Question

最近，我正在将我的应用程序从Symfony 3.4升级到Symfony 4.2。我在告诉read error on connection时遇到错误。

这是堆栈跟踪：

这可能会有所帮助。以前我的配置是这样的：

snc_redis:
    clients:
        default:
            type: predis
            alias: default
            dsn: "%redis_dsn%"
            options:
                read_write_timeout: "%redis_read_write_timeout%"
        session:
            type: phpredis
            alias: session
            dsn: "%redis_dsn%"
            options:
                read_write_timeout: "%redis_read_write_timeout%"
        doctrine:
            type: phpredis
            alias: doctrine
            dsn: "%redis_dsn%"
            options:
                read_write_timeout: "%redis_read_write_timeout%"
    session:
        client: session
        prefix: session:main

    doctrine:
        metadata_cache:
            client: doctrine
            entity_manager: default          # the name of your entity_manager connection
            document_manager: default        # the name of your document_manager connection
            namespace: "%kernel.root_dir%"
        result_cache:
            client: doctrine
            entity_manager: [default, read]  # you may specify multiple entity_managers
        query_cache:
            client: doctrine
            entity_manager: default

更改为以下内容

snc_redis:
    clients:
        default:
            type: predis
            alias: default
            dsn: "%redis_dsn%"
            options:
                read_write_timeout: "%redis_read_write_timeout%"
        session:
            type: predis
            alias: session
            dsn: "%redis_dsn%"
            options:
                read_write_timeout: "%redis_read_write_timeout%"
        doctrine:
            type: predis
            alias: doctrine
            dsn: "%redis_dsn%"
            options:
                read_write_timeout: "%redis_read_write_timeout%"
    session:
        client: session
        prefix: session:main

    doctrine:
        metadata_cache:
            client: doctrine
            entity_manager: default          # the name of your entity_manager connection
            document_manager: default        # the name of your document_manager connection
            namespace: "%kernel.root_dir%"
        result_cache:
            client: doctrine
            entity_manager: [default, read]  # you may specify multiple entity_managers
        query_cache:
            client: doctrine
            entity_manager: default
