConnection.POST); 
}catch(IOException e1){ }
try{
hc.setRequestMethod(HttpConnection.POST); 
hc.setRequestProperty("X-Online-Host","192.168.118.200");
hc.setRequestProperty("User-Agent","Profile/MIDP-2.0 Configuration/CLDC-1.1");
hc.setRequestProperty("Content-Language","en-US");
hc.setRequestProperty("Content-Type","application/x-www-form-urlencoded");
hc.setRequestProperty("Accept","application/octet-stream");
hc.setRequestProperty("Connection","Keep-Alive");
hc.setRequestProperty("Content-Length",Integer.toString(requeststring != null?requeststring.length() : 0 ) );  
osm = hc.openOutputStream();
System.out.println("连接成功。。");
DataOutputStream dos = new DataOutputStream(osm);
System.out.println("发送请求中。。");
byte[] b1 = requeststring.getBytes();
for(int i=0;i<b1.length;i++){
osm.write( b1[i]);
}
dos.close(); DataInputStream dis = hc.openDataInputStream();
byte[] b2 = new byte[(int)hc.getLength()];
dis.read(b2);
String html = new String(b2,"gb2312");
System.out.println(html);
new toGetList(html);
}catch(IOException e){
e.printStackTrace();
}
}
}这是我的这段代码 哪个地方不对给指点下 小弟 拜谢了

把拼接后的sql语句 在后台输出下 
看看到底是什么样子的sql

Answer 5

还是中文乱码的问题。从客户端传入后台的应该是iso8859-1
