怎么给http post添加参数

Posted 2023-03-17

我要向php服务器上传文件，但是不知道怎么添加一下像下面的参数userid="12312";sessionid="234" in it.who can help me！ thanks！

给http post传参，参考以下二个实例：
//serverURL url地址
HttpPost httpPost = new HttpPost(serverURL);
//param 为参数
StringEntity entity = new StringEntity(param);
entity.setContentType("application/x-www-form-urlencoded");
httpPost.setEntity(entity);
HttpResponse httpResponse = httpClient.execute(httpPost);
还可以用map作为参数
List<NameValuePair> formparams = new ArrayList<NameValuePair>();
if(param!=null)
Set set = param.keySet();
Iterator iterator = set.iterator();
while (iterator.hasNext())
Object key = iterator.next();
Object value = param.get(key);
formparams.add(new BasicNameValuePair(key.toString(), value.toString()));

参考技术A 用HttpKit.post方法，可以传参，不过是要以map的形式才行。例如：
String resp = HttpKit.post(URL, paramStr, headerMap); 参考技术B List nameValuePairs = new ArrayList(2); nameValuePairs.add(new BasicNameValuePair("userid", "12312")); nameValuePairs.add(new BasicNameValuePair("sessionid", "234")); httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
