bloomberg无法启动会话

Question

我使用bloomberg API来获取市场数据，这是API SDK提供的示例

package blpapi;

import com.bloomberglp.blpapi.CorrelationID;
import com.bloomberglp.blpapi.Element;
import com.bloomberglp.blpapi.Event;
import com.bloomberglp.blpapi.Message;
import com.bloomberglp.blpapi.MessageIterator;
import com.bloomberglp.blpapi.Name;
import com.bloomberglp.blpapi.Request;
import com.bloomberglp.blpapi.Service;
import com.bloomberglp.blpapi.Session;
import com.bloomberglp.blpapi.SessionOptions;

public class SimpleRefDataExample {
    private static final Name SECURITY_DATA = new Name("securityData");
    private static final Name SECURITY = new Name("security");
    private static final Name FIELD_DATA = new Name("fieldData");
    private static final Name FIELD_EXCEPTIONS = new Name("fieldExceptions");
    private static final Name FIELD_ID = new Name("fieldId");
    private static final Name ERROR_INFO = new Name("errorInfo");
    private CorrelationID d_cid;

    public static void main(String[] args) throws Exception {
        SimpleRefDataExample example = new SimpleRefDataExample();
        example.run(args);
        System.out.println("Press ENTER to quit");
        System.in.read();
    }

    private void run(String[] args) throws Exception {
        String serverHost = "localhost";
        int serverPort = 35230;

        SessionOptions sessionOptions = new SessionOptions();
        sessionOptions.setServerHost(serverHost);
        sessionOptions.setServerPort(serverPort);

        Session session = new Session(sessionOptions);

        System.out.println("Connecting to " + serverHost + ":" + serverPort);
        if (!session.start()) {
            System.err.println("Failed to start session.");
            return;
        }
        System.out.println("Connected successfully.");

        if (!session.openService("//blp/refdata")) {
            System.err.println("Failed to open //blp/refdata");
            return;
        }

        Service refDataService = session.getService("//blp/refdata");
        Request request = refDataService.createRequest("ReferenceDataRequest");

        // append securities to request
        Element securities = request.getElement("securities");
        securities.appendValue("IBM US Equity");
        securities.appendValue("/cusip/912828GM6@BGN");

        // append fields to request
        Element fields = request.getElement("fields");
        fields.appendValue("PX_LAST");
        fields.appendValue("DS002");

        System.out.println("Sending Request: " + request);
        d_cid = session.sendRequest(request, null);

        while (true) {
            Event event = session.nextEvent();
            MessageIterator msgIter = event.messageIterator();
            while (msgIter.hasNext()) {
                Message msg = msgIter.next();
                if (msg.correlationID() == d_cid) {
                    processMessage(msg);
                }
            }
            if (event.eventType() == Event.EventType.RESPONSE) {
                break;
            }
        }
    }

    private void processMessage(Message msg) throws Exception {
        Element securityDataArray = msg.getElement(SECURITY_DATA);
        int numSecurities = securityDataArray.numValues();
        for (int i = 0; i < numSecurities; ++i) {
            Element securityData = securityDataArray.getValueAsElement(i);
            System.out.println(securityData.getElementAsString(SECURITY));
            Element fieldData = securityData.getElement(FIELD_DATA);
            for (int j = 0; j < fieldData.numElements(); ++j) {
                Element field = fieldData.getElement(j);
                if (field.isNull()) {
                    System.out.println(field.name() + " is NULL.");
                } else {
                    System.out.println(field);
                }
            }
            Element fieldExceptionArray =
                securityData.getElement(FIELD_EXCEPTIONS);
            for (int k = 0; k < fieldExceptionArray.numValues(); ++k) {
                Element fieldException =
                    fieldExceptionArray.getValueAsElement(k);
                System.out.println(
                        fieldException.getElement(ERROR_INFO).getElementAsString("category")
                        + ": " + fieldException.getElementAsString(FIELD_ID));
            }
            System.out.println("\n");
        }
    }
}

收到此错误：

run:
Connecting to localhost:35230
Failed to start session.
Press ENTER to quit

本地主机通过xampp在我的系统上运行，我尝试使用默认端口：8080，并且没有端口也没有工作，然后我启动了玻璃鱼服务器，它也工作http://localhost:35230但仍然得到这个错误需要更多的配置？

Answer 1

本地bbcomm进程的默认端口通常为8194.您需要运行bbcomm.exe进程并通过Bloomberg终端连接到Bloomberg。

Answer 2

如果您使用的是Desktop API，Bloomberg API会“不”让您连接到本地主机以外的任何其他计算机。这是设计的。

如上所述，DesktopAPI的默认端口是8194.检查BBCOMM.CFG文件以查看您是否使用端口8194。

还可以直接从命令提示符运行BBCOMM文件，以查看是否出现错误。

如果您使用的是ServerAPI让我知道...
