[英]Using Variables with react-apollo Query
I've attached a query to my React Native component like so: 我已经将查询附加到我的React Native组件上,如下所示:
let getNearbyStoriesQuery = gql`{
getStoriesNearbyByGeoHash(geoHash: "8k"){
id
}
}`;
export default graphql(getNearbyStoriesQuery,
{
props: (props) => {
debugger;
let storiesNearby = props.data.getStoriesNearbyByGeoHash.map((story) => {
return {
id: story.id,
}
});
return {storiesNearby};
},
variables: {
geoHash: mockGeoHash
}
})(Home); // Home is the React Native Component
I'm able to retrieve data from using this technique as long as I hardcode a value in for geoHash in the query; 只要我在查询中为geoHash硬编码一个值,就可以使用这种技术来检索数据; in this case I used "8k".
在这种情况下,我使用“ 8k”。 However, when I attempt to modify the query so that I can puss in a variable like so:
但是,当我尝试修改查询以便可以像这样输入变量时:
let getNearbyStoriesQuery = gql`{
getStoriesNearbyByGeoHash($geoHash: String!){
id
}
}`;
I get an error saying Expected Name, found $
. 我收到一个错误消息,说
Expected Name, found $
。 This method of passing variables to queries is repeated across multiple sources. 在多个源之间重复使用这种将变量传递给查询的方法。 What am I doing wrong here?
我在这里做错了什么?
Should be: 应该:
query GetStoriesNearbyByGeoHash($geoHash: String!) {
getStoriesNearbyByGeoHash(geoHash: $geoHash){
id
}
}
