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维基页面，但无法找到记录的方法。
我一直在看这里的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
专门研究文件和维基的API，似乎没有关于维基页面附件的内容。虽然我主要想要上传附件，但我甚至看不到用于检索附件的文档化API，尽管用户界面有一个指向Feed的链接（在每个维基页面上）。
是否有任何（可能是未记录的）API将文件附加到维基页面？

以下是一些示例代码，用于说明如何以受支持的方式执行此操作。
首先，您需要两个网址。
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Nonce
/**
* 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;
}
现在你有了诸如...之类的随机数... b1911872-36f1-4767-956d-214759886406
然后使用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和XML
