我按照 spring.io 网站上的说明进行操作:http://spring.io/guides/gs/accessing-twitter/
我没有连接上。 “findPrimaryConnection()”调用返回空值。我没有看到抛出任何异常。我确实在 .properties 文件中设置了 appId 和 appSecret。
Controller 代码如下:
@Controller
@RequestMapping("/")
public class HelloController {
private Twitter twitter;
private ConnectionRepository connectionRepository;
@Inject
public HelloController(Twitter twitter, ConnectionRepository connectionRepository) {
this.twitter = twitter;
this.connectionRepository = connectionRepository;
}
@RequestMapping(method=RequestMethod.GET)
public String helloTwitter(Model model) {
if (connectionRepository.findPrimaryConnection(Twitter.class) == null) {
System.out.println("******** no connection yet: " + connectionRepository.findPrimaryConnection(Twitter.class));
return "redirect:/connect/twitter";
}
System.out.println("******** connection found");
model.addAttribute(twitter.userOperations().getUserProfile());
CursoredList<TwitterProfile> friends = twitter.friendOperations().getFriends();
model.addAttribute("friends", friends);
return "hello";
}
}
这是 HTML 表单:
<form action="/connect/twitter" method="POST">
<div class="formInfo">
<p>You aren't connected to Twitter yet. Click the button to connect this application with your Twitter account.</p>
</div>
<p><button type="submit">Connect to Twitter</button></p>
</form>
最佳答案
您需要在 Twitter 的应用程序设置中设置回调 URL - 这应该在 Spring 指南中说明。
例如，我的应用程序使用此回调 url:
http://127.0.0.1:3000/auth/twitter/callback
它在输入字段的正下方解释:
Callback URL: Where should we return after successfully authenticating? OAuth 1.0a applications should explicitly specify their oauth_callback URL on the request token step, regardless of the value given here. To restrict your application from using callbacks, leave this field blank.
关于java - 为什么我使用 Spring Boot/Spring Social 指南示例获得到 Twitter 的空连接？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/31682351/
