从外部应用程序登录到 Content Navigator

Question

我正在尝试从我的 Java 应用程序（FileNet P8 中的事件操作处理程序）访问 Content Navigator 上的 PluginService。该应用程序使用 JAXRS 登录服务从 Content Navigator 服务器接收 security_token。但是，如果我尝试调用 PluginService，我会收到一个响应，提示我的登录已过期。

我能够获取安全令牌，如代码块中所述：

URL logonUrl = new URL("http://icn-host:9081/jaxrs/logon"
    + "?userid=user"
    + "&password=password"
    + "&desktop=admin"
    + "&contextPath=%2Fnavigator");
HttpURLConnection logonConnection = (HttpURLConnection)logonUrl.openConnection();
logonConnection.setRequestMethod("POST");
logonConnection.setRequestProperty("Content-Type",
    "application/x-www-form-urlencoded");
logonConnection.setDoOutput(true);
InputStream logonResponse = logonConnection.getInputStream();
String responseText = IOUtils.toString(logonResponse, "UTF-8")
    .replaceFirst("^\{}&&", "");
JSONObject responseJson = JSONObject.parse(responseText);
return (String)responseJson.get("security_token");

但是当我尝试发出另一个请求时，我收到错误响应：

URL requestUrl = new URL("http://icn-host:9081/plugin.do"
    + "?plugin=myPlugin&action=myPluginService&myRequestProps=foobar");
HttpURLConnection requestConnection =
    (HttpURLConnection)requestUrl.openConnection();
requestConnection.setRequestMethod("GET");
String securityToken = getSecurityToken(); // calls above code
requestConnection.setRequestProperty("security_token", securityToken);
equestConnection.setDoOutput(true);
InputStream responseStream = requestConnection.getInputStream();
String responseText = IOUtils.toString(responseStream, "UTF-8")
    .replaceFirst("^\{}&&", "");
log.info("response was: " + responseText);

我总是收到以下回复：

{
  "messagesEncoded":true,
  "errors": [
    {
      "adminResponse":null,
      "moreInformation":null,
      "explanation":"Your session expired because of inactivity.",
      "number":"1003",
      "userResponse":"Log in again.",
      "text":"Your session expired."
    }
  ]
}

我也试过设置 cookie，但没有成功。

java.net.CookieManager cookieManager = new java.net.CookieManager();
Map<String, List<String>> headerFields = logonConnection.getHeaderFields();
List<String> cookiesHeader = headerFields.get("Set-Cookie");
if (cookiesHeader != null) {
  for (String cookie : cookiesHeader) {
    cookieManager.getCookieStore().add(null, HttpCookie.parse(cookie).get(0));
  }
}

// ...

StringBuilder cookieHeader = new StringBuilder();
List<HttpCookie> cookies = cookieManager.getCookieStore().getCookies();

for (int i = 0; i < cookies.size(); i++) {
  if (i > 0) {
    cookieHeader.append(";");
  }

  HttpCookie cookie = cookies.get(i);
  log.info("Cookie " + i + ": " + cookie.toString());
  cookieHeader.append(cookie.toString());
}

requestConnection.setRequestProperty("Cookie", cookieHeader.toString());

我尝试在 Content Navigator window 中使用 XMLHttpRequest 复制请求，它按预期工作：

var xhr = new XMLHttpRequest();
xhr.open("GET", "plugin.do" +
    "?plugin=myPlugin" +
    "&action=myPluginService" +
    "&myRequestProps=foobar");
xhr.setRequestHeader("security_token", ecm.model.Request._security_token);
xhr.send();

Answer 1

几个月前，我遇到了一个客户的类似挑战，我不得不自动执行安装插件和应用配置的过程 CI 目的。

我发现获取桌面是登录后第一个 api 调用的关键，会话变为 'valid'。

所以首先 jaxrs/logon，然后 jaxrs/getDesktop，然后调用您的服务。

一点旁注：如果您计划以后使用容器管理身份验证，则过程会有所不同。 jaxrs/logon 将不起作用，而 jaxrs/getDesktop 将提供 security_token.

但要注意一点：拥有一个共享库，您可以将事件操作中的两者都用作 ICN 服务，这不是更好的解决方案吗？

Answer 2

使用共享库（参见 Ivo 的回答）绝对是最好的方法，调用 jaxrs/getDesktop 对我不起作用。相反，我只是使用 Maven Assembly Plugin 来包含更新版本的 org.apache.httpcomponents 依赖项并使用 HttpClient 调用请求。

我的最终代码如下所示：

CloseableHttpClient httpClient = HttpClients.custom()
  .setDefaultCookieStore(cookieStore)
  .setDefaultRequestConfig(requestConfig)
  .build();
HttpUriRequest logonRequest = RequestBuilder.post()
  .setUri("http://icn-host:9081/navigator/jarxrs/logon")
  .addParameter("desktop", "admin")
  .addParameter("contextPath", "/navigator")
  .addParameter("userid", "icnadmin")
  .addParameter("password", "password")
  .build();
CloseableHttpResponse logonResponse = httpClient.execute(logonRequest);
HttpEntity responseEntity = logonResponse.getEntity();
String responseText = EntityUtils.toString(responseEntity)
  .replaceFirst("^\{}&&", "");
JSONObject responseJson = JSONObject.parse(responseText);
String securityToken = (String) responseJson.get("security_token");
HttpUriRequest request = RequestBuilder.get()
  .setUri("http://icn-host:9081/navigator/plugin.do")
  .addParameter("plugin", "myPlugin")
  .addParameter("action", "myPluginService")
  .addParameter("myRequestProps", "foobar")
  .addHeader("security_token", securityToken)
  .build();
HttpClientContext context = HttpClientContext.create();
CookieStore cookieStore = new BasicCookieStore();
context.setCookieStore(cookieStore);
CloseableHttpResponse response = httpClient.execute(request, context);
