分享ssh或servlet获取request
手机向服务器传多张图片，网上找到能用的例子，网上的例子服务端用的是servlet，我自己服务端用的ssh，但是用ssh做服务端时request获取时有问题
android客户端（主要应该看服务端吧）
servlet服务端（这个是没有问题的）
TestDome
web.xml
ssh服务端（这里有问题）
UserAction
web.xml
struts.xml
不知道是不是ssh配置文件的问题，

/**
* 发送Post请求(图片)
* @param u 求情地址
* @param map 参数
*/
public String postRequest(String u,Map<String, String> map){
try{
//请求超时
httpClient.getParams().setParameter(CoreConnectionPNames.CONNECTION_TIMEOUT, 5000);
//读取超时
httpClient.getParams().setParameter(CoreConnectionPNames.SO_TIMEOUT, 5000);
//创建HttpPost对象
HttpPost post = new HttpPost(u);
//如果传递的参数个数比较多，可以对传递的参数进行封装
List<NameValuePair> params = new ArrayList<NameValuePair>();
for(String key:map.keySet()){
//封装请求的参数
params.add(new BasicNameValuePair(key, map.get(key)));
}
MultipartEntity entity = new MultipartEntity();
for(int i = 0; i<params.size();i++) {
//if (params.get(i).getName().equals(Integer.toString(i))) {
FileBody fileBody = new FileBody(new File(params.get(i).getValue()));
entity.addPart(params.get(i).getName(), fileBody);
//}
}
post.setEntity(entity);
//发送Post请求
HttpResponse httpResponse = httpClient.execute(post);
String result ="";
//服务器返回响应
if(httpResponse.getStatusLine().getStatusCode() == 200){
//获取响应的字符串
result = EntityUtils.toString(httpResponse.getEntity(),"UTF-8");
}else{
result = "network_error";
}
return result;

return "network_error";

struts配置里面还需要配置你的流
