GitHub的新GraphQL API需要使用令牌作为先前版本进行身份验证。那么,我们如何在Apollo-Client
内的HttpLink中添加“Header”信息?
const client = new ApolloClient({
link: new HttpLink({ uri: 'https://api.github.com/graphql' }),
cache: new InMemoryCache()
});
您可以使用apollo-link-context
定义授权标头,检查the header section
使用apollo-client for Github API的完整示例如下:
import { ApolloClient } from 'apollo-client';
import { HttpLink } from 'apollo-link-http';
import { setContext } from 'apollo-link-context';
import { InMemoryCache } from 'apollo-cache-inmemory';
import gql from 'graphql-tag';
const token = "YOUR_ACCESS_TOKEN";
const authLink = setContext((_, { headers }) => {
return {
headers: {
...headers,
authorization: token ? `Bearer ${token}` : null,
}
}
});
const client = new ApolloClient({
link: authLink.concat(new HttpLink({ uri: 'https://api.github.com/graphql' })),
cache: new InMemoryCache()
});
client.query({
query: gql`
query ViewerQuery {
viewer {
login
}
}
`
})
.then(resp => console.log(resp.data.viewer.login))
.catch(error => console.error(error));
