我正在尝试向/graphiql
IDE发出请求,并且收到有关我的来源的超时错误。
ERRO [0515]向源发送请求时出错。这意味着原始GraphQL服务器没有及时响应代理请求。若要解决此问题,请验证引擎配置中的Origin规范与相应的GraphQL服务器匹配。如果错误是超时错误,请考虑在引擎配置中增加
origin.requestTimeout
。错误=“发布http://127.0.0.1:51301/graphql:net / http:请求已取消(在等待标题时超出了Client.Timeout)” url =“ http://127.0.0.1:51301/graphql”
请记住,每次运行时url(http://127.0.0.1:51301/graphql)端口都会更改,因此这使我相信它必须是apollo引擎代理正在运行的url,因为服务器上的任何内容都不会更改端口号,例如那。
我的阿波罗引擎配置就是这样
import { ApolloEngine } from "apollo-engine";
import { ENGINE_API_KEY, PORT } from "../config/keys";
import { INFO } from "./utils/logging";
import app from './app';
const LOG_START = () => INFO(`Listening! at port: ${PORT}`);
/*
setup Apollo Engine
*/
const engine = new ApolloEngine({
apiKey: process.env.ENGINE_API_KEY || ENGINE_API_KEY,
});
/*
Config for Apollo Engine to serve
*/
const ENGINE_SERVE = {
port: PORT,
graphqlPaths: ["/graphql"],
expressApp: app,
launcherOptions: {
startupTimeout: 3000
}
};
/*
Entry point for application starts server
*/
engine.listen(ENGINE_SERVE, LOG_START);
我的端口号是:8080
我的Apollo服务器是这样设置的
import cors from "cors";
import morgan from "morgan";
import express from "express";
import bodyParser from "body-parser";
import compression from "compression";
import { graphqlExpress, graphiqlExpress } from "apollo-server-express";
import connectDb from "./connectors/mongo-connector";
import schema from "./schemas/schema";
/*
Create express application
*/
const app = express();
/*
Configure graphql server
*/
const GRAPH_EXPRESS = graphqlExpress({
schema,
tracing: true,
context: { db: async () => await connectDb() }
});
/*
Configure Graphql IDE for testing
*/
const GRAPH_IDE = graphiqlExpress({ endpointURL: "/graphql" });
/*
Middleware and route handlers
*/
app.use(cors());
app.use(morgan("dev"));
app.use(compression());
app.use("/graphql", bodyParser.json(), GRAPH_EXPRESS);
app.use("/graphiql", GRAPH_IDE);
export default app;
我不明白为什么我尝试过的请求没有被退回
增加我的起点超时,并在引擎配置中显式设置我的起点。但是由于端口每次更改,我无法设置错误消息指出的URL,所以我有点不知所措,我们将不胜感激。
"origins": [
{
"http": {
"requestTimeout": "60s",
"url": "http://localhost:8080/graphql",
"overrideRequestHeaders": {
"Host": "localhost"
}
}
}
]
答案 0 :(得分:0)
问题是我的mongo连接器没有通过没有mongo连接而触发,我的端点未超时,并且我误解了错误的含义。
const GRAPH_EXPRESS = graphqlExpress({
schema,
tracing: true,
context: { db: connectDb() }
});
