graphql server端有更新，client端需要重新获取schema文件用于创建新的api request，下面简要记录如何从graphql endpoint获取schema文件
You can simply install the CLI using npm or yarn by running the following command. This will add the graphql (and shorter gql) binary to your path.
npm install -g graphql-cli
Then, you can type [command] just like bellow to create a file named .graphqlconfig
You can get schema like this.
Ops! Now specific headers is needed. We open .graphqlconfig file to edit it.
Pay attention to edit this file, since it's very important to the result.
At last, we get the damn schema.json by graphql get-schema --output="schema.json"
Done.
Happy Mid-Autumn Festival !
