Neo4j 2.2、密码和ROR错误- UsersController#try_login中的未授权错误

Question

刚刚从2.1升级到2.2..系统提示您将密码添加到neo4j。是不是..。图形看起来很好..但是现在我的rails应用程序，它使用了新的Gem，将不能连接。

我得到了这个错误：

UsersController#try_login中的未授权错误

我已将代码更改为

@neo = Neography::Rest.new("http://neo4j:neo4j!@localhost:7474")

但它不起作用。

已将初始化文件更改为

Neography.configure do |config|
  config.protocol       = "http://"
  config.server         = "localhost"
  config.port           = 7474
  config.directory      = ""  # prefix this path with '/' 
  config.cypher_path    = "/cypher"
  config.gremlin_path   = "/ext/GremlinPlugin/graphdb/execute_script"
  config.log_file       = "neography.log"
  config.log_enabled    = false
  config.max_threads    = 20
  config.authentication = nil  # nil 'basic' or 'digest'
  config.username       = "neo4j"
  config.password       = "neo4j!"
  config.parser         = MultiJsonParser
end

这也不起作用(不用担心密码被更改了)

以前我从来没有在Neo上使用过密码，但在这个新版本中，我使用了密码，现在我的应用程序无法连接。我没有安装任何证书，并且正在使用任何形式的身份验证。

我可以在登录后使用正确的密码连接到web管理员，但我无法通过我的应用程序成功连接。

有什么我没注意到的吗？我需要安装证书吗？在OS 10.7.5、Rails 3.2.11、Ruby ruby 1.9.3p429、webrick和Neography Gem上工作。

更新:我是从rails控制台运行的：

@neo = Neography::Rest.new("http://neo4j:neo4j@localhost:7474")

然后回来了

=> #<Neography::Rest:0x007fe04a8ff9d0 @connection=#<Neography::Connection:0x007fe04a8ff7f0 @protocol="http://", @server="localhost", @port=7474, @directory="", @cypher_path="/cypher", @gremlin_path="/ext/GremlinPlugin/graphdb/execute_script", @log_file="neography.log", @log_enabled=false, @max_threads=20, @parser=MultiJsonParser, @user_agent={"User-Agent"=>"Neography/1.0.9"}, @authentication={:basic_auth=>{:username=>"neo4j", :password=>"neo4j"}}, @client=#<HTTPClient:0x007fe04a906640 @proxy=nil, @no_proxy=nil, @no_proxy_regexps=[], @www_auth=#<HTTPClient::WWWAuth:0x007fe04a906438 @basic_auth=#<HTTPClient::BasicAuth:0x007fe04a906410 @cred=nil, @set=false, @auth={}, @challengeable={}, @scheme="Basic">, @digest_auth=#<HTTPClient::DigestAuth:0x007fe04a906118 @auth={}, @challenge={}, @set=false, @nonce_count=0, @scheme="Digest">, @negotiate_auth=#<HTTPClient::NegotiateAuth:0x007fe04a906050 @auth={}, @auth_default=nil, @challenge={}, @scheme="Negotiate", @set=false, @ntlm_opt={:ntlmv2=>true}>, @ntlm_auth=#<HTTPClient::NegotiateAuth:0x007fe04a905f38 @auth={}, @auth_default=nil, @challenge={}, @scheme="NTLM", @set=false, @ntlm_opt={:ntlmv2=>true}>, @sspi_negotiate_auth=#<HTTPClient::SSPINegotiateAuth:0x007fe04a905e48 @challenge={}, @scheme="Negotiate">, @oauth=#<HTTPClient::OAuth:0x007fe04a905d80 @config=nil, @auth={}, @challengeable={}, @nonce_count=0, @signature_handler={"HMAC-SHA1"=>#<Method: HTTPClient::OAuth#sign_hmac_sha1>}, @scheme="OAuth">, @authenticator=[#<HTTPClient::OAuth:0x007fe04a905d80 @config=nil, @auth={}, @challengeable={}

然后我尝试创建一个节点：

@neo.create_node

并接收到

Answer 1

很奇怪..。这对我很有效。

2.2.0 :003 > @neo = Neography::Rest.new("http://neo4j:swordfish@localhost:7474")

@neo.create_node

{"extensions"=>{}, "outgoing_relationships"=>"http://localhost:7474/db/data/node/0/relationships/out", "labels"=>"http://localhost:7474/db/data/node/0/labels", "traverse"=>"http://localhost:7474/db/data/node/0/traverse/{returnType}", "all_typed_relationships"=>"http://localhost:7474/db/data/node/0/relationships/all/{-list|&|types}", "self"=>"http://localhost:7474/db/data/node/0", "property"=>"http://localhost:7474/db/data/node/0/properties/{key}", "properties"=>"http://localhost:7474/db/data/node/0/properties", "outgoing_typed_relationships"=>"http://localhost:7474/db/data/node/0/relationships/out/{-list|&|types}", "incoming_relationships"=>"http://localhost:7474/db/data/node/0/relationships/in", "create_relationship"=>"http://localhost:7474/db/data/node/0/relationships", "paged_traverse"=>"http://localhost:7474/db/data/node/0/paged/traverse/{returnType}{?pageSize,leaseTime}", "all_relationships"=>"http://localhost:7474/db/data/node/0/relationships/all", "incoming_typed_relationships"=>"http://localhost:7474/db/data/node/0/relationships/in/{-list|&|types}", "metadata"=>{"id"=>0, "labels"=>[]}, "data"=>{}} 

你能确认你的代码中没有"Neography::Rest.new“吗？

Answer 2

您可以允许在不进行身份验证的情况下进行访问(尽管这当然不太安全)。

变化

dbms.security.auth_enabled=true

至

dbms.security.auth_enabled=false

在文件中

conf/neo4j-server.properties
