Question

我使用Mongo DB连接器将数据插入位于mLab的Mongo Instance。我确信我正在使用正确的凭据，因为当我通过Java代码使用它们时这些凭据正在工作。但是在这里使用Mongo DB连接器会不断地向我发出错误，如下所示。

org.mule.api.ConnectionException：无法与给定的连接凭证org.mule.api.ConnectionException：无法连接给定的凭证在 org.mule.module.mongo.MongoCloudConnector.getDatabase（MongoCloudConnector.java:1304）在 org.mule.module.mongo.MongoCloudConnector.connect（MongoCloudConnector.java:1173）在 org.mule.module.mongo.connectivity.MongoCloudConnectorConnectionFactory.makeObject（MongoCloudConnectorConnectionFactory.java:56）在 org.apache.commons.pool.impl.GenericKeyedObjectPool.borrowObject（GenericKeyedObjectPool.java:1220）在 org.mule.module.mongo.connectivity.MongoCloudConnectorConnectionManager.acquireConnection（MongoCloudConnectorConnectionManager.java:361）在 org.mule.module.mongo.connectivity.MongoCloudConnectorConnectionManager.test（MongoCloudConnectorConnectionManager.java:444）在 org.mule.tooling.metadata.api.utils.ConnectionTester.internalTestConnection（ConnectionTester.java:88）在 org.mule.tooling.metadata.api.utils.ConnectionTester.testConnectionFor（ConnectionTester.java:113）在

我在这里缺少什么东西吗？

MongoDB连接器使用不推荐使用的MONGODB-CR身份验证机制，MLab期待SCRAM-SHA-1机制。

SCRAM-SHA-1机制在Mulesoft ESB的企业版中可用。

4.2.1版及更高版本提供了连接URI配置。这是你配置它的方式：

将连接器添加到pom.xml：

def lps(s):
    print(s)
    n = len(s)
    if n <= 1:
        return n

    if s[0] == s[n-1]:
        return 2 + lps(s[1:-1])
    return max(lps(s[:-1]), lps(s[1:]))

在您的流程中配置连接：
