GraphQL客户端订阅无法正常工作(React Js)
componentDidMount = async () => {
const subscriptionDeleteProduct = API.graphql(graphqlOperation(SubscribeProductDelete)).subscribe({
next: (eventData) =>{
this.handleSubscriptionDelete(eventData)},
error:(error)=>{
console.log('error',error)
}
});
const subscriptionCreateProduct = API.graphql(graphqlOperation(SubscribeProductCreate)).subscribe({
next: (eventData) => {console.log('subscriptionCreateProduct');
},
error:(error)=>{
console.log('error',error)
}
});
const subscriptionUpdateProduct = API.graphql(graphqlOperation(SubscribeProductUpdate)).subscribe({
next: (eventData) => {this.handleSubscriptionUpdate(eventData)},
error:(error)=>{
console.log('error',error)
}
});
}
某些组件订阅创建和删除,他们工作,但订阅更新不起作用 我检查AWS AppSync上的查询,它的工作原理 对于创建代码,我已经检查了Appsync,并且该过程正常工作。
如何解决问题?
