我想做一个用java提交post请求的客户端应用。
浏览器网址：http://www.pkuschool.edu.cn/Qingjia/QingjiaG.aspx
post提交地址：http://www.pkuschool.edu.cn/Qingjia/Data/AjaxService.aspx?method=SaveQingjiaG
网站是用miniui做的，根据表单自动生成json数据，提交到服务器，返回一个json字符串。
我无法查看服务器端文件代码，但根据现有调试成果，服务器端先检测是否是json数据，每个jsonObject是否齐全，然后再检测每个json的值是否匹配。我模拟提交的json是齐全的，但服务端返回{"returnMessage":"信息提交异常，详细信息：输入字符串的格式不正确。","isSend":null}，我认为是中文乱码问题。
我提交的数据是抓包后用UTF-8解码的数据，即：[{\"Nianji\":\"高中2015届\",\"Banji\":\"元培书院\",\"Xuehao\":\"1525998\",\"Xingming\":\"姓名\",\"JianhurenShouji\":\"11111111111\",\"QingjiaLeixing\":\"病假\",\"KaishiShijian\":\"2014-05-24T00:00:00\",\"KaishiJie\":\"第1节\",\"JieshuShijian\":\"2014-05-24T00:00:00\",\"JieshuJie\":\"第1节\",\"QingjiaYuanyin\":\"原因\",\"key\":\"\",\"pagesize\":5}]
客户端代码：
import org.apache.http.HttpResponse;
import org.apache.http.NameValuePair;
import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.HttpClient;
import org.apache.http.client.entity.UrlEncodedFormEntity;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.message.BasicNameValuePair;
import org.apache.http.params.BasicHttpParams;
import org.apache.http.params.HttpParams;
import org.apache.http.protocol.HTTP;
import org.apache.http.util.EntityUtils;
public class LeaveSetTest2 {
public static void main(String[] args) {
String data1 = "[{\"Nianji\":\"高中2015届\",\"Banji\":\"元培书院\",\"Xuehao\":\"1525998\",\"Xingming\":\"姓名\",\"JianhurenShouji\":\"11111111111\",\"QingjiaLeixing\":\"病假\",\"KaishiShijian\":\"2014-05-24T00:00:00\",\"KaishiJie\":\"第1节\",\"JieshuShijian\":\"2014-05-24T00:00:00\",\"JieshuJie\":\"第1节\",\"QingjiaYuanyin\":\"原因\",\"key\":\"\",\"pagesize\":5}]";
List<NameValuePair> list = new ArrayList<NameValuePair>();
HttpResponse response = null;
try {
data1 = new String(data1.getBytes("GBK"), "UTF-8");
list.add(new BasicNameValuePair("data", data1));
HttpParams params = new BasicHttpParams();
HttpClient client = new DefaultHttpClient(params);
String uri = "http://www.pkuschool.edu.cn/Qingjia/Data/AjaxService.aspx?method=SaveQingjiaG";
HttpPost post = new HttpPost(uri);
post.setEntity(new UrlEncodedFormEntity(list));
response = client.execute(post);
System.out.println(EntityUtils.toString((response.getEntity())));
} catch (Exception e1) {
e1.printStackTrace();
}
}
}
求大神能帮我调试一下。。。我把各种编码都试了。。。才疏学浅，实在无力解决了。。。
此网站没有登录什么的，完全就是一个独立的post，无cookie,session。。。
求帮忙！！
