Transactions Neo4jClient事务-事务完成时的身份验证错误
我正在尝试使用最新的Neo4jClient事务支持预发行版(Neo4jClient 1.1.0-Tx00008)。我尝试了最简单的示例,但似乎每次事务完成时都会出现身份验证错误(Neo4j Community 2.2.2或2.3)。以下代码:Transactions Neo4jClient事务-事务完成时的身份验证错误,transactions,neo4jclient,Transactions,Neo4jclient,我正在尝试使用最新的Neo4jClient事务支持预发行版(Neo4jClient 1.1.0-Tx00008)。我尝试了最简单的示例,但似乎每次事务完成时都会出现身份验证错误(Neo4j Community 2.2.2或2.3)。以下代码: var graphClient = new GraphClient(new Uri("http://user:password@localhost:7474/db/data")); graphClient.Connect()
var graphClient = new GraphClient(new Uri("http://user:password@localhost:7474/db/data"));
graphClient.Connect();
using (var transaction = graphClient.BeginTransaction())
{
graphClient.Cypher.Create("(n:TestNode {Name:'TestNode2'})").ExecuteWithoutResults();
graphClient.Cypher.Create("(n:TestNode {Name:'TestNode3'})").ExecuteWithoutResults();
transaction.Commit();
}
在调用事务提交时,或者如果我排除了transaction.commit()
并允许范围结束,则始终会导致此错误:
Received an unexpected HTTP status when executing the request.
The response status was: 401 Unauthorized
The response from Neo4j (which might include useful detail!) was: <html>
<head><title>401 Authorization Required</title></head>
<body bgcolor="white">
<center><h1>401 Authorization Required</h1></center>
<hr><center>nginx</center>
</body>
</html>
执行请求时收到意外的HTTP状态。
响应状态为:401未经授权
Neo4j的回应(可能包括有用的细节!)是:
401需要授权
401需要授权
nginx
在不使用任何事务作用域的情况下,可以很好地创建节点。我已经查看了源代码中的单元测试,但在如何调用它方面没有发现任何区别。目前您必须使用AuthWrapper,我担心它会像:
private class HttpClientAuthWrapper : IHttpClient
{
private readonly AuthenticationHeaderValue _authenticationHeader;
private readonly HttpClient _client;
public HttpClientAuthWrapper(string username, string password)
{
_client = new HttpClient();
if (string.IsNullOrWhiteSpace(username) || string.IsNullOrWhiteSpace(password))
return;
var encoded = Encoding.ASCII.GetBytes(string.Format("{0}:{1}", username, password));
_authenticationHeader = new AuthenticationHeaderValue("Basic", Convert.ToBase64String(encoded));
}
public Task<HttpResponseMessage> SendAsync(HttpRequestMessage request)
{
if(_authenticationHeader != null)
request.Headers.Authorization = _authenticationHeader;
return _client.SendAsync(request);
}
}
这将使所有事务使用正确的身份验证头。感谢您在Github上提出这个问题-我们可以研究如何妥善解决它

var client = new GraphClient(
new Uri("http://localhost.:7474/db/data"),
new HttpClientAuthWrapper("user", "pass#")
);
client.Connect();
