如何使用Java将文档上载到SharePoint？

我正在用Java创建一些大文件（DB导出），我需要将它们放在SharePoint服务器上的某个位置。现在，我正在用IE来做这件事，但我也想自动化这一步

我在网上搜索了一下，找到了一些使用SOAP的提示，但我还没有真正了解这一切的实质。有人能提供一些示例代码或食谱给我我需要做什么吗

请注意：SharePoint服务器要求NT域身份验证。我甚至无法使用Firefox登录：(

• 如何将IE中可怕的URL转换为WebDAV路径
• 在我用我的代码破坏生产系统之前，是否有一个WebDAV“explorer”可以使用？我从中尝试了“DAV explorer 0.91”，但无法连接（可能是因为NT域身份验证）

---

我可以想出不同的选择：

• 将文档库映射到文件驱动器，并像文件系统中的任何其他文件一样保存该文件
• 使用HTTP WebDAV协议

…对于NTLM身份验证部分：

此外，您还可以使用SharePoint SOAP web服务。每个SharePoint网站通过路径

http:///_vti_bin/

在您的情况下，您可能需要（

http:///_vti_bin/Lists.asmx

）。您可以从

http:///_vti_bin/Lists.asmx?WSDL

。WSS 3.0 SDK提供了有关如何使用web服务的详细信息（您可能需要使用

UpdateListItems

和

AddAttachment

方法）

综上所述，Sacha的第一个选项（将文档库映射到驱动器）可能是假设您可以绕过NTLM问题的最简单的方法

如果您使用的是Windows，则只需导航到文档库的UNC路径即可。例如，如果文档库的浏览器URL为：

http:///Foo/BarDocs/Forms/AllItems.aspx

您只需在Windows资源管理器地址栏中键入相应的UNC路径：

\\\Foo\BarDocs

---

然后将文件拖放到此位置。如果愿意，可以使用Windows资源管理器或SUBST.EXE命令行实用程序将此位置映射到驱动器号。

好的……经过几个小时的工作并仔细阅读“文档”MicroSoft提供了所有提示，并且所有提示都随机分布在网络上。我已经设法编写了一些示例代码来浏览SharePoint服务器的内容：

下一站：上传内容。

另一个解决方案是使用HTTP PUT方法将文件直接发送到Sharepoint

为此，您可以使用Apache HTTP客户端：

<dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpclient</artifactId>
    <version>4.2.3</version>
</dependency>

使用身份验证执行HTTP PUT的主代码：

    try {

        HttpParams params = new BasicHttpParams();
        HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
        DefaultHttpClient httpclient = new DefaultHttpClient(params);

        //Register JCIF NTLMv2 to manage ntlm auth.
        httpclient.getAuthSchemes().register("ntlm", new AuthSchemeFactory() {
            @Override
            public AuthScheme newInstance(HttpParams hp) {
                return new NTLMScheme(new JCIFSEngine());
            }
        });

        //Provide login/password
        httpclient.getCredentialsProvider().setCredentials(
                AuthScope.ANY,
                new NTCredentials([LOGIN], [PASSWORD], "", [DOMAIN]));
        //Create HTTP PUT Request       
        HttpPut request = new HttpPut("http://[server]/[site]/[folder]/[fileName]");
        request.setEntity(new FileEntity([File]));            

        return httpclient.execute(request);

    } catch (IOException ex) {
      //...
    }

---

我想我的方法可能会对你有所帮助

最初，我创建了sharepoint帐户，并按照此链接（）中的过程获取REST API所需的凭据。获得凭据后，我只需要以下依赖项和代码：

<dependency>
        <groupId>org.apache.httpcomponents</groupId>
        <artifactId>httpclient</artifactId>
        <version>4.5</version>
</dependency>

org.apache.httpcomponents
httpclient
4.5

因为我使用了OAUTH2身份验证，所以获取访问令牌的代码有助于其他CRUD操作

/* OAuth2 authentication to get access token */
public String getSharePointAccessToken() throws ClientProtocolException, IOException
{
    /* Initializing variables */
    String grant_type = RcConstants.GRANT_TYPE;
    String client_id = RcConstants.CLIENT_ID;
    String client_secret = RcConstants.CLIENT_SECRET;
    String resource = RcConstants.RESOURCE;
    String url = RcConstants.OAUTH_URL + RcConstants.URL_PARAMETER + "/tokens/OAuth/2";

    /*
     * NOTE: RcConstants.OAUTH_URL =
     * https://accounts.accesscontrol.windows.net/ RcConstants.URL_PARAMETER

     * postman/) Figure 6.
     */

    /* Building URL */
    HttpClient client = HttpClientBuilder.create().build();
    HttpPost post = new HttpPost(url);
    post.setHeader("Content-Type", "application/x-www-form-urlencoded");

    /* Adding URL Parameters */
    List<NameValuePair> urlParameters = new ArrayList<NameValuePair>();
    urlParameters.add(new BasicNameValuePair("grant_type", grant_type));
    urlParameters.add(new BasicNameValuePair("client_id", client_id));
    urlParameters.add(new BasicNameValuePair("client_secret", client_secret));
    urlParameters.add(new BasicNameValuePair("resource", resource));
    post.setEntity(new UrlEncodedFormEntity(urlParameters));

    /* Executing the post request */
    HttpResponse response = client.execute(post);
    logger.debug("Response Code : " + response.getStatusLine().getStatusCode());

    String json_string = EntityUtils.toString(response.getEntity());
    JSONObject temp1 = new JSONObject(json_string);  
    if (temp1 != null)
    {
        /* Returning access token */
        return temp1.get("access_token").toString();
    }
    return RcConstants.OAUTH_FAIL_MESSAGE;
}
