Question

我尝试使用Apache的Xml-Rpc库在Java中进行方法调用时出现了一个奇怪的错误。这是设置：

XmlRpcClientConfigImpl config = new XmlRpcClientConfigImpl();
    URL url = null;
    try {
        url = new URL(Config.getInstance().getProperty("foo.host"));
    } catch (MalformedURLException e) {
        e.printStackTrace();
    }
    config.setServerURL(url);

    client = new XmlRpcClient();
    client.setConfig(config);

    //Generate Token for all admin calls
    try {
        token = (String) client.execute("confluence2.login",
                new Object[]{ADMIN_USER, ADMIN_PASS});
    } catch (XmlRpcException e) {
        log.error("There was a problem getting the rpc token", e);
    }

多个其他方法使用的辅助方法适用于除有问题之外的所有其他方法：

private <T> T executeWikiMethod(String method, Object[] params) throws WikiException {
    try {
        Object[] args = new Object[params.length + 1];
        args[0] = token;
        System.arraycopy(params, 0, args, 1, args.length - 1);

        long startTime = System.currentTimeMillis();
        T t = (T) client.execute(method, args);
        log.debug(String.format("Wiki RPC call to method: %s and params: %s. Request completed in %dms", method, Arrays.toString(args), System.currentTimeMillis() - startTime));

        return t;
    } catch (XmlRpcException e) {
        throw new WikiException(e.getMessage());
    } catch (Exception e) {
        log.error(e.getMessage());
        throw new WikiException("An unexpected error occurred.");
    }
}

最后，这里的方法打破了错误消息＆＃34;无法解析服务器响应：意外的非空白字符数据＆＃34;：

public Object getWikiUpdates(String wikiSpaceKey) throws WikiException {
    Object result;

    result = executeWikiMethod("recentupdate.getRecentUpdate", new Object[]{wikiSpaceKey, "10"});

    return result;
}

应该有来自服务器的xml响应，使用RPC库将其解析为JSON对象。 getWikiUpdates（）方法应该返回一个JSON块，表示维基页面的几种不同类型的更新（例如新注释等），其格式目前是未知的，因为调用返回错误而没有xml响应或任何JSON。我正在使用Object，希望能够捕获从方法调用返回的内容，并能够从那里格式化结果。这一切都在Play中完成！框架。如果我需要进一步澄清，请告诉我。谢谢。

编辑 - 服务器响应是＆＃34;意外的非空白字符数据＆＃34;，没有别的

Answer 1

两件事 - 方法参数应该以confluence2开头，例如confluence2.getRecentUpdate。但这导致第二个问题......

“recentupdate.getRecentUpdate”不是有效的方法。我没有在这里看到任何类似的内容：https://developer.atlassian.com/confdev/confluence-rest-api/confluence-xml-rpc-and-soap-apis/remote-confluence-methods

查看你的代码，我认为你想要的可能是搜索方法之一，如矢量搜索（String token，String query，Map parameters，int maxResults），你可以在其中指定空间和限制等。

您可以使用方法名称“confluence2.search”

来调用它
