我正在尝试访问我们公司的SharePoint 2013实例，该实例托管在ourinstance.sharepoint.com上，使用小型Java web应用程序。
我通过_layouts/15/AppRegNew注册了应用。Aspx:
- 我让SP生成客户端ID，客户端秘密，
- 到应用程序域I设置:ourdomain:8443
- 重定向URL I设置:
https://ourdomain:8443/our-redirect-processing
我用_layouts/15/appinv编辑了应用程序权限。我通过客户端ID查找它，并编辑了它的权限请求XML，以包含:
<AppPermissionRequests AllowAppOnlyPolicy="true">
<AppPermissionRequest Scope="http://insideidc.sharepoint.com/oursite/web" Right="FullControl"/>
</AppPermissionRequests>
https://ourdomain:8443/our-redirect-processing后面的处理器正在做这个:
JsonWebSignature jws = JsonWebSignature.parse(new JacksonFactory(), request.getParameter("SPAppToken"));
JsonParser jsonParser = new JacksonFactory().createJsonParser(jws.getPayload().get("appctx").toString());
AppCtx appCtx = jsonParser.parse(AppCtx.class, new CustomizeJsonParser());
String appctxsender=jws.getPayload().get("appctxsender").toString();
String[] splitApptxSender = appctxsender.split("@");
String sharepointServerHostName = new URL(request.getParameter("SPSiteUrl")).getHost();
String resource = splitApptxSender[0] + "/" + sharepointServerHostName + "@" + splitApptxSender[1];
AuthorizationCodeTokenRequest tokenRequest = new AuthorizationCodeTokenRequest(new NetHttpTransport(), new JacksonFactory(),
new GenericUrl(appCtx.getSecurityTokenServiceUri()), jws.getPayload().get("refreshtoken").toString());
tokenRequest.setRedirectUri(request.getRequestURL().toString());
String aud = (String) jws.getPayload().getAudience();
tokenRequest.setClientAuthentication(new ClientParametersAuthentication(aud, secrets.get(aud)));
tokenRequest.setGrantType("refresh_token");
tokenRequest.set("resource", resource);
tokenRequest.set("refresh_token", jws.getPayload().get("refreshtoken").toString());
TokenResponse response = tokenRequest.execute();
token = response.getAccessToken();
它使用com.google.api.client。Auth、HTTP和json类
我得到的令牌我在REST调用这个URL中使用:
https://ourinstance.sharepoint.com/oursite/_api/web/getFolderByServerRelativeUrl('/thefolderIwant')/Files
的标题:
Accept: application/json;odata=verbose
Authorization: Bearer theToken
响应要求我登录，而响应头设置了WWW-Authenticate: NTLM。
第一个问题:获得OAuth令牌的复杂过程是否应该以另一个凭据请求结束?第二个和主要问题:当SharePoint为我们托管时，我如何为我可以构建的NTLM认证器构建域用户名?
我在尝试访问微软的Project Online时也有类似的经历。我从AllThatJS中找到了一些有用的信息，这些信息为我指明了正确的方向。他建议使用Fiddler嗅探数据包。一旦我这样做了，我就看到了真正发生的事情。下面是我用来解决这个问题的一些Java代码，使用Apache的HttpClient、Apache的common-io和log4j来解决这个问题:
/**
This is for using Java to connect with Microsoft's Project Online
If you go into your Project Online, go to 'Server Settings' -> 'Manage Users', and look under the column 'User Logon Account'
If it looks like :
i:0#.w|domain\username
then you can just scroll down to where I call
httpclient.getCredentialsProvider().setCredentials(
new AuthScope(url.getHost(), url.getPort(), AuthScope.ANY_REALM, AuthScope.ANY_SCHEME),
new NTCredentials(
USERNAME,
PASSWORD,
url.getHost(),
DOMAIN));
However, if it looks more like :
i:0#.f|membership|username@yourcompany.com
then you'll need to use OAuth, which is what this file demonstrates.
