我正在使用Java创建一些大文件(数据库导出),我需要将它们放在我们的SharePoint服务器上。现在,我正在用IE做这个,但我也希望自动化这一步。
我搜索了网页,我发现了一些使用SOAP的提示,但我还没有真正看到所有这些。有人可以提供我需要做的一些示例代码或配方吗?
请注意:SharePoint服务器要求进行NT域身份验证。我甚至无法使用Firefox登录:(

除了Sacha's suggestions之外,您还可以使用SharePoint SOAP Web服务。每个SharePoint站点都通过路径http://<Site>/_vti_bin/
公开了一堆Web服务。
在您的情况下,您可能需要Lists web service(http://<Site>/_vti_bin/Lists.asmx
)。您可以从http://<Site>/_vti_bin/Lists.asmx?WSDL
获取WSDL。 WSS 3.0 SDK详细介绍了如何使用Web服务(您可能希望使用UpdateListItems
和AddAttachment
方法)。
所有这一切,Sacha的第一个选择(将文档库映射到驱动器)可能是最容易解决NTLM问题的方法。
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://<Site>/Foo/BarDocs/Forms/AllItems.aspx
您只需在Windows资源管理器地址栏中输入相应的UNC路径:
\\<Site>\Foo\BarDocs
然后将文件拖放到此位置。如果您愿意,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咬住自己通过“文档”MicroSoft提供并随机传播到网上的所有提示,我设法编写了一些示例代码来浏览SharePoint服务器的内容:Navigating SharePoint Folders With Axis2。

另一种解决方案是使用 HTTP PUT方法将文件直接发送到Sharepoint。
为此,您可以使用 Apache HTTP Client :
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>
<version>4.2.3</version>
</dependency>
要允许NTLMv2身份验证,您需要 JCIF 库。
<dependency>
<groupId>jcifs</groupId>
<artifactId>jcifs</artifactId>
<version>1.3.17</version>
</dependency>
首先,我们需要编写一个包装器,以允许Apache HTTP Client使用JCIF进行NTLMv2支持:
public final class JCIFSEngine implements NTLMEngine {
private static final int TYPE_1_FLAGS =
NtlmFlags.NTLMSSP_NEGOTIATE_56
| NtlmFlags.NTLMSSP_NEGOTIATE_128
| NtlmFlags.NTLMSSP_NEGOTIATE_NTLM2
| NtlmFlags.NTLMSSP_NEGOTIATE_ALWAYS_SIGN
| NtlmFlags.NTLMSSP_REQUEST_TARGET;
@Override
public String generateType1Msg(final String domain, final String workstation)
throws NTLMEngineException {
final Type1Message type1Message = new Type1Message(TYPE_1_FLAGS, domain, workstation);
return Base64.encode(type1Message.toByteArray());
}
@Override
public String generateType3Msg(final String username, final String password,
final String domain, final String workstation, final String challenge)
throws NTLMEngineException {
Type2Message type2Message;
try {
type2Message = new Type2Message(Base64.decode(challenge));
} catch (final IOException exception) {
throw new NTLMEngineException("Invalid NTLM type 2 message", exception);
}
final int type2Flags = type2Message.getFlags();
final int type3Flags = type2Flags
& (0xffffffff ^ (NtlmFlags.NTLMSSP_TARGET_TYPE_DOMAIN | NtlmFlags.NTLMSSP_TARGET_TYPE_SERVER));
final Type3Message type3Message = new Type3Message(type2Message, password, domain,
username, workstation, type3Flags);
return Base64.encode(type3Message.toByteArray());
}
}
使用身份验证执行HTTP PUT的主要代码:
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) {
//...
}

