小编ser*_*403的帖子

在我的rails应用程序中,我使用oauth来访问用户的配置文件数据.事情是当Instagram的授权登录页面弹出时,用户必须输入他的登录详细信息,cookie将保存在我的机器中.有没有办法删除这个cookie(显然不是手动)？我问这个是因为当再次调用oauth页面时,保存在浏览器中的这个cookie会自动登录用户.这已成为我项目的麻烦.我不希望这种情况发生,我希望再次显示相同的登录页面.

我试图找到一种方法来保持我的mysql数据库和elasticsearch数据库同步.我使用jprante/elasticsearch-river-jdbc插件为elasticsearch设置了一个jdbc河.当我执行以下请求时:

curl -XPUT 'localhost:9200/_river/my_jdbc_river/_meta' -d '{
"type" : "jdbc",
"jdbc" : {
    "driver" : "com.mysql.jdbc.Driver",
    "url" : "jdbc:mysql://localhost:3306/MY-DATABASE",
    "user" : "root",
    "password" : "password",
    "sql" : "select * from users",
    "poll" : "1m"
},
"index" : {
    "index" : "test_index",
    "type" : "user"
}
}'

河流开始索引数据,但对于一些记录我得到org.elasticsearch.index.mapper.MapperParsingException.那么有关于这一问题的讨论在这里,但我想知道的方式来解决这个问题.

是否可以通过为我要编制索引的"类型"的所有"字段" 创建显式映射来永久修复此问题,或者是否有更好的方法来解决此问题？

我的另一个问题是,当jdbc-river再次轮询数据库时,它似乎将整个数据集(在sql查询中给出)重新索引到ES中.我不确定,但是这样做是因为elasticsearch想要添加新数据以及更新现有数据中的任何更改吗？如果表的数据是静态的,是否可以仅索引新数据？

每当我启动我的节点时，我都会收到此错误。怎么了？

我使用jdbc河将mysql表数据的所有记录(半百万条记录)索引到elasticsearch中.一切都进行得很好,然后突然河流开始抛出一些奇怪的索引错误,无论何时它试图索引文档.

错误:

这就是我通常在fbml f-connect标签中指定重定向URL的方式

<fb:login-button onlogin='redirect-url'>f-connect</fb:login-button>

如何在登录时指定重定向网址:

<div class="fb-login-button">f-connect</div> ??

我正在尝试使用linkedin ruby​​ api向API端点发送消息:http://api.linkedin.com/v1/people/~/shares但每次我收到此错误:LinkedIn::Errors::AccessDeniedError ((403): Access to posting shares denied).怎么了？

码:

#fetch client object
client = LinkedIn::Client.new('er0xev11ktyj', 'qw7hfgR4wT8Hztpl')

#auth
request_token = client.request_token(:oauth_callback => callback_url)
session[:linkedin_token] = request_token.token
session[:linkedin_secret] = request_token.secret
redirect_to request_token.authorize_url

#inside callback url
atoken,asecret = client.authorize_from_request(session[:linkedin_token], session[:linkedin_secret], params[:oauth_verifier])

#api call for posting message
client.authorize_from_access(atoken, asecret)
client.add_share({:comment => "Hey!"}) #throws error!

我需要指定范围参数吗？如果是,我如何在我的代码中实现这一点？

谢谢

是否可以将jquery源代码中的名称"jQuery"更改为其他名称.我想用这个新名称执行我的jQuery操作.
例如: jQuery('#something').attr();要 myName('#something').attr(); 我怎么做呢？
