Hi我正在开发一个集成支付系统，所以我需要理解在发布请求和读取响应时读取超时意味着什么。

根据我的理解，当我们在发布请求时获得读取时间时，这意味着我们的请求没有被发送到目的地，我们可以假设请求失败了。

我只想知道我的理解是正确的吗？

或者，任何人都可以解释在发布请求时获得读取超时的可能性。

这意味着请求没有发送到目的地，还是已经发送了？

public String postRequest(String request) throws Exception {
        logger.info("Calling postRequest method in " +this.getClass().getName());
        String responseData = null;
        HttpURLConnection httpConn = null;
        OutputStream out = null;
        InputStreamReader isr = null;


    bridgeUrl = new URL(StartupCache.getInstance().getConfigByKey(getUniqueKey(ConfigurationConstant.BRIDGE_URL))
            .getConfigValue());

    if (connectionTime == null) {
        connectionTime = StartupCache.getInstance().getConfigByKey(getUniqueKey(ConfigurationConstant.CONNECTION_TIME_OUT));
        if (connectionTime != null && connectionTime.getConfigValue().trim().length() > 0) {
            connectionTimeOutInMilliSec = Integer.valueOf(connectionTime.getConfigValue());
        }
    }

    try {
        if (bridgeUrl.getProtocol().equalsIgnoreCase("https")) {
            ignoreSslCertificateAuthentication();
            httpConn = (HttpsURLConnection) bridgeUrl.openConnection();
        } else {
            httpConn = (HttpURLConnection) bridgeUrl.openConnection();

        httpConn.setRequestMethod("POST");
        httpConn.setDoOutput(true);
        httpConn.setDoInput(true);
        httpConn.setConnectTimeout(connectionTimeOutInMilliSec);

        out = httpConn.getOutputStream();
        out.write(requestByte);
        logger.info("API Request sent at : " + sdf.format(new Date()));
        out.close();

            httpConn.disconnect();
        }
        throw new ApiRequestPostingException("Exception occured while posting : Reason : "+e.getMessage());
    }
    try {
        // Read the response and write it to standard out.
        isr = new InputStreamReader(httpConn.getInputStream());
        logger.info("API Response received at : " + sdf.format(new Date())+" Response Code : "+httpConn.getResponseCode() );
        BufferedReader br = new BufferedReader(isr);
        String temp;
        StringBuilder tmpResponseb = new StringBuilder();

        while ((temp = br.readLine()) != null) {
            tmpResponseb.append(temp);
        }
        responseData = tmpResponseb.toString();
        logger.info("Response Data : " +responseData+"\n");
        br.close();
        isr.close();
    } catch (java.net.MalformedURLException e) {
        logger.error("Error in postRequest(): Secure Service Required");
        e.printStackTrace();
    } catch (Exception e) {
        logger.error("Error in postRequest(): " + e.getMessage());
        e.printStackTrace();
    }finally {
        if (isr != null) {
            try {
                logger.info("Closing input stream connection....");
                isr.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
        if (httpConn != null) {
            logger.info("Disconnecting httpConn in reading finally block....");
            httpConn.disconnect();
        }
    }
    return responseData;
}

在发布请求时，我得到了连接超时异常。

根据我的理解，当我们在发布请求时获得读取时间时，这意味着我们的请求没有被发送到目的地，我们可以假设请求失败了。

这种假设是不正确的。读取超时和连接超时是不同的事情：

读取超时-请求已经发布并可能被处理，但是没有及时收到响应。因此，您不知道异常时请求发生了什么。

连接超时-请求失败。
