在ruby graphql-client中转义GraphQL查询中的字符串变量？

require 'graphql/client'
require 'graphql/client/http'

# 定义GraphQL查询字符串
query_string = <<~GRAPHQL
  query($stringValue: String!) {
    search(value: $stringValue) {
      results
    }
  }
GRAPHQL

# 创建一个GraphQL::Client实例
client = GraphQL::Client.new(schema: YourSchema, execute: YourExecutor)

# 创建一个GraphQL::Client::HTTP实例，设置GraphQL API的访问地址
http_client = GraphQL::Client::HTTP.new('https://your-graphql-api-url.com/endpoint')

# 配置GraphQL::Client实例的HTTP客户端
client.http = http_client

# 定义GraphQL查询
query = client.parse(query_string)

# 定义查询变量
variables = { stringValue: 'Your string value' }

# 执行GraphQL查询
result = client.query(query, variables: variables)

# 输出查询结果
puts result.data.search.results
