一、request.getReader()和DocumentHelper.parseText()

import java.io.BufferedReader;
import javax.servlet.http.HttpServletRequest;
import org.dom4j.Document;
import org.dom4j.DocumentHelper;
import org.dom4j.Element;

private String parseRequestBody(HttpServletRequest request,String uuid,Logger log) throws Exception{
		BufferedReader br = request.getReader();
		String str=""; 
		String wholeStr = "";
		while((str = br.readLine()) != null){
			wholeStr += str;
		}
		log.info(uuid+"獲取到的request的body："+wholeStr);
		wholeStr = wholeStr.replaceAll(" ", "");
		Document document = DocumentHelper.parseText(wholeStr);
		Element root = document.getRootElement();
		String msgType = root.elementText("MsgType");
	}
 

二、request.getInputStream()和new SAXReader().read(輸入流);

import java.io.InputStream;
import java.io.Writer;
import javax.servlet.http.HttpServletRequest;
 
import org.dom4j.Document;
import org.dom4j.Element;
import org.dom4j.io.SAXReader;

public static Map<String, String> parseXml(HttpServletRequest request) throws Exception {
		// 將解析結果儲存在HashMap中
		Map<String, String> map = new HashMap<String, String>();
 
		// 從request中取得輸入流
		InputStream inputStream = request.getInputStream();
		// 讀取輸入流
		SAXReader reader = new SAXReader();
		Document document = reader.read(inputStream);
		// 得到xml根元素
		Element root = document.getRootElement();
		// 得到根元素的所有子節點
		
		@SuppressWarnings("unchecked")
		List<Element> elementList = root.elements();
 
		// 遍歷所有子節點
		for (Element e : elementList)
			map.put(e.getName(), e.getText());
 
		// 釋放資源
		inputStream.close();
		inputStream = null;
 
		return map;

}
 

三、二進位制讀取

public void binaryReader(HttpServletRequest request) {

    int len = request.getContentLength();
    ServletInputStream iii = request.getInputStream();
    byte[] buffer = new byte[len];
    iii.read(buffer, 0, len);
}
