给出以下graphql模式
# graphql/schema.graphql
type AppUser {
userId: String
fullName: String
}
type Query {
getUser(userId: String): AppUser
getUsers(): [AppUser]
}
type Mutation {
addUser(user: AppUser!): AppUser
}
以及以下在lib / mystack.ts中定义的cdk代码:
const graphql = new appsync.GraphQLApi(this, 'GraphQLApi', {
name: 'metrolens-graphql-api',
logConfig: {
fieldLogLevel: appsync.FieldLogLevel.ALL,
},
authorizationConfig: {
defaultAuthorization: {
// userPool,
defaultAction: appsync.UserPoolDefaultAction.ALLOW,
},
// additionalAuthorizationModes: [{ apiKeyDesc: 'My API Key' }],
},
schemaDefinitionFile: props?.schemaDirectory,
})
const lambdaRegister = new nodejs.NodejsFunction(this, 'register', {
functionName: 'register',
runtime: lambda.Runtime.NODEJS_12_X,
timeout: cdk.Duration.seconds(10),
entry: './lambda/register/register-0.ts',
handler: 'handler',
layers: [layer],
description: 'Register a user.',
})
const lambdaLogin = new nodejs.NodejsFunction(this, 'login', {
functionName: 'login',
runtime: lambda.Runtime.NODEJS_12_X,
timeout: cdk.Duration.seconds(10),
entry: './lambda/login/login-0.ts',
handler: 'handler',
layers: [layer],
description: 'Login a user.',
})
const lambdaRegisterDataSource = graphql.addLambdaDataSource(
'lambdaRegister',
'Register lambda triggered by appsync',
lambdaRegister
)
lambdaRegisterDataSource.createResolver({
typeName: 'Mutation',
fieldName: 'addUser',
requestMappingTemplate: appsync.MappingTemplate.lambdaRequest(),
responseMappingTemplate: appsync.MappingTemplate.lambdaResult(),
})
const lambdaLoginDataSource = graphql.addLambdaDataSource(
'lambdaLogin',
'Login lambda triggered by appsync',
lambdaLogin
)
lambdaLoginDataSource.createResolver({
typeName: 'Query',
fieldName: 'getUsers',
requestMappingTemplate: appsync.MappingTemplate.lambdaRequest(),
responseMappingTemplate: appsync.MappingTemplate.lambdaResult(),
})
我在AWS::AppSync::GraphQLSchema
部署阶段收到以下错误消息:
[GraphQLApi / Schema(GraphQLApiSchema5937B126)架构创建状态为FAILED,详细信息:保存架构时发生内部故障。
以前有人遇到此错误吗?我怀疑我的graphql模式有问题,但是我无法确定它是什么。另一个答案提到,即使您不使用DynamoDB,位于https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/ReservedWords.html的DynamoDB保留字也可能导致冲突,因此我将User
类型重命名为AppSync
。但是,看起来Query
也是保留字,但据我了解,这对于graphql定义也是必需的。请帮忙。 AWS CDK很难吸。
将getUsers(): [AppUser]
更新为getUsers: [AppUser]
我遇到了同样的错误,并将我的架构插入验证器中,发现了错误。
