调用方法,传过去接口地址和参数(json对象或者map,在方法里转成json字符串)
JSONObject.toJSONString(map)
JSONObj.toString()
public static String getResult(String url,Map<String, String> params){
String returnValue = null;
HttpClient httpclient = new DefaultHttpClient();
httpclient.getParams().setParameter(CoreConnectionPNames.SO_TIMEOUT, 15000);
try {
HttpPost httppost = new HttpPost(url);
httppost.addHeader("Content-type","application/json; charset=utf-8");
httppost.setHeader("Accept", "application/json");
StringEntity entity = new StringEntity(JSONObject.toJSONString(params),Charset.forName("UTF-8"));
httppost.setEntity(entity);
HttpResponse resp = httpclient.execute(httppost);
if(resp.getStatusLine().getStatusCode() == 200) {
HttpEntity he = resp.getEntity();
String respContent = EntityUtils.toString(he,"UTF-8");
returnValue = respContent;
}
}
catch (SocketTimeoutException e) {
e.printStackTrace();
returnValue = "timeout";
}catch (Exception e) {
e.printStackTrace();
}finally {
// 关闭连接,释放资源
httpclient.getConnectionManager().shutdown();
}
return returnValue;
}
