我正在使用react-apollo和graphql-tag,但似乎失败了。服务器正在快递和邮递上运行。
我做错什么了吗?
{
"query": "{\n allPosts(first:10) {\n nodes {\n \tnodeId,\n id,\n content\n }\n }\n}"
}
反应(失败);
Status Code: 400 Bad Request
Response: {"errors":[{"message":"Must provide a query string."}]}
代码:
export const allPostsQuery = gql`
{
allPosts(first: 10) {
nodes {
nodeId,
id,
content
}
}
}
`;
. . .
<Query query={ allPostsQuery }> . . . </Query>
生成的请求有效负载将相应地显示:
{"operationName":null,"variables":{},"query":"{\n allPosts(first: 10) {\n nodes {\n nodeId\n id\n content\n __typename\n }\n __typename\n }\n}\n"}
我还尝试通过Postman运行此有效负载,看起来一切正常。
这是我的Apollo客户端配置:
return new ApolloClient({
connectToDevTools: process.browser,
ssrMode: !process.browser,
link: new HttpLink({
uri: 'http://127.0.0.1:8181/graphql',
credentials: 'include',
headers: {
'Content-Type': 'application/json'
}
}),
cache: new InMemoryCache().restore(initialState || {})
});
答案 0 :(得分:0)
感谢@azium,我知道了。再次非常感谢。 Content-Type
正在复制自身:
Request Headers -> content-type: application/json, application/json
function create (initialState) {
return new ApolloClient({
connectToDevTools: process.browser,
ssrMode: !process.browser,
link: new HttpLink({
uri: 'http://127.0.0.1:8181/graphql',
credentials: 'include'
// headers:
// 'Content-Type': 'application/json' <-- remove the duplicate
//}
}),
cache: new InMemoryCache().restore(initialState || {})
});
}