我使用集成的Windows标识设法启动并使用此代码将文件下载到sharepoint,这可能会有所帮助。
public class HttpClient {
HttpClient() { }
public static void download(final String source, final File resultingFile) {
CloseableHttpClient client = WinHttpClients.createSystem();
HttpGet httpRequest = new HttpGet(source);
CloseableHttpResponse httpResponse = null;
try {
httpResponse = client.execute(httpRequest);
HttpEntity entity = httpResponse.getEntity();
if(httpResponse.getStatusLine() != null && httpResponse.getStatusLine().getStatusCode() != HttpStatus.SC_OK) {
LOGGER.warn(httpResponse.getStatusLine());
}else {
LOGGER.debug(httpResponse.getStatusLine());
FileUtils.touch(resultingFile);
InputStream is = entity.getContent();
File outFile = new File(resultingFile.getAbsolutePath());
FileOutputStream fos = new FileOutputStream(outFile);
int inByte;
while ((inByte = is.read()) != -1) {
fos.write(inByte);
}
is.close();
fos.close();
client.close();
}
} catch (ClientProtocolException e) {
LOGGER.warn(e);
} catch (UnsupportedOperationException e) {
LOGGER.warn(e);
} catch (IOException e) {
LOGGER.warn(e);
}
}
public static void upload(final File source, final String destination) {
CloseableHttpClient httpclient = WinHttpClients.createSystem();
HttpPut httpRequest = new HttpPut(destination);
httpRequest.setEntity(new FileEntity(new File(source.getPath())));
CloseableHttpResponse httpResponse = null;
try {
httpResponse = httpclient.execute(httpRequest);
EntityUtils.consume(httpResponse.getEntity());
if (httpResponse.getStatusLine() != null && httpResponse.getStatusLine().getStatusCode() == HttpStatus.SC_CREATED) {
LOGGER.debug(httpResponse.getStatusLine());
LOGGER.info("Upload of " + source.getName() + " via HTTP-Client succeeded.");
} else if (httpResponse.getStatusLine() != null && httpResponse.getStatusLine().getStatusCode() == HttpStatus.SC_OK) {
LOGGER.debug(httpResponse.getStatusLine());
}else {
LOGGER.warn("Uploading " + source.getName() + " failed.");
LOGGER.warn(httpResponse.getStatusLine().getStatusCode() + ": " + httpResponse.getStatusLine().getReasonPhrase());
}
} catch (IOException e) {
LOGGER.warn(e);
LOGGER.warn(e.getMessage());
}
return;
}
}

我认为我的方法可能对你有帮助。
最初我创建了sharepoint帐户并按照此链接(http://www.ktskumar.com/2017/01/access-sharepoint-online-using-postman/)中的步骤获取REST API所需的凭据。一旦我获得了凭据,我需要的是以下依赖项和代码:
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>
<version>4.5</version>
</dependency>
由于我使用了OAUTH2身份验证,因此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
* = Bearer Realm from
* (http://www.ktskumar.com/2017/01/access-sharepoint-online-using-
* 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;
}
获得访问令牌后,我们可以使用以下方法上传:
public String putRecordInSharePoint(File file) throws ClientProtocolException, IOException
{
/* Token variable declaration */
String token = getSharePointAccessToken();
/* Null or fail check */
if (!token.equalsIgnoreCase(RcConstants.OAUTH_FAIL_MESSAGE))
{
/* Upload path and file name declaration */
String Url_parameter = "Add(url='" + file.getName() + "',overwrite=true)";
String url = RcConstants.UPLOAD_FOLDER_URL + Url_parameter;
/*
* NOTE: RcConstants.UPLOAD_FOLDER_URL =
* https://<your_domain>.sharepoint.com/_api/web/
* GetFolderByServerRelativeUrl('/Shared%20Documents/<FolderName>')/
* Files/
*/
/* Building URL */
HttpClient client = HttpClientBuilder.create().build();
HttpPost post = new HttpPost(url);
post.setHeader("Authorization", "Bearer " + token);
post.setHeader("accept", "application/json;odata=verbose");
/* Declaring File Entity */
post.setEntity(new FileEntity(file));
/* Executing the post request */
HttpResponse response = client.execute(post);
logger.debug("Response Code : " + response.getStatusLine().getStatusCode());
if (response.getStatusLine().getStatusCode() == HttpStatus.OK.value()|| response.getStatusLine().getStatusCode() == HttpStatus.ACCEPTED.value())
{
/* Returning Success Message */
return RcConstants.UPLOAD_SUCCESS_MESSAGE;
}
else
{
/* Returning Failure Message */
return RcConstants.UPLOAD_FAIL_MESSAGE;
}
}
return token;
}
