我需要向graphql端点发出自己的请求。 (默认实现使POST调用我们指定的url)。我需要进行一次AJAX调用。我从以下读到: http://dev.apollodata.com/core/network.html#custom-network-interface
它明确指出我需要创建一个NetworkInterface并将其传递给ApolloClient。
我做了类似的事情:
const customInterface = {
query(request) {
return $.post(url_of_graphql_endpoint)
.send({query : request.query.loc.source.body})
.end()
.then(result => result.text)
}
}
const client = new ApolloClient({networkInterface: customInterface});
ReactDOM.render((
<ApolloProvider client={client}>
<Router history={browserHistory}>
<Route path='/' component={App} />
</Router>
</ApolloProvider>
),
document.getElementById('root')
)
正在向graphql端点发出网络请求,服务器也会响应apt响应(它应该发送)。
即使在此之后,我的浏览器出现了一些错误,因为我无法显示从我的服务器获取的数据。组件始终处于“加载”状态。

我能够覆盖查询方法的功能,所以我只是为可能面临同样问题的其他人发布答案。
我试图覆盖查询方法的方式是错误的。我是这样做的。
class CustomNetworkInterface extends HttpNetworkInterface{
query(request){
return $.post(url_of_graphql_endpoint)
.send({query : request.query.loc.source.body})
.end()
.then(result => result.text)
}
}
为了制作ApolloClient,只需传入CustomNetworkInterface的对象。
const client = new ApolloClient({networkInterface: new CustomNetworkInterface(http://url)});
ReactDOM.render((
<ApolloProvider client={client}>
<Router history={browserHistory}>
<Route path='/' component={App} />
</Router>
</ApolloProvider>
),
document.getElementById('root')
)
