我试图在react-native中设置一个android应用程序,它正在调用本地API。 理想情况下,我希望看到API请求实际上成功,或者至少返回一个格式化的GraphQL异常,该异常应在后端生成。
我的GraphQL api在localhost:3000上运行
我已经为遇到的任何问题尝试了通用解决方案
我已经像这样设置了ApolloClient
const client = new ApolloClient({
link: new HttpLink({
uri: Platform.select({
android: 'http://"my machine ip here" / ipv4 /graphql'
})
}),
cache: new InMemoryCache(),
});
我也尝试过
const client = new ApolloClient({
link: new HttpLink({
uri: Platform.select({
android: 'http://10.0.2.2:3000/graphql'
})
}),
cache: new InMemoryCache(),
});
在此处发出API请求:
const [login, {data, loading, error}] = useMutation(LoginUserMutation);
return <LoginWrapper>
<Formik
initialValues={{email: '', password: ''}}
onSubmit={async ({email, password}) => {
const user = await login({variables: {email, password}});
}}
>
{({
values,
handleChange,
errors,
setFieldTouched,
touched,
isValid,
handleSubmit
}) => <>
<Input
value={values.email}
onChangeText={handleChange('email')}
onBlur={() => setFieldTouched('email')}
placeholder='E-mail'
/>
<Input
value={values.password}
onChangeText={handleChange('password')}
placeholder='Password'
onBlur={() => setFieldTouched('password')}
secureTextEntry={true}
/>
<Button
onClick={handleSubmit}
text='Sign In'
/>
</>}
</Formik>
</LoginWrapper>
};
在这里可以看到graphql突变
export const LoginUserMutation =
gql(
mutation('loginUser',
params(
{
$args: 'LoginUserInput!'
},
{
updateUser: params({args: '$args'},
{
email: types.string,
}
),
})
)
);

答案 0 :(得分:0)
所以我解决了这个问题。
突变应该是
export const LoginUserMutation = gql(
mutation('login',
params({$args: 'LoginUserInput!'}, {
login: params({args: '$args'}, {
token: types.string,
}),
})
)
);
突变的呼唤应该是
const [login, {data, loading, error}] = useMutation(LoginUserMutation);
await login({variables: {args: {email, password}}})
