ByteArrayInputStream isc = new ByteArrayInputStream(xml.getBytes());//HttpEntity e = new InputStreamEntity(isc,ContentType.APPLICATION_XML);//post.setEntity(e);post.setEntity(new ByteArrayEntity(xml.getBytes())); |
xml是退款参数
InputStreamEntity 和 ByteArrayEntity都试过,一直返回
<xml><return_code><![CDATA[FAIL]]></return_code><return_msg><![CDATA[缺少参数]]></return_msg></xml> |
下面的代码基本是抄官网的demo（官网也不提示的完整一些是怎么提交xml，还有到处查资料）
* 执行请求 * @param xml 封装的参数 * @return 返回执行结果 */ private String doSslRequest(String xml) { // Trust own CA and all self-signed certs CloseableHttpClient httpclient = null; CloseableHttpResponse response = null; HttpEntity httpEntity = null; InputStreamReader entityStream = null; try { char[] mchid = AppConfig.getPaymchId().toCharArray(); KeyStore keyStore = getKeyStore(mchid); SSLContext sslcontext = SSLContexts.custom() .loadKeyMaterial(keyStore, mchid).build(); // Allow TLSv1 protocol only String[] tlsv1 = { "TLSv1" }; HostnameVerifier hostname = SSLConnectionSocketFactory.getDefaultHostnameVerifier(); SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory( sslcontext, tlsv1, null, hostname); httpclient = HttpClients.custom().setSSLSocketFactory(sslsf).build(); // HttpGet httpget = new HttpGet(D_URL_PAYREFUND); HttpPost post = new HttpPost(D_URL_PAYREFUND); ByteArrayInputStream isc = new ByteArrayInputStream(xml.getBytes()); //HttpEntity e = new InputStreamEntity(isc,ContentType.APPLICATION_XML); //post.setEntity(e); post.setEntity(new ByteArrayEntity(xml.getBytes())); response = httpclient.execute(post); httpEntity = response.getEntity(); log.debug("----------------------------------------"); log.debug(response.getStatusLine().toString()); if (httpEntity == null) { log.error("请求返回null"); return null; } log.debug("Response content length: " + httpEntity.getContentLength()); entityStream = new InputStreamReader(httpEntity.getContent(), Tools.encode.UTF8); char[] buf = new char[1024 * 16]; StringBuilder responseText = new StringBuilder(); int l; while ((l = entityStream.read(buf)) != -1) { responseText.append(buf, 0, l); } return responseText.toString(); } catch (Exception e) { log.error("微信支付ssl请求出错", e); throw new YMException("微信支付ssl请求出错:" + e.getMessage()); } finally { Tools.io.close(entityStream); close(httpEntity); Tools.io.close(response); Tools.io.close(httpclient); } } |
补充下XML的内容
<xml><appid><![CDATA[是正确的]]></appid><mch_id><![CDATA[是正确的]]></mch_id><nonce_str><![CDATA[201808101626400971]]></nonce_str><notify_url><![CDATA[https://www.netsupper.top/print/wx/payment/paynotify/refund]]></notify_url><out_refund_no><![CDATA[188AG2640X660000]]></out_refund_no><out_trade_no><![CDATA[188AF2642X660000]]></out_trade_no><refund_desc><![CDATA[退还赏金]]></refund_desc><refund_fee><![CDATA[1]]></refund_fee><sign_type><![CDATA[MD5]]></sign_type><total_fee><![CDATA[1]]></total_fee><transaction_id><![CDATA[]]></transaction_id></xml>
