我正在使用这个实验性 api https://github.com/mtorak/java-lync-client 连接到我们的 lync 2013 服务器。

但是它根本不起作用。我可以将包部署到 jboss 7.1.1 调用 web 服务，但答案是否定的。日志显示如下：

我查看了代码，我知道它失败的地方，这才是真正的开始。

在 authenticate() 方法中有以下调用。

LyncHttpOperationWrapper httpOpWrapper1 = doFirstRequest();
            if (httpOpWrapper1 != null) 
                JsonNode node;
                try 
                    node = mapper.readTree(httpOpWrapper1.getResponseBody());

似乎 doFirstRequest() 正在执行 get，但服务器拒绝它。

我尝试在 Firefox 中访问相同的 url，我得到了答案，我没有被拒绝。

<resource rel="root" href="https://abs.example.com/Autodiscover/AutodiscoverService.svc/root?originalDomain=example.com">
<link rel="user" href="https://abs.example.com/Autodiscover/AutodiscoverService.svc/root/oauth/user?originalDomain=example.com"/>
<link rel="xframe" href="https://abs.example.com/Autodiscover/XFrame/XFrame.html"/>

客户端设置如下：

private static final String LYNC_DISCOVERY_URL_KEY = "lyncDiscoveryUrl"; private static final String LYNC_DISCOVERY_URL_VALUE = "@987654323@";

private static final String RESPONSE1_LINKS_SELF_HREF = "_links-self-href";
private static final String RESPONSE1_LINKS_USER_HREF = "_links-user-href";
private static final String RESPONSE1_LINKS_XFRAME_HREF = "_links-xframe-href";
private static final String RESPONSE_HEADER_WWW_AUTHENTICATE = "WWW-Authenticate";
private static final String RESPONSE_HEADER_VALUE_MSRTCOAUTH = "MsRtcOAuth";
private static final String RESPONSE_HEADER_VALUE_BEARER = "Bearer";
private static final String LYNC_EXT_POOL_HOST = "lyncextpool.example.com";
private static final String LYNC_EXT_POOL_URL = "https://lyncextpool.example.com";

private static final String X_MS_ORIGIN_HEADER_VALUE = "http://192.168.0.10";
private static final String X_MS_ORIGIN_HEADER_KEY = "X-Ms-Origin";

private static final String PROTOCOL_HTTPS = "https";
private static final String SSL_CONTEXT = "SSL";
private static final int SSL_PORT = 443;

如何从 linux，用 java 连接到 Lync 2013？

非常感谢您提前提供的帮助。

【参考方案1】：

我终于明白了通讯是怎么回事。

问题在于实际上服务器不接受标头，因为它认为请求是外部的。

所以对于全部 5 个请求，删除 HOST 和 X_MS_ORIGIN_HEADER 允许协商，我可以访问网页。

    httpPost.setHeader(HttpHeaders.ACCEPT, "application/json");
    httpPost.setHeader(HttpHeaders.CONTENT_TYPE, "application/json");
    httpPost.setHeader(HttpHeaders.AUTHORIZATION, authHeaderValue);

    httpPost.setHeader(HttpHeaders.ACCEPT_ENCODING, "gzip,deflate");
    httpPost.setHeader(HttpHeaders.ACCEPT_LANGUAGE, "en-US");
    httpPost.setHeader(HttpHeaders.CACHE_CONTROL, "no-cache");
    httpPost.setHeader(HttpHeaders.CONNECTION, "keep-alive");
    //httpPost.setHeader(HttpHeaders.HOST, LYNC_EXT_POOL_HOST); <= Was the bad guy
    //httpPost.setHeader(X_MS_ORIGIN_HEADER_KEY, X_MS_ORIGIN_HEADER_VALUE);  <= Was the bad guy

希望这可能对其他人有所帮助。网络服务真的很有用，谢谢分享。

【讨论】：

X-Ms-Origin 标头与需要使用跨域框架进行通信的 javascript 实现相关。在任何非 JavaScript 实现中，可以删除此标头。如果您要查看失败的响应，它很可能提供了一个错误代码，表明 X_MS_ORIGIN_HEADER_VALUE 不在跨域授权列表中。
