我在我的web服務器上使用apollo-client與我的graphql服務器（也是apollo）進行通信。我有一個成功的查詢工作和正確檢索數據，但是當我嘗試突變時，我收到new ApolloError消息。相同的突變複製/粘貼到graphiql完美的作品。apollo-client服務器到服務器突變導致錯誤（查詢正常）
我檢查了我的graphql服務器上的CORS，它已啓用並正常運行。我從字面上複製並將代碼中的變體粘貼到我的graphiql編輯器中，並且按預期工作。
有人可以爲我解釋一些這方面的信息，或者指導我如何在我的graphql-server上看到更多信息，爲什麼我會收到400錯誤？
這裏是阿波羅錯誤

**** ****更新我 我apolloMiddleware前加入中間件CONSOLE.LOG的req.headers和req.body
req.headers -------
{
"accept": "*/*",
"content-type": "application/json",
"authorization": "JWT ",
"accept-encoding": "gzip,deflate",
"user-agent": "node-fetch/1.0 (+https://github.com/bitinn/node-fetch)",
"connection": "close",
"content-length": "585",
"host": "localhost:9000"
}
req.body -------
{
"query": "mutation updateTwitterAccessToken($data: TokenInput!) {\n updateTwitterToken(data: $data) {\n _id\n services {\n twitter {\n id\n __typename\n }\n token {\n token\n expires\n __typename\n }\n __typename\n }\n __typename\n }\n}\n",
"variables": {
"data": {
"accessToken": "000700000-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
"accessTokenSecret": "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
"_id": "yyyyyyyyyyyyyyyyy",
"service": "twitter",
"serviceId": "000700000"
}
},
"operationName": "updateTwitterAccessToken"
}
我打電話給client.mutate({ ... })從我的網絡服務器，但在req.body這裏，我設置這個：
req.body -------
{
"query": "mutation ..."
....
}
爲什麼它是"query": "mutation ..."而不是"mutation": "mutation ..."？
