如何使用 jsonbuilder 制作一个 json，它有一个名为 DefaultGroovyMethods 方法（身份）的键？

Question

def builder = new groovy.json.JsonBuilder()
        def root = builder.auth {
            identity {
                    methods (['password'])
                    password {
                        user {
                            name {
                                usrName
                                domain {
                                    id usrDomain
                                }
                                password "openstack"
                            }
                        }
                    }
                    scope {
                        project {
                            name prjName
                            domain {
                                id 'default'
                            }
                        }
                    }
                }
            }
        assert builder.toString() == '{"auth":{"identity":{"methods":["password"],"password": {"user":{"name":"admin","domain":{"id":"default"},"password":"openstack"}}},"scope":{"project":{"name":"admin","domain":{"id":"default"}}}}}'

断言输出：

    Assertion failed: 

    assert builder.toString() == '{"auth":{"identity":{"methods":["password"],"password": {"user":{"name":"admin","domain":{"id":"default"},"password":"openstack"}}},"scope":{"project":{"name":"admin","domain":{"id":"default"}}}}}'
           |       |          |
           |       |          false
           |       '{"auth":{"methods":["password"],"password":{"user":{"name":{"domain":{"id":"Default"},"password":"openstack"}}},"scope":{"project":{"name":"admin","domain":{"id":"default"}}}}}'
           {"auth":{"methods":["password"],"password":{"user":{"name":{"domain":{"id":"Default"},"password":"openstack"}}},"scope":{"project":{"name":"admin","domain":{"id":"default"}}}}}

基本上 "identity" 键被忽略了。我看到有一个名为 "identity" 的方法属于 DefaultGroovyMethods，但我不知道如何克服它。第一次写Groovy，有点背景Python。感谢任何帮助！

使用 Szymon Stepniak 的回答完成的完整解决方案（以及对 json 声明的其他更正）：

def builder = new groovy.json.JsonBuilder()
    builder auth: [
            identity: {
                methods(['password'])
                password {
                    user {
                        name "$usrName"
                        domain {
                            id usrDomain
                        }
                        password "openstack"

                    }
                }
            },
            scope: {
                project {
                    name prjName
                    domain {
                        id 'default'
                        }
                    }
            }
                ]
    assert builder.toString() == '{"auth":{"identity":{"methods":["password"],"password":{"user":{"name":"admin","domain":{"id":"default"},"password":"openstack"}}},"scope":{"project":{"name":"admin","domain":{"id":"default"}}}}}'

以防万一有人想跟随这个例子。

要克服此限制（传递给 JsonBuilder.call() 方法的闭包解析委托链中的 identity 方法），您需要将 JSON 文档表示为地图或在至少使用映射到 identity 键，从这个地方你可以使用闭包。

def builder = new groovy.json.JsonBuilder()

builder auth: [
    identity: {
        methods (['password'])
        password {
            user {
                name {
                    usrName
                    domain {
                        id usrDomain
                    }
                    password "openstack"
                }
            }
        }
        scope {
            project {
                name prjName
                domain {
                    id 'default'
                }
            }
        }
    }
]

此外，请记住，您定义的闭包不会生成预期的 JSON 字符串，但它会包含闭包示例中缺少的 identity 键。
