ibm-connections - IBM Connections API - 如何将文件附加到 wiki 页面？

Question

在 IBM Connections 用户界面中，可以将文件直接附加到 wiki 页面。
我想以编程方式将文件附加到 wiki 页面，但找不到记录的方法。

我一直在查看 Connections 4.5 API 文档:
http://www-10.lotus.com/ldd/appdevwiki.nsf/xpDocViewer.xsp?lookupName=IBM+Connections+4.5+API+Documentation#action=openDocument&content=catcontent&ct=prodDoc

专门查看文件和 Wiki 的 API，似乎没有关于 wiki 页面附件的内容。虽然我主要是想上传附件，但我什至看不到用于检索附件的文档化 API，尽管用户界面有一个链接到一个提要(在每个 wiki 页面上)这样做。

是否有任何(可能未记录的)API 将文件附加到 wiki 页面？

Answer 1

以下是一些示例代码，用于展示如何以受支持的方式执行此操作。

首先，您需要两个 URL。

private static String apiUrlWikiNonce = "https://sdkdev.swg.usma.ibm.com:444/wikis/basic/api/nonce";
private static String apiUrlWikiAttachment = "https://sdkdev.swg.usma.ibm.com:444/wikis/form/api/wiki/{WIKI_LABEL_OR_WIKI_UUID}/page/{PAGE_LABEL_OR_PAGE_UUID}/feed";

获取随机数

   /**
     * gets the nonce value only valid return type is text, anything else throws
     * an error
     * 
     * @param httpClient
     * @param user
     * @param password
     * @return
     */
    public static String getNonce(CloseableHttpClient httpClient, String user,
            String password) {
        String result = "";
        HttpGet httpGet = new HttpGet(apiUrlWikiNonce);

        String combo = user + ":" + password;
        String hash = org.apache.commons.codec.binary.Base64
                .encodeBase64String(combo.getBytes());
        System.out.println(user + " is logging in with " + hash);
        String auth = "Basic " + hash;
        httpGet.setHeader("Authorization", auth.replace("=", ""));

        HttpClientContext context = HttpClientContext.create();

        CloseableHttpResponse response = null;
        try {

            response = httpClient.execute(httpGet, context);

            System.out.println(response.getStatusLine());
            HttpEntity entity = response.getEntity();

            InputStream is = entity.getContent();
            StringWriter writer = new StringWriter();

            IOUtils.copy(is, writer);
            String responseString = writer.toString();
            // System.out.println(responseString);

            result = responseString;

            EntityUtils.consume(entity);
        } catch (ClientProtocolException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            try {
                response.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }

        return result;
    }

现在你有随机数，比如... b1911872-36f1-4767-956d-214759886406

然后用 X-Update-Nonce 上传文件

/**
     * uploads a file to a given wiki page.
     * 
     * @param httpClient
     * @param user
     * @param password
     * @param wikiLabel
     * @param wikiPage
     * @param file
     * @param nonce
     * @return uuid <empty or uuid of file>
     */
    public static String uploadFileToWiki(CloseableHttpClient httpClient, String user,
            String password, String wikiLabel, String wikiPage, File file, String nonce){
        String uuid = "";

        String apiUrl = apiUrlWikiAttachment.replace("{WIKI_LABEL_OR_WIKI_UUID}", wikiLabel);
        apiUrl = apiUrl.replace("{PAGE_LABEL_OR_PAGE_UUID}", wikiPage);

        //Mandatory Parameter
        apiUrl += "?category=attachment";


        System.out.println("API Url : " + apiUrl);

        HttpPost post = new HttpPost(apiUrl);
        post.addHeader("User-Agent", "Mozilla/5.0 (Macintosh; Intel Mac OS X 10.9; rv:32.0) Gecko/20100101 Firefox/32.0");
        post.addHeader("Content-Type", "image/png");

        String combo = user + ":" + password;
        String hash = org.apache.commons.codec.binary.Base64
                .encodeBase64String(combo.getBytes());
        System.out.println(user + " is logging in with " + hash);
        String auth = "Basic " + hash;
        post.setHeader("Authorization", auth.replace("=", ""));

        HttpClientContext context = HttpClientContext.create();

        CloseableHttpResponse response = null;
        try {
            EntityBuilder builder = EntityBuilder.create();
            builder.setFile(file);
            HttpEntity postentity = builder.build();

            post.setHeader("Slug","NominalWorkItem-v1.png");
            post.setHeader("title","Test Title");
            post.setHeader("label","Test Test");

            post.setEntity(postentity);

            response = httpClient.execute(post, context);

            System.out.println(response.getStatusLine());
            HttpEntity entity = response.getEntity();

            InputStream is = entity.getContent();
            StringWriter writer = new StringWriter();

            IOUtils.copy(is, writer);
            String responseString = writer.toString();
            System.out.println(responseString);

            uuid = responseString;

            EntityUtils.consume(entity);
        } catch (ClientProtocolException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            try {
                response.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }


        return uuid;
    }

文件已更新，您在创建时获得响应代码 201，以及 XML
