JAVA实现向SharePoint 2013 REST API进行BASIC身份验证

Java应用需要访问SharePoint 2013 REST API：https://msdn.microsoft.com/zh-cn/library/office/jj860569.aspx

想要使用基本身份验证：

网络上有很多使用REST API的示例，但好像没有涉及到身份验证。也许我在这里漏掉了什么非常简单的东西。

这个手动用POSTMAN是可行的： http://tech.bool.se/basic-rest-request-sharepoint-using-postman/ 但需要我在浏览器中输入用户名和密码。

我尝试着实现以下内容： HttpClientBuilder basic auth 使用

<dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpclient</artifactId>
    <version>4.4.1</version>
</dependency>

这导致->警告：NTLM身份验证错误：凭据无法用于NTLM身份验证：org.apache.http.auth.UsernamePasswordCredentials

看起来你需要NTLM身份验证 -> https://hc.apache.org/httpcomponents-client-ga/ntlm.html - fateddy

感谢 @fateddy，这就解决了问题：记得将 UsernamePasswordCredentials("username", "password") 替换为 NTCredentials(, , ,);

使用这个 maven 依赖：

<dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpclient</artifactId>
    <version>4.4.1</version>
</dependency>

SharePoint 的身份验证已经正常工作：

import org.apache.http.client.CredentialsProvider;
import org.apache.http.auth.AuthScope;
import org.apache.http.impl.client.BasicCredentialsProvider;
import org.apache.http.auth.NTCredentials;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.util.EntityUtils;

public class SharePointClientAuthentication {

public static void main(String[] args) throws Exception {
    CredentialsProvider credsProvider = new BasicCredentialsProvider();
    credsProvider.setCredentials(
            new AuthScope(AuthScope.ANY),
            new NTCredentials("username", "password", "https://hostname", "domain"));
    CloseableHttpClient httpclient = HttpClients.custom()
            .setDefaultCredentialsProvider(credsProvider)
            .build();
    try {
        HttpGet httpget = new HttpGet("http://hostname/_api/web/lists");

        System.out.println("Executing request " + httpget.getRequestLine());
        CloseableHttpResponse response = httpclient.execute(httpget);
        try {
            System.out.println("----------------------------------------");
            System.out.println(response.getStatusLine());
            EntityUtils.consume(response.getEntity());
        } finally {
            response.close();
        }
    } finally {
        httpclient.close();
    }
}
}

最终你会得到:

HTTP/1.1 200 OK
