Karate API GraphQL POST示例：创建用户后查询参数传递问题求助

问题根因 #

• 第二个GraphQL查询语句中的变量占位符存在语法错误：你写的#(userID'缺少了占位符要求的右闭合括号)，非法的查询语句直接触发GraphQL解析报错。
• 额外注意：如果你的服务端getUser接口的id参数定义为数值类型而非字符串类型，需要删除占位符外层的双引号，避免后续出现参数类型不匹配的错误。

修正后的测试代码 #

Scenario: Create a User
Given path 'query'
And header Accept = 'application/json'
Given text query = 
"""
mutation {
  createUser(username: "CreateUser16"
, name: "Auto CreateUser", isPrivate: true) {
        id
        username
        lastLoginAt
        createdAt
      }
    }

"""

And request { query: '#(query)' }
When method POST
Then status 200
And print response
And match response.data.createUser.id !=null
* def userID = response.data.createUser.id
And print userID
Given path 'query'
And header Accept = 'application/json'
Given text query = 
"""
{
  getUser(id: '#(userID)') {
    bio
    birthDate
    createdAt
    id
  }
}
"""

And request { query: '#(query)' }
When method POST
Then status 200
And print response
