【问题描述】：

我正在尝试通过 gremlin 控制台 3.3.4 连接到 cosmos db，在此之后 remote_secure.yaml 如下：

hosts: [*****.gremlin.cosmosdb.azure.com]
port: 443
username: /dbs/sample-database/colls/sample-collection
password: ******
connectionPool: {
  enableSsl: true}
{ className: org.apache.tinkerpop.gremlin.driver.ser.GraphSONMessageSerializerV1d0, config: { serializeResultToString: true }}:

但是当我运行:remote connect tinkerpop.server conf/remote-secure.yaml

我收到以下错误

==>Error during 'connect' - Can't construct a java object 
for tag:yaml.org,2002:org.apache.tinkerpop.gremlin.driver.Settings;
exception=Keys must be scalars but found:

(tag=tag:yaml.org,2002:str, value=config)>; value=828088650 })>
in 'reader', line 27, column 1:
hosts: [*****.gremlin.cosm ...

任何想法我做错了什么？

【解决方案1】：

看起来您的配置被破坏了。您在最后一行缺少 serializer 键：

hosts: [*****.gremlin.cosmosdb.azure.com]
port: 443
username: /dbs/sample-database/colls/sample-collection
password: ******
connectionPool: {
  enableSsl: true}
serializer: { className: org.apache.tinkerpop.gremlin.driver.ser.GraphSONMessageSerializerV1d0, config: { serializeResultToString: true }}

是的，就是这样。谢谢
