EWS Java API - 连接错误

EWS Java API - Connection error

我想我已经用尽了这个选项。我在互联网上搜索了几天,但没有找到有类似问题的人。

我正在使用 EWS Java API 1.2.1 连接到 Exchange 服务器并打开我的收件箱文件夹以查找电子邮件。这是我的代码:

import java.net.URI;

import microsoft.exchange.webservices.data.*;

public class Connection {

    /**
     * @param args
     */
    public static void main(String[] args) throws Exception {

        ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010_SP2);

        ExchangeCredentials credentials = new WebCredentials("myUser", "myPass");

        service.setCredentials(credentials);

        service.setUrl(new URI("https://example.com/ews/exchange.asmx"));

        service.setTraceEnabled(true);

        Folder inbox = Folder.bind(service, WellKnownFolderName.Inbox);
        System.out.println("messages: " + inbox.getTotalCount());
    }
}

当我 运行 它时,出现以下错误:

Exception in thread "main" microsoft.exchange.webservices.data.ServiceLocalException: https://example.com/ews/exchange.asmx : Connection error 
at microsoft.exchange.webservices.data.ExchangeServiceBase.prepareHttpWebRequestForUrl(Unknown Source)

at microsoft.exchange.webservices.data.Folder.bind(Unknown Source)
at microsoft.exchange.webservices.data.Folder.bind(Unknown Source)
at Connection.main(Connection.java:22)

我认为它可能会阻止我的连接尝试,但当我使用 JWebServices API.

时,它确实适用于上述 URL 和用户凭据

顺便说一句,我也可以从我的浏览器访问 WSDL。

有什么线索吗?

提前致谢!

这可能是因为引用了错误的 JAR Class。

您使用的是什么 JAR。以及这里使用的是哪个版本的 EWS API??

我在使用 EWS API 1.2 时遇到了同样的问题,在参考了以下 JAR 后,它得到了解决。

EWSJavaAPI_1.2original.jar, EWSJavaAPIWithJars_1.2.1.jar, httpclient-4.2.5.jar, httpcore-4.2.4.jar, jcifs-1.3.17.jar, commons-codec-1.7.jar, commons-logging-1.1.1.jar

EWSJavaAPI_1.2original.jar - 这是微软相关的 Classes EWSJavaAPIWithJars_1.2.1.jar - 这个有它的连接相关 Classes.

尝试添加这些 JAR。
