昨天工作正常的 url 的 java.io.FileNotFoundException

Question

我昨天能够从 get 请求中获取数据，但是今天如果我调用相同的 api 我得到了

java.io.FileNotFoundException: https://api.quikr.com/jobs/v1/zwayam/application?companyName=test&jobId=123

引起：java.io.FileNotFoundException：https://api.quikr.com/jobs/v1/zwayam/application?companyName=test&jobId=123 在 sun.net.www.protocol.http.HttpURLConnection.getInputStream0（未知来源） 在 sun.net.www.protocol.http.HttpURLConnection.getInputStream（未知来源） 在 java.net.HttpURLConnection.getResponseCode（未知来源） 在 sun.net.www.protocol.https.HttpsURLConnectionImpl.getResponseCode（未知来源） 在 com.zwayam.controller.QuikrDataPoint.getJobApplicationForQuikrJobs(QuikrDataPoint.java:159) ... 1 更多

我无法直接在浏览器中访问此 api，因为需要设置一些应用程序标头 这是编码问题还是api问题？

    String urlstr = "https://api.quikr.com/jobs/v1/zwayam/application?";

        List<NameValuePair> params = new LinkedList<NameValuePair>();

        params.add(new BasicNameValuePair("companyName", "test"));
        params.add(new BasicNameValuePair("jobId", "123"));
        String paramString = URLEncodedUtils.format(params, "utf-8");

        url = new URL(urlstr + paramString);

        connection = (HttpURLConnection) url.openConnection();
        connection.setRequestMethod("GET");
        connection.setDoOutput(true);
        connection.setRequestProperty("Accept", "application/json");
        System.setProperty("http.agent", "");
        Calendar cal = Calendar.getInstance();
        SimpleDateFormat format = new SimpleDateFormat("YYYY-MM-dd");
        String todaysDate = format.format(cal.getTime());
        String emailId = "roshan@zwayam.com";
        String data = appId + emailId + todaysDate;
        SecretKeySpec signingKey = new SecretKeySpec(tokenKey.getBytes(), "HmacSHA1");
        Mac mac = Mac.getInstance("HmacSHA1");
        mac.init(signingKey);
        String signature = toHexString(mac.doFinal(data.getBytes()));
        connection.setRequestProperty("Content-Type", "application/JSON");
        connection.setRequestProperty("X-Quikr-App-Id", "890");
        connection.setRequestProperty("X-Quikr-Token-Id", tokenId.toString());
        connection.setRequestProperty("X-Quikr-Signature-v2", signature);
        connection.setRequestProperty("User-Agent", "Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.4; en-US; rv:1.9.2.2) Gecko/20100316 Firefox/3.6.2");
        int responseCode = connection.getResponseCode();

这是调用api的部分，我得到的响应码是404

问题出在 api 上，他们修复了它，现在可以正常工作了 :)
