android中使用HttpClient的简单例子

public boolean uploadHttpClient(String path, Map<String, String> params) throws IOException{
//1.参数放进一个list集合当中，每个参数是一个NameValuePair对象
List<NameValuePair> paramPair = new ArrayList<NameValuePair>();
if(params != null && !params.isEmpty()){
for(Map.Entry<String, String> entry : params.entrySet()){
paramPair.add(new BasicNameValuePair(entry.getKey(), entry.getValue()));
}
}
//2.创建请求实体对象，参数集合作为构造参数
UrlEncodedFormEntity entity = new UrlEncodedFormEntity(paramPair, "utf-8");
//3.创建post请求，并把实体对象放进去
HttpPost post = new HttpPost(path);
post.setEntity(entity);
//4.创建请求客户端，并执行请求，获得相应
DefaultHttpClient client = new DefaultHttpClient();
HttpResponse  res = client.execute(post);

if(res.getStatusLine().getStatusCode() == 200){
return true;
}

return false;
}
