httpClient服务端编写

HttpClient client = new HttpClient();
PostMethod method = new PostMethod(URL);//具体method里面还可以设置一下编码，header之类的
//1. 第一种方式，基于Content-Type=‘multipart/form-data’形式的表单
Part[] parts = ...;//FilePart和StringPart都可以放进去
method.setRequestEntity(new MultipartRequestEntity(parts, method.getParams()));
//2. 第二种方式，普通表单
NameValuePair[] pairs = ...;//纯参数了，键值对
method.addParameters(pairs);

client.executeMethod(method);

private void parseRequest(HttpServletRequest request) throws Exception {

for (int i = 0; i < items.size(); i++) {
