Facebook4j API：搜索 [英] Facebook4j API : Search

问题描述

我使用Facebook4j获取与关键字状​​态

I'm using Facebook4j to get status with a keyword

 facebook4j.conf.ConfigurationBuilder fac = new facebook4j.conf.ConfigurationBuilder();

            fac.setDebugEnabled(true)
              .setOAuthAppId("******")
              .setOAuthAppSecret("********")
              .setOAuthPermissions("email,publish_stream,...");
            FacebookFactory ff = new FacebookFactory(fac.build());
           facebook = ff.getInstance();
           new Thread(new Runnable() { 
               @Override
               public void run() {
                   try {
                       search();
                   }
                   catch (Exception e) {
                    // TODO: handle exception
                       System.out.println(e +" ERROOOOOOR");
                }}}).start();
}
//search
public void search() throws Exception {
         ResponseList<JSONObject> results = facebook.search("%23morocco");
         System.out.println(results);
         for (JSONObject result : results) {
             System.out.println(result);
         }

         results = facebook.search("orange", new Reading().until("yesterday"));
         System.out.println(results);
         for (JSONObject result : results) {
             System.out.println(result);
         }
     }

我取代的 * 的与Facebook的API密钥
我有一个例外probleme，错误的是：
java.lang.IllegalStateException：没有可用的令牌。 ERROOOOOOR

I replaced * with facebook api key I have a exception probleme , the error is : java.lang.IllegalStateException: No Token available. ERROOOOOOR

推荐答案

您忘了设定访问令牌fac.setOAuthAccessToken（*****） 。从文档（重点煤矿）：

You forgot to set the access token with fac.setOAuthAccessToken("*****"). From the docs (emphasis mine):

所有的图形API搜索查询需要访问令牌通过与的access_token =＆LT;令牌GT; 参数。访问令牌，你需要的类型取决于搜索你执行的类型。

All Graph API search queries require an access token passed in with the access_token=<token> parameter. The type of access token you need depends on the type of search you're executing.

  
• 横渡页和地方对象搜索需要的应用程序访问令牌。

  
• 所有其它端点需要用户访问令牌

  

• Searches across page and place objects requires an app access token.
• All other endpoints require a user access token.

您可以生成一个自己这里，但请记住，这些访问令牌具有过期时间。

You can generate one for yourself here, but remember that these access tokens have an expiration time.
