我正在尝试构建GraphQL服务器,并尝试使用GraphiQL Chrome扩展程序来进行游戏。
只要我将端点设置为我的服务器http://localhost:3000/graphql,GraphiQL就会发送一个空查询:
Request URL:http://localhost:3000/graphql
Request Method:POST
Status Code:200 OK
Remote Address:[::1]:3000
Referrer Policy:no-referrer-when-downgrade
我让它返回一个空响应,但是,我在Chrome中遇到了这个JavaScript错误:
react.min.js:14 Uncaught TypeError: Cannot read property 'length' of undefined
at GraphiQL.autoCompleteLeafs (chrome-extension://fkkiamalmpiidkljmicmjfbieiclmeij/ext/graphiql/graphiql.js:1060:33)

at Object.processEventQueue (chrome-extension://fkkiamalmpiidkljmicmjfbieiclmeij/ext/react.min.js:12:19721)
之后,GraphiQL根本不起作用。我可以输入任何查询,单击播放按钮,它所做的只是重复错误:
答案 0 :(得分:1)
我相信GraphiQL chrome扩展需要来自API的对象响应。尝试在emtpy请求中返回一个空白对象,看看是否能解决它。
在提交空白请求时查看https://launchpad.graphql.com(也使用GraphiQL),我得到以下对象:
{
"code": 400,
"error": "Script returned an error.",
"details": "No query was provided in request body."
}
这是一个可用于调试的描述性响应。
