如何在GraphQL服务器上接受来自远程服务器的POST请求

type Mutation {
  sendPostRequest(url: String!, headers: [String: String], body: String!): PostResponse
}

type PostResponse {
  statusCode: Int
  headers: [String: String]
  body: String
}

const { graphql, buildSchema } = require('graphql');
const axios = require('axios');

// 定义GraphQL schema
const schema = buildSchema(`
  type Mutation {
    sendPostRequest(url: String!, headers: [String: String], body: String!): PostResponse
  }

  type PostResponse {
    statusCode: Int
    headers: [String: String]
    body: String
  }
`);

// 定义GraphQL resolver
const root = {
  sendPostRequest: async ({ url, headers, body }) => {
    try {
      const response = await axios.post(url, body, { headers });
      return {
        statusCode: response.status,
        headers: response.headers,
        body: response.data
      };
    } catch (error) {
      throw new Error('Failed to send POST request to remote server');
    }
  }
};

// 运行GraphQL查询
const runQuery = async (query) => {
  const result = await graphql(schema, query, root);
  console.log(result);
};

// 示例查询
const query = `
  mutation {
    sendPostRequest(
      url: "https://example.com/api",
      headers: {
        "Content-Type": "application/json",
        "Authorization": "Bearer token"
      },
      body: "{\\"key\\": \\"value\\"}"
    ) {
      statusCode
      headers
      body
    }
  }
`;

runQuery(query);
