Connection Reset in info log and didn’t get any response. What may be the cause?

ruberson.tria

This is the sample code in API that we use: (*The method is using for retrieve all world check iso country list.)

static String gatewayurl = "/v1/";

static String gatewayhost = "api-worldcheck.refinitiv.com";

public static void processingGetIsoCountryList() throws IOException {

_log.info("Entering the processingGetIsoCountryList method");

CloseableHttpClient httpclient = HttpClients.createDefault();

try {

Date now = new Date();

// format for date string Mon, 27 Mar 2017 15:19:36 GMT

DateFormat df = new SimpleDateFormat("EEE, dd MMM yyyy HH:mm:ss z");

df.setTimeZone(TimeZone.getTimeZone("GMT"));

String date = df.format(now);

String dataToSign = "(request-target): get " + gatewayurl

+ "reference/countries\n" + "host: " + gatewayhost + "\n"

+ "date: " + date;

String hmac = generateAuthHeader(dataToSign, apisecret);

String authorisation = "Signature keyId=\""

+ apikey

+ "\",algorithm=\"hmac-sha256\",headers=\"(request-target) host date\",signature=\""

+ hmac + "\"";

_log.info("dataToSign is......" + dataToSign);

_log.info("hmac is......" + hmac);

_log.info("authorisation is......" + authorisation);

HttpGet httpGet = new HttpGet(httpsUrl + "reference/countries");

httpGet.addHeader("Authorization", authorisation);

httpGet.addHeader("Cache-Control", "no-cache");

httpGet.addHeader("date", date);

CloseableHttpResponse response = httpclient.execute(httpGet);

try {

HttpEntity entity = response.getEntity();

_log.info("response.getStatusLine is.........."+ response.getStatusLine());

String json = EntityUtils.toString(response.getEntity());

_log.info("entity is......." + entity);

_log.info("json is......." + json);

ObjectMapper mapper = new ObjectMapper();

Object jsonObj = mapper.readValue(json, Object.class);

String indented = mapper.writerWithDefaultPrettyPrinter()

.writeValueAsString(jsonObj);

_log.info("indented is..........." + indented);

EntityUtils.consume(entity);

}

catch (Exception e) {

_log.info(e.getMessage());

} finally {

response.close();

}

} catch (Exception e) {

_log.info(e.getMessage());

} finally {

httpclient.close();

}

_log.info("Exiting the processingGetIsoCountryList method");

}

In the API.log, you will notice that after executing the code CloseableHttpResponse response = httpclient.execute(httpGet);

The connection was reset. It didn’t get any response.

This line of code was not called: _log.info("response.getStatusLine is.........."+ response.getStatusLine());

Here's the result in API.log

@ruberson.tria,

Can you please share the request and the response headers of the failed request? We would need both in order to investigate further on the cause of the error.

I didn't use request and response headers. I download the World-Check One API Java Request Code and World-Check One API Java v1.2 Collection Tool and incorporate it in our system. I use this to test the connectivity and authorization to the World-Check One API webserver as well as to retrieve information.

I want to check if my Java Code need some update to connect in the World-Check One API webserver.

@ruberson.tria,

Thanks for your response.

The code which you have downloaded is sample code, and may not work if you are using different development component. So I would advise you to please share the request and the response header, as Error 401, could be due to the different in the timestamps between request and response.
