我正在尝试使用apache httpClient调用应用程序，并且收到406响应，我已经设置了userAgent和accept标头，但是问题仍然存在。
但是使用java.net.HttpURLConnection的另一个代码可以调用具有相同有效负载的相同URL。
如果有人能向我指出apache客户端代码到底有什么问题，我将不胜感激，下面将发布这两个代码。
Apache客户端
public static JSONObject doPayment(String authorization, String signature, String nonce,String timestamp)
{
JSONObject resp = new JSONObject();
DateFormat dateFormatter = new SimpleDateFormat("yyyyMMddHHmmss");
try {
int CONNECTION_TIMEOUT = 60 * 1000; // timeout in millis
RequestConfig requestConfig = RequestConfig.custom()
.setConnectionRequestTimeout(CONNECTION_TIMEOUT)
.setConnectTimeout(CONNECTION_TIMEOUT)
.setSocketTimeout(CONNECTION_TIMEOUT)
.build();
CloseableHttpClient httpClient = getClient();
String payload ="{\"craccountno\":\"1006973695\",\"transactionType\":\"Internal\",\"amount\":\"11.00\",\"charges\":\"0\",\"draccountno\":\"1000203150\",\"transref\":\"MOJ54CVCCD467\",\"narration\":\"Transfer to ONWUASANYA CHIDILE OBINNA\",\"craccountname\":\"MOJEC PLC\",\"source\":\"MOJEC_MIDDLEWARE\",\"draccountname\":\"OBINNA CHIDILE ONWUASANYA\"}";
System.out.println("Time out for webservice is configured");
System.out.println("outgoing request: " + payload);
// HttpEntity httpEntity = new ByteArrayEntity(payload.getBytes("UTF-8"));
BasicHttpEntity entity = new BasicHttpEntity();
entity.setContent(new ByteArrayInputStream(payload.getBytes("UTF-8")));
entity.setContentLength(payload.getBytes("UTF-8").length);
String url = "http://localhost:8080/T24Gateway/services/qucoon/transaction/ft";
System.out.println("URL for Payment is " + url);
HttpPost httpPost = new HttpPost(url);
httpPost.setConfig(requestConfig);
httpPost.setHeader("nonce", nonce);
httpPost.setHeader("Timestamp", timestamp);
httpPost.setHeader("Authorization", authorization);
httpPost.setHeader("Signature", signature);
httpPost.setHeader("Content-Type","application/json; charset=utf-8");
httpPost.setHeader("Accept", "application/json");
String encodedData = URLEncoder.encode( payload.toString(), "UTF-8");
//httpPost.(Integer.toString(encodedData.length()) );
httpPost.setHeader("User-Agent", "Pigeon");
httpPost.setEntity(entity);
HttpResponse response = httpClient.execute(httpPost);
String rawResponse = EntityUtils.toString(response.getEntity());
System.out.println("Raw response :" + rawResponse);
resp = new JSONObject(rawResponse);
}
catch(ConnectTimeoutException ex)
{
System.out.println("Timeout connecting to T24 service" + ex.getMessage());
}
catch(SocketTimeoutException ex)
{
System.out.println("Timeout receiving response from t24 service" + ex.getMessage());
}
catch (Exception e) {
e.printStackTrace();
}
return resp;
}
用于上述目的的客户配置
public static CloseableHttpClient getClient() throws Exception
{
CloseableHttpClient client = HttpClients.custom().setUserAgent( "Pigeon")
.setSSLSocketFactory(new SSLConnectionSocketFactory(
SSLContexts.createSystemDefault(),
new String[]{"TLSv1.2"},
new String[] {"TLS_RSA_WITH_AES_256_CBC_SHA256"},
SSLConnectionSocketFactory.getDefaultHostnameVerifier()))
.build();
return client;
}
