graphql server端有更新，client端需要重新獲取schema文件用於創建新的api request，下面簡要記錄如何從graphql endpoint獲取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 !
