我尝试使用Apollo Client向非Apollo GraphQL服务器发出请求,如下所示:
import ApolloClient, { createNetworkInterface } from 'apollo-client';
// Register gql globally
import { registerGqlTag } from 'apollo-client/gql';
registerGqlTag();
const networkInterface = createNetworkInterface(' http://localhost:8080/graphql', {
headers: {
'Content-type': "application/json"
}
});
var client = new ApolloClient({
networkInterface
});
client.query({
query: gql`
query getTodo($todoId: Int!) {
node(id: $todoId) {
... on Todo {
id
text
}
}
}
`,
variables: {
todoId: "todo:100000",
},
forceFetch: false,
}).then((graphQLResult) => {
var errors = graphQLResult.errors;
var data = graphQLResult.data;
if (data) {
console.log('got data', data);
}
if (errors) {
console.log('got some GraphQL execution errors', errors);
}
}).catch((error) => {
console.log('there was an error sending the query', error);
});
但是我在运行代码时遇到错误:
there was an error sending the query [ReferenceError: fetch is not defined]
我尝试搜索与此相关的问题,但文档并没有真正帮助。
先谢谢。

在幕后,Apollo客户端使用fetch
这是围绕发出http请求的新标准。它存在于大多数主流浏览器中,但在节点或IE / Edge中找不到它。该团队致电fetch,因为它的采用率正在增长,并且旧版浏览器和节点的polyfill可用。
我们在此处针对此问题的文档添加了一个部分:http://docs.apollostack.com/apollo-client/core.html#fetch-polyfill
要了解有关获取提取的决定,请查看此问题:https://github.com/apollostack/apollo-client/pull/126

如果您在节点环境中工作,则需要将提取添加到Error in setup_twitter_oauth(consumerKey, consumerSecret, access_token, :
could not find function "setup_twitter_oauth"
对象:
