Ansible合并json对象

我需要根据第一个对象键合并两个JSON对象

object1 = {
 "params" : {
    "type": ["type1", "type2"],
    "requeststate": []
 }        
}

object2 = {
 "params" : {
    "type": ["type2", "type3", "type4"],
    "requeststate": ["Original", "Revised" ],
    "responsestate": ["Approved" ]
 }        
}

我需要根据第一个对象键合并两个对象，我的输出应该如下所示

mergedobject = {
 "params" : {
    "type": ["type1", "type2", "type3", "type4"],
    "requeststate": ["Original", "Revised"]
 }        
}

我找了我的案子，没有找到太多细节 请让我知道是否可以使用ansible

我可以将数组与

  set_fact:
    mergedrequeststate: "{{ object1.params.requeststate +  object2.params.requeststate  }}"

但是我的案例涉及15个以上的params对象，我不能声明所有的param对象。此外，它可能会在未来增长，我需要处理，如果可能的话

如果您需要更多详细信息，请发表评论。 感谢您的支持

使用过滤器

---

需求描述得很好，我只想补充一点，您希望合并键，并从两个对象中获得

唯一的

值（如果不是这样，请注意下面PB中的

联合

过滤器）。此外，您的示例变量假定我们希望合并

objectX.params

下的键

没有进一步的到期，这里是一个PB，将让你去。有一个调试步骤来显示

object1的所有键。params

有一个循环来合并两个对象的值，然后是最终打印

PB：

执行结果：
