servlet读取xml格式的post数据

 

服务器端代码：

 

 

rundata.getModuleInfo().setLayoutTemplate(null);

        HttpServletRequest request = rundata.getRequest();
        HttpServletResponse response = rundata.getResponse();

        PrintWriter printWriter = null;
        ServletInputStream sis = null;

        String xmlData = null;

        try {
            printWriter = response.getWriter();
            // 取HTTP请求流
            sis = request.getInputStream();
            // 取HTTP请求流长度
            int size = request.getContentLength();
            // 用于缓存每次读取的数据
            byte[] buffer = new byte[size];
            // 用于存放结果的数组
            byte[] xmldataByte = new byte[size];
            int count = 0;
            int rbyte = 0;
            // 循环读取
            while (count < size) {
                // 每次实际读取长度存于rbyte中
                rbyte = sis.read(buffer);
                for(int i=0;i<rbyte;i++) {
                    xmldataByte[count + i] = buffer[i];
                }
                count += rbyte;
            }

            xmlData = new String(xmldataByte, "UTF-8");

 

 

 

 

客户端代码：

 

 

HttpClient httpClient = new HttpClient();
String xmlData = getInput();
int xmlDataLength = xmlData.getBytes("UTF-8").length;
PostMethod method = new PostMethod(url);
method.setRequestBody(xmlData);
method.setRequestHeader("Content-type", "text/xml; charset=UTF-8");
if (xmlDataLength < Integer.MAX_VALUE) {
    method.setRequestContentLength(xmlDataLength);
} else {
    method.setRequestContentLength(EntityEnclosingMethod.CONTENT_LENGTH_CHUNKED);
}

try {
    int statusCode = httpClient.executeMethod(method);
    System.out.println("返回码： " + statusCode);
    if(statusCode != HttpStatus.SC_OK) {
        return;
    }
    System.out.println("输出:");
    System.out.println(method.getResponseBodyAsString());
} catch (IOException e) {
    e.printStackTrace();
} finally {
    method.releaseConnection();
}
