red*_* 87 11 javascript apollo reactjs graphql next.js
我正在将Next JS与Apollo结合使用,并在with-data HOC中使用以下配置对其进行了设置:
import { ApolloClient } from 'apollo-client';
import { InMemoryCache } from 'apollo-cache-inmemory';
import { HttpLink } from 'apollo-link-http';
import { onError } from 'apollo-link-error';
import { withClientState } from 'apollo-link-state';
import { getMainDefinition } from 'apollo-utilities';
import { ApolloLink, Observable, split } from 'apollo-link';
import { WebSocketLink } from 'apollo-link-ws';
import withApollo from 'next-with-apollo';
import { SubscriptionClient } from 'subscriptions-transport-ws';
import { endpoint, prodEndpoint, WSendpoint, WSprodEndpoint } from '../config';
import defaults from '../apollo-state/graphql/default-state';
import Mutation from '../apollo-state/resolvers/mutation-resolvers';
const wsClient = process.browser ? new SubscriptionClient(process.env.NODE_ENV === 'development' ? WSendpoint : WSprodEndpoint, {
reconnect: true,
}) : null;
function createClient({ headers }) {
const wsLink = process.browser ? new WebSocketLink(wsClient) : null;
const httpLink = new HttpLink({
uri: process.env.NODE_ENV === 'development' ? endpoint : prodEndpoint,
credentials: 'include',
})
const link = process.browser ? split(
// split based on operation type
({ query }) => {
const { kind, operation } = getMainDefinition(query);
return kind === 'OperationDefinition' && operation === 'subscription';
},
wsLink,
httpLink,
) : httpLink;
const cache = new InMemoryCache();
const request = async operation => {
const contextObj = {
fetchOptions: {
credentials: 'include'
},
headers
};
operation.setContext(contextObj);
};
const requestLink = new ApolloLink((operation, forward) =>
new Observable(observer => {
let handle;
Promise.resolve(operation)
.then(oper => request(oper))
.then(() => {
handle = forward(operation).subscribe({
next: observer.next.bind(observer),
error: observer.error.bind(observer),
complete: observer.complete.bind(observer),
});
})
.catch(observer.error.bind(observer));
return () => {
if (handle) handle.unsubscribe();
};
})
);
// end custom config functions
const apolloClient = new ApolloClient({
credentials: 'include',
ssrMode: !process.browser,
link: ApolloLink.from([
onError(({ graphQLErrors, networkError }) => {
if (graphQLErrors) {
console.log(graphQLErrors)
}
if (networkError) {
console.log(networkError)
}
}),
requestLink,
withClientState({
defaults, // default state
resolvers: {
Mutation // mutations
},
cache
}),
link
]),
cache
}); // end new apollo client
return apolloClient;
}
export { wsClient };
export default withApollo(createClient);

在本地,一切正常。我可以登录,当我访问该站点时它会自动登录,并且SSR没问题。但是,当我部署到Next或Heroku时,SSR不起作用。
我调查了这个问题,似乎这是一个常见的问题,即Cookie没有随请求一起发送:
https://github.com/apollographql/apollo-client/issues/4455
https://github.com/apollographql/apollo-client/issues/4190
https://github.com/apollographql/apollo-client/issues/4193
问题似乎在于Apollo配置的这一部分,其中有时未定义标头,因此未发送cookie:
const request = async operation => {
const contextObj = {
fetchOptions: {
credentials: 'include'
},
headers
};
operation.setContext(contextObj);
};

人们提到的一些解决方法是:如果标题存在,则手动设置cookie标题:
const request = async operation => {
const contextObj = {
fetchOptions: {
credentials: 'include'
},
headers: {
cookie: headers && headers.cookie
}
};
operation.setContext(contextObj);
};

上面对代码的修改修正了服务器端渲染,但是当我使用浏览器中已登录的cookie访问网站时,它将不再自动登录(它以我的初始方法自动登录,但不会在生产环境中执行SSR )
人们已经提到,这可能与Now或Heroku一起使用,即在部署应用程序后使用生成的URL中的子域,并使用自定义域来解决问题。我尝试使用自定义域,但是仍然遇到问题。我的域设置如下:
前端域:mysite.com后端域:api.mysite.com
这里有没有人遇到过这个问题并能够解决?
如果您发现我的配置有问题或我如何设置域,请告诉我。
您应该添加 cookies 选项,如下所示。请确保您的浏览器中有一个 cookie,即 csrftoken。它应该是可用的。希望它有效。
const 请求 = 异步操作 => {
常量 contextObj = {
获取选项:{
凭证:“包括”
},
//################ 在此更改 ##########
标题:{
...标头
}
饼干: {
...饼干
}
//########################################
};
操作.setContext(contextObj);
};
