我需要把对象的数组(每个对象有2个场)作为参数在HTTP请求的URL。 我怎样才能做到这一点,这个环节应该怎么样子?
Answer 1:
你可以用你的结构的XML即对象的数组,每个都具有两个字段,然后将其转换成字符串,作为一个例子,
String input = String.format("<Request><Data><Id>%s</Id></Data>
</Request>",studentIdSelected);
然后调用此方法输入和URL作为参数张贴您的数据,
public static String retriver(String Url, String input) {
String responseString = null;
StringEntity stringEntity;
HttpPost postRequest = new HttpPost(Url);
try {
Log.e("string is", input + "\n" + Url);
stringEntity = new StringEntity(input, "UTF-8");
stringEntity.setContentType("application/atom+xml");
postRequest.setEntity(stringEntity);
Log.v("Post", "Posted");
HttpClient httpclient = new DefaultHttpClient();
HttpResponse response = httpclient.execute(postRequest);
HttpEntity getResponseEntity = response.getEntity();
responseString = EntityUtils.toString(getResponseEntity);
} catch (Exception e) {
// TODO: handle exception
postRequest.abort();
Log.w("HttpPostRetreiver", "Error for URL " + Url, e);
}
return responseString;
}
或者您可以使用JSON为好。
Answer 2:
最好的解决办法是JSON或XML格式发送HTTP POST请求。
