我正在尝试console.log
使用 authLink 函数,但没有看到任何控制台日志输出。就好像函数本身从未被调用过。
任何人都知道为什么我在 authLink 中调用它时看不到任何 console.log 输出?
import { ApolloClient } from "apollo-client";
import { useQuery } from "@apollo/react-hooks";
import { InMemoryCache } from "apollo-cache-inmemory";
import { createHttpLink } from "apollo-link-http";
import { setContext } from "apollo-link-context";
import AsyncStorage from "@react-native-community/async-storage";
import { resolvers, typeDefs } from "./resolvers";
const cache = new InMemoryCache();
const httpLink = createHttpLink({
uri: "https://foobar"
});
const authLink = setContext(async (_, { headers }) => {
console.log("In here!");
let authToken = await AsyncStorage.getItem("authToken");
if (authToken !== null) {
cache.writeData({
data: {
isLoggedIn: true,
authToken: authToken,
},
});
} else {
cache.writeData({
data: {
isLoggedIn: false,
authToken: "",
},
});
}
return {
headers: {
...headers,
authorization: authToken ? `Bearer ${authToken}` : "",
},
};
});
const client = new ApolloClient({
cache: cache,
link: authLink.concat(httpLink),
typeDefs: typeDefs,
resolvers: resolvers,
});
export default client;
