我是AWS lambda和GraphQL的新手。我正在尝试将Express GraphQL应用程序部署到AWS Lambda。
index.js文件
object demo
{
def main(args:Array[String]):Unit=
{
val temp: LinkedHashMap[String,Object]=new
LinkedHashMap[String,Object]()
temp.put("apple", new Double(1));
// here i received error since double is abstract class and cannot instantitaed
}
}
但是在AWS Lambda控制台中执行AWS Lambda函数时出错。
const awsServerlessExpress = require("aws-serverless-express");
var express = require("express");
var graphqlHTTP = require("express-graphql");
var { buildSchema } = require("graphql");
// Construct a schema, using GraphQL schema language
var schema = buildSchema(`
type Query {
hello: String
}
`);
// The root provides a resolver function for each API endpoint
var root = {
hello: () => {
return "Hello world!";
}
};
var app = express();
app.use(
"/",
graphqlHTTP({
schema: schema,
rootValue: root,
graphiql: true
})
);
const server = awsServerlessExpress.createServer(app);
exports.handler = (event, context) =>
awsServerlessExpress.proxy(server, event, context);
Expected Output:

您的服务器很好。我认为问题是您的查询。它以某种方式变形。由于您未包括在内,因此我们无法确定。但是,如果您的请求带有
,则可能会得到更好的结果Content-Type: 'application/graphql'
或
Content-Type: 'application/json'
,然后使请求正文看起来像这样:
{"query": "{hello}" }
请注意引号的位置;如果是JSON,则必须采用类似JSON的格式。
