我在我的React Native应用程序上使用GraphQL和Apollo,我的查询运行正常,但是当我尝试运行突变(在浏览器上使用完全相同的代码)时,我得到以下内容错误:
Error: Network error: Response not successful: Received status code 400
at new ApolloError (bundle.umd.js:76)
at bundle.umd.js:952
at bundle.umd.js:1333
at Array.forEach (<anonymous>)
at bundle.umd.js:1332
at Map.forEach (<anonymous>)
at QueryManager.broadcastQueries (bundle.umd.js:1327)
at bundle.umd.js:901
at tryCallOne (core.js:37)
at core.js:123
以下是我尝试发送此突变的方法:
const createItem = gql`{
mutation {
createItem(title: "Banana", summary: "Santa", campaignId: 1, pinId: 1) {
id
}
}
}`;
client.query({query: createItem}).then((resp) => {
console.log('query answer');
console.log(resp);
}).catch((error) => {
console.log('error');
console.log(error);
});
这是我的客户:
import { ApolloClient } from 'apollo-client';
import { HttpLink } from 'apollo-link-http';
import { setContext } from 'apollo-link-context';
import { InMemoryCache } from 'apollo-cache-inmemory';
let bearer_token = '';
const httpLink = new HttpLink({ uri: 'http://localhost:3000/graphql/' });
const authLink = setContext((_, { headers }) => {
// get the authentication token from local storage if it exists
const token = bearer_token;
// return the headers to the context so httpLink can read them
return {
headers: {
...headers,
authorization: token ? `Bearer ${bearer_token}` : "",
}
}
});
const client = new ApolloClient({
link: authLink.concat(httpLink),
cache: new InMemoryCache()
});
export function setToken(token) {
bearer_token = token;
}
export default client;
在后端,我调试并收到请求,它根据客户端上设置的令牌找到用户,但后来什么也没做,只返回我,只有当我尝试从应用程序,在graphiql浏览器上运行。
我错过了什么?非常感谢你。
答案 0 :(得分:0)
正如丹尼尔指出的那样,我的gql有一个额外的括号,但这不是问题,我实际应该使用mutate
函数而不是query
。该文档显示了query
的示例,但我找不到mutate
的任何内容,因此存在混淆。
const createItem = gql`
mutation {
createItem(title: "Banana", summary: "Santa", campaignId: 1, pinId: 1) {
id
}
}`;
使用它:
client.mutate({mutation: createItem}).then((resp) => {
console.log(resp)
}).catch((error) => {
console.log(error)
});
希望这有助于其他GraphQL初学者!
