我们已经实现了模式拼接,其中GraphQL服务器从两个远程服务器获取模式并将它们拼接在一起.当我们只使用Query和Mutations时,一切都运行正常,但现在我们有一个用例,我们甚至需要缝合订阅,远程模式已经通过它实现了auth.

我们很难搞清楚如何通过网关将connectionParams中收到的授权令牌从客户端传递到远程服务器.

这就是我们如何反省架构:

API网关代码:

const getLink = async(): Promise<ApolloLink> => {
const http = new HttpLink({uri: process.env.GRAPHQL_ENDPOINT, fetch:fetch})

const link = setContext((request, previousContext) => {
    if (previousContext
        && previousContext.graphqlContext
        && previousContext.graphqlContext.request
        && previousContext.graphqlContext.request.headers
        && previousContext.graphqlContext.request.headers.authorization) {
        const authorization = previousContext.graphqlContext.request.headers.authorization;
        return {
            headers: {
                authorization
            }
        }
    }
    else {
        return {};
    }
}).concat(http);

const wsLink: any = new WebSocketLink(new SubscriptionClient(process.env.REMOTE_GRAPHQL_WS_ENDPOINT, {
    reconnect: true,
    // There is no way to update connectionParams dynamically without resetting connection
    // connectionParams: () => …

我是Selenium的新手.我只想将密钥发送到用户名文本框并一次发送一个tab键,以便文本框可以检查用户名的可用性.

这是代码:

 driver.findElement(By.xpath("//label[text()='User Name:']/following::div/input")).sendKeys("UserName");
 driver.findElement(By.xpath("//label[text()='User Name:']/following::div/input")).sendKeys(Keys.TAB);

但是这个没有用.

请帮我.

我正在关注 https://www.graph.cool/docs/1.0/quickstart/backend/typescript/typescript-rohd6ipoo4 for graphcool 并且我收到错误

{
 "errors": [
  {
  "code": 3016,
  "requestId": "api:api:cjc7gf91e002v0180uq2hqace",
  "message": "Project not found: 'my-app@dev'"
}]}

用于查询和变异。我是 graphcool 的新手，所以不知道为什么会这样。我正在按照上述链接中提供的步骤进行操作。

Graphql 服务器：

const server = new GraphQLServer({
typeDefs: './src/schema.graphql',
resolvers,
context: req => ({
  ...req,
  db: new Graphcool({
  endpoint: 'http://localhost:60000/my-app/dev',
  secret: 'mysecret123',
    }),
  }),
})

$ graphcool info
Service Name: my-app

dev (cluster: `local`)

HTTP:       http://localhost:60000/my-app/dev
Websocket:  ws://localhost:60000/my-app/dev
