У меня есть приложение на Vuejs и функция, которая загружает анкету через graphQL. Функция прекрасно работает, пока я не добавлю variables к запросу.
Рабочий код функции:
downloadQuestionnaire() {
console.log("downloadQuestionnaire: " + questionnaireVersion);
this.$apollo
.query({
query: gql`
query questionnaire {
questionnaire(inputParams: { language: "en", version: 1 }) {
sections {
section
cssClass
remainingItemsType
endingMessageText
questions {
qId
label
question
inputType
possibleAnswers {
paId
text
}
multipleAnswersAccepted
individualFormat
answers
}
}
}
}
`,
client: "questionnaire",
variables: {
version: questionnaireVersion
}
})
.then(data => {
// this.sections = data.questionnaire;
// console.log(data);
this.copyQuestionnaie(data.data.questionnaire.sections);
// console.log(JSON.stringify(data.data.questionnaire.sections));
})
.catch(error => {
this.error = error;
alert("E " + error);
});
},
и мне нужно параметризовать version в запросе, изменив его на:
downloadQuestionnaire() {
console.log("downloadQuestionnaire: " + questionnaireVersion);
this.$apollo
.query({
query: gql`
query questionnaire($version: Int) {
questionnaire(
inputParams: { language: "en", version: $version }
) {
sections {
section
cssClass
remainingItemsType
endingMessageText
questions {
qId
label
question
inputType
possibleAnswers {
paId
text
}
multipleAnswersAccepted
individualFormat
answers
}
}
}
}
`,
client: "questionnaire",
variables: {
version: 1
}
})
.then(data => {
// this.sections = data.questionnaire;
// console.log(data);
this.copyQuestionnaie(data.data.questionnaire.sections);
// console.log(JSON.stringify(data.data.questionnaire.sections));
})
.catch(error => {
this.error = error;
alert("E " + error);
console.log("ERROR: " + error);
});
},
И тогда я получаю ошибку:
RROR: Error: Network error: Response not successful: Received status code 400
Я пытался использовать тот же синтаксис, что и в примере здесь .
Я неправильно ввожу параметры или наблюдаю за опечаткой?
