本人新手，最近在java 的xml格式的http報文，希望哪位大俠給指點指點。

現給出報文格式，跪求類似傳送和解析http報文的詳細例子。

傳送的報文格式：

POST ***********************************************

Accept: *****************************************

Referer: *****************************************

Accept-Language: *****************************************

Content-Type:*****************************************

//資料部分

 RESULT:xxxxx

 //引數

Parameter-Length: \r\n\r\n

<ParameterObjecOBJECTNAME=*************>

<ParaName>ParameterKey</ParaName>

<Value>0</Value>

<ParaName>*************</ParaName>

<Value>*************</Value>

<ParaName>*************</ParaName>

<Value>*************</Value>

<ParaName>*************</ParaName>

<Value>*************</Value>

</ParameterObjec>

返回報文格式：

HTTP/1.1 200 OK

Content-Type:*************

Transfer-Encoding:*************

Connection:*************

RESULT:xxxxx

Parameter-Length: 0 \r\n\r\n 

程式碼如下：

URL url = new URL("XXXXX");
HttpURLConnection conn = (HttpURLConnection) url.openConnection();


conn.setConnectTimeout(Utils.TIMEOUT);
// conn.setReadTimeout(6000);
conn.setDoOutput(true);
conn.setRequestMethod("POST");
conn.setRequestProperty("POST",
XXXXX");


// 增加報頭
conn.setRequestProperty(
"Accept",
"XXXXX");
conn.setRequestProperty("Referer",
"XXXXX");
conn.setRequestProperty("Accept-Language", "XXXXX");
.....

//資料部分
StringBuffer parameterObject = new StringBuffer();
parameterObject
.append("<ParameterObject  OBJECTNAME='XXXXX' >");
parameterObject.append("\r\n");
parameterObject.append("<ParaName>XXXXX</ParaName>");
parameterObject.append("\r\n");
parameterObject.append("<Value>XXXXX</Value>");
parameterObject.append("\r\n");

parameterObject.append("</ParameterObject>");
parameterObject.append("\r\n");


// 開啟流，寫入xml資料
StringBuffer data = new StringBuffer();
data.append("RESULT:xxx");
data.append("\r\n");
data.append("Parameter-Length:");
data.append(parameterObject.toString().length());
data.append("\r\n");
data.append("\r\n");
data.append(parameterObject);


// 打出傳送的報文資訊
Utils.LogMessage("send device info xml :\r\n" + data.toString());
OutputStream outputStream = conn.getOutputStream();
outputStream.write(data.toString().getBytes());
outputStream.flush();
outputStream.close();
if (conn.getResponseCode() != HttpURLConnection.HTTP_OK) {
return;
}
InputStream input = conn.getInputStream();
BufferedReader reader = new BufferedReader(new InputStreamReader(
input, Utils.CHARSET));
String line = null;
StringBuffer httpRawData = new StringBuffer();
while ((line = reader.readLine()) != null) {
httpRawData.append(line).append("\r\n");
}


if (reader != null) {
reader.close();
}
if (conn != null) {
conn.disconnect();
}


// 打出接受的報文資訊
String httpRawDatas = httpRawData.toString();
Utils.LogMessage("accept device info xml :\r\n" + httpRawDatas);


Map<String,String> InformationMap=new HashMap<String, String>();
InformationMap.put("result", findOprCode(httpRawDatas,""))
InformationMap.put(Utils.DEVICE_NUMBER, Common.getAttributeValue(httpRawDatas,
"XXX1"));



} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

// 根據http返回的資料，解析出結果
public static String findOprCode(String data, String codeName) {
int codeStartIndex = data.indexOf(codeName);
int codeEndIndex = data.indexOf("\\r\n", codeStartIndex);
String resultCode = data.substring(codeStartIndex, codeEndIndex).trim();
return resultCode;
}


public static String getAttributeValue(String httpData, String attribute) {
int attributeIndex = httpData.indexOf(attribute);
int formerValueIndex = httpData.indexOf("<Value>", attributeIndex);
int laterValueIndex = httpData.indexOf("</Value>", formerValueIndex);
return httpData.substring(formerValueIndex, laterValueIndex);
}
