从JAVA到Sharepoint 2013 REST API的BASIC身份验证

Question

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

倾向于使用BASIC身份验证：

在网络上有许多使用其余api的示例，但似乎没有一个可以处理身份验证。也许我在这里错过了一些非常简单的事情。

这可以通过POSTMAN手动进行：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。

我试过实现此：
使用HttpClientBuilder基本身份验证

<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

Answer 1

感谢@fateddy能够解决问题：切记将UsernamePasswordCredentials（“ username”，“
password”））;换成NTCredentials（，，，）;

使用此Maven依赖项：

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

对SharePoint的身份验证有效：

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();
    }
}
}

然后您得到：HTTP / 1.1 200 OK
