对了，服务器的JSONObject需要用到包：http://download.csdn.net/download/alan_tw/10273273

客户端的接收:
if (conn.getResponseCode() == 200) {
// 获取响应的输入流对象
InputStream is = conn.getInputStream();
// 创建字节输出流对象
ByteArrayOutputStream message = new ByteArrayOutputStream();
// 定义读取的长度
int len = 0;
// 定义缓冲区
byte buffer[] = new byte[1024];
// 按照缓冲区的大小，循环读取
while ((len = is.read(buffer)) != -1) {
// 根据读取的长度写入到os对象中
message.write(buffer, 0, len);
}
String x=new String(message.toByteArray());
JSONArray jsonArray = new JSONArray(x);
for (int i=0;i<1;i++){ //我只有一个数组
JSONObject jsonObject = jsonArray.getJSONObject(i);
age1=jsonObject.getString("age");
name1=jsonObject.getString("name");
name.setText(name1+"");
age.setText(age1+"");
if (jsonObject.getString("sex").equals("男")){
Message msg = handler1.obtainMessage();
msg.what = 1;
handler1.sendMessage(msg);
}else{
Message msg = handler1.obtainMessage();
msg.what = 0;
handler1.sendMessage(msg);
}
}
}
客户端发送数据：
JSONObject ClientKey = new JSONObject();
ClientKey.put("name", name.getText().toString());
ClientKey.put("age", age.getText().toString());
ClientKey.put("sex", sex2);
ClientKey.put("phone", phone.getText().toString());
/*封装Person数组*/
JSONObject params = new JSONObject();
params.put("User", ClientKey);
/*把JSON数据转换成String类型使用输出流向服务器写*/
String content = String.valueOf(params);
Log.e("content:",content);
HttpURLConnection conn = (HttpURLConnection) new URL("http://10.0.2.2:8888/AndroidLogin/information/Information").openConnection();
//设置请求方式,请求超时信息
conn.setRequestMethod("POST");
conn.setRequestProperty("User-Agent", "Fiddler");
conn.setRequestProperty("Content-Type", "application/json");
conn.setRequestProperty("Charset", "UTF-8");
conn.setReadTimeout(5000);
conn.setConnectTimeout(5000);
conn.setDoOutput(true);
conn.setDoInput(true);
conn.setUseCaches(false);
OutputStream out = conn.getOutputStream();
out.write(content.getBytes());
out.flush();
服务器接收json：
StringBuilder sb = new StringBuilder();
String s = null;
InputStreamReader isr = new InputStreamReader(new BufferedInputStream(request.getInputStream()),"UTF-8");
BufferedReader br = new BufferedReader(isr);
while((s=br.readLine())!=null){
sb.append(s);
}
JSONObject object = JSONObject.fromObject(sb.toString()).getJSONObject("User");
user.setName(object.getString("name"));
user.setAge(object.getInt("age"));
user.setSex(object.getString("sex"));
user.setPhoneNumber(object.getString("phone"));
服务器发送json：
StringBuffer sb = new StringBuffer();
sb.append('[');
sb.append('{').append("\"name\":")
.append("\"" + items.getName() + "\"").append(",");
sb.append("\"age\":").append("\"" + items.getAge() + "\"").append(",");
sb.append("\"sex\":").append("\"" + items.getSex() + "\"");
sb.append('}');
sb.append(']');
out.write(new String(sb));
最近刚好在做，我的是没有问题，希望可以帮到你。
