httpClient服务端编写
以前用过HttpClient,给你说几个关键的地方吧:
1. 首先,发送的时候
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);
当然了,还可能有其他的一些形式,这里不过多的说明了,有API可以参考
private void parseRequest(HttpServletRequest request) throws Exception { boolean isMultipart = ServletFileUpload.isMultipartContent(request); if (isMultipart) { DiskFileItemFactory factory = new DiskFileItemFactory(); ServletFileUpload upload = new ServletFileUpload(factory); List items = upload.parseRequest(request); for (int i = 0; i < items.size(); i++) { FileItem item = (FileItem) items.get(i); if (!item.isFormField()) { //文件数据 } else { //普通表单数据 } } } else { Enumeration en = request.getParameterNames(); while (en.hasMoreElements()) { String paramName = (String) en.nextElement(); String paramValue = request.getParameter(paramName); } } }
