如何在java中获取sharepoint项目的listItemId值

Question

我正在尝试使用java中sharepoint的ListsSoap web服务来获取当前位于sharepoint上的docx文件的附件。并试图将docx文件下载到我的本地磁盘。然而，现在我在以下代码中尝试从sharepoint获取XML时出错

我明白了 “Microsoft”类型的例外。SharePoint。SoapServer。引发了“SoapServerException”

SharepointReference sharepointReference = new SharepointReference();
ListsSoap listsSoap = sharepointReference.getListAuth("sharepointId","sharepointPassword");
GetAttachmentCollectionResponse.GetAttachmentCollectionResult x = listsSoap.getAttachmentCollection("listName", "28");

参数中的“28”指的是listitems的ows_ID列的值。我不确定这是否是getAttachmentCollection的第二个参数获取的列表项的listItemId

有人知道是因为身份验证问题还是因为listItemId无效而抛出错误吗

如何设置和验证的逻辑在SharepointReference类及其getListAuth方法中被屏蔽。由于不知道逻辑，我们无法确定原因。下面的逻辑是通过web服务访问SharePoint列表内容的典型方法。你可以试试这个这还没有准备好编译，因为我从我的解决方案中借用了一些片段（由于IP原因，我无法共享这些片段）

public void GetAttachments {
    String endPoint = "http://YourSiteUrlIncludingTheSubweb"+"/_vti_bin/Lists.asmx";

    //set proper authentication
    java.net.CookieManager cm = new java.net.CookieManager();
    java.net.CookieHandler.setDefault(cm);
    Authenticator.setDefault(new SPAuthenticator());

    //Connect to list
    Lists service = new Lists(new URL(endPoint+"?wsdl"),
            new QName("http://schemas.microsoft.com/sharepoint/soap/", "Lists"));
    ListsSoap soap = service.getListsSoap();
    BindingProvider bp = (BindingProvider) soap;
    bp.getRequestContext().put(BindingProvider.USERNAME_PROPERTY, "domain\username");
    bp.getRequestContext().put(BindingProvider.PASSWORD_PROPERTY, "password");
    bp.getRequestContext().put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, endPoint);

    //get attachments
    port.getAttachmentCollection(...)
    .
    .
    .
}

这是我们的垃圾邮件认证者。java类

public class SPAuthenticator extends Authenticator {

    public PasswordAuthentication getPasswordAuthentication() {
        return new PasswordAuthentication("domain\username","password".toCharArray());
    }
}

希望这有帮助
