Prisma绑定无法连接到prisma服务器。请求http://localhost:4466/失败，原因:连接ECONNREFUSED 127.0.0.1:4466

Question

我在经营两个独立的码头服务。一个用于我的GraphQL服务器，另一个是连接到本地Postgres数据库的prisma服务。我能够在http://localhost:4466中直接运行prisma部署并测试它。但是当我试图在http://localhost:8080中使用我的应用程序的http://localhost:8080服务器进行查询时，它会给出以下响应。

{
  "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。

graphql-server_1  |     at fulfilled (/usr/src/app/node_modules/graphql-binding/node_modules/graphql-tools/dist/stitching/delegateToSchema.js:4:58)

我就是这样创建绑定的

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,
    })
  })
});

我不知道问题出在哪里。

从prisma论坛那里得到了解决这个问题的帮助。

在容器中使用localhost指向容器本身，而不是运行容器的主机。因此，为了连接到Prisma实例，您必须使用内部服务名称，它解析为相应的Prisma容器。

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

这发生在我在windows上使用Docker时，必须将端点从使用本地主机更改为prisma.yml中的prisma.yml默认ip

endpoint: http://192.168.99.100:4466
