Prisma绑定无法连接到prisma服务器。请求到http：//localhost：4466/失败，原因：连接ECONNREFUSED127.0.0.1:4466

我正在运行两个单独的docker服务。一个用于我的GraphQL服务器，另一个用于棱镜服务，该服务连接到本地Postgres数据库。我能够运行Arizona部署并直接在中进行测试http://localhost:4466。但是，当我尝试使用中的应用程序的GraphQL服务器进行查询时http://localhost:8080，它将给出以下响应。

{
  "data": null,
  "errors": [
    {
      "message": "request to http://localhost:4466/ failed, reason: connect ECONNREFUSED 127.0.0.1:4466",
      "locations": [
        {
          "line": 2,
          "column": 3
        }
      ],
      "path": [
        "feed"
      ]
    }
  ]
}

这是堆栈跟踪。

这就是我创建绑定的方式

const server = new GraphQLServer({
  typeDefs: './src/schema.graphql',
  resolvers,
  context: req => ({
    ...req,
    db: new Prisma({
      typeDefs: './src/generated/prisma.graphql',
      endpoint: 'http://localhost:4466',
      secret: 'my-secret',
      debug: true,
    })
  })
});

我不确定是什么问题。

得到了prisma论坛的帮助以解决此问题。

在容器中使用localhost指向容器本身，而不是容器运行所在的主机。因此，为了连接到Prisma实例，您必须使用内部服务名称，该名称解析为相应的Prisma容器。

...
    db: new Prisma({
      typeDefs: './src/generated/prisma.graphql',
      endpoint: 'http://prisma:4466',
      secret: 'my-secret',
      debug: true,
    })
...
