HTTP 使用POST发送请求 request接受不到数据

Question

javaweb 使用POST请求另一个服务器，服务器request获取不到数据 全部为null

Answer 1

request获取的参数时form-encoding形式的参数，你传标注json格式的数据过去是解析不出来的，你可以按我贴的代码这样包装一下试试看。

这是httpClient调用类
public static String httpPost(List params, String url) throws Exception {
String body = "";
HttpPost httpPost = null;
String requestParams = "";
try {
DefaultHttpclient httpClient = new DefaultHttpclient();
httpPost = new HttpPost();
// 设置参数
httpPost.setURI(new URI(url));
httpPost.setEntity(new UrlEncodedFormEntity(params, "UTF-8"));
requestParams = EntityUtils.toString(new UrlEncodedFormEntity(params));
// 发送请求
HttpResponse httpresponse = httpClient.execute(httpPost);
// 获取返回数据
HttpEntity entity = httpresponse.getEntity();
body = EntityUtils.toString(entity, "UTF-8");

        if (entity != null) {
            EntityUtils.consume(entity);
        }
    } catch (ConnectException ce) {
        ce.printStackTrace();
        logger.error("ConnectException " + url + "  连接异常," + requestParams);
    } catch (Exception e) {
        e.printStackTrace();
        logger.error("Exception:  " + url + " 异常," + requestParams);
    } finally {
        try {
            if (httpPost != null) {
                httpPost.releaseConnection();
            }
        } catch (Exception e) {
            logger.error("Exception: release  http connection error!");
        }
    }
    return body;
}

 这是参数包装

List params = new ArrayList();
params.add(new BasicNameValuePair("storeid", “123”)));
params.add(new BasicNameValuePair("load",“2323”)));

 请试一下吧，若解决问题请搭赏几个c币 嘿嘿
