道具类型失败：提供给“SignUp”的“object”类型的无效道具“params”，应为“array”

Question

如果我将其设置为接收数组，则会收到此 proptype 验证错误“Invalid prop”，然后它将显示预期的数组但接收对象，在其他情况下相同的错误预期函数但接收对象。 在 (signupData : PropTypes.object || PropTypes.array) 这个警告 与如果我只为 Object 设置 PropTypes 然后错误有关 是“object 类型的无效道具 params”和 如果为 Array 设置 PropTypes 则错误为“ Invalid prop params 类型为 object"。任何机构都有解决方案？

Answer 1

当你写 signupData : PropTypes.object || PropTypes.array 时，你基本上是在说

if(PropTypes.object){
   return PropTypes.object;
} else {
   return PropTypes.array;
}

换句话说，由于PropTypes.object 将始终评估为true，因此您一直将您的道具声明为PropTypes.object。

如果您想针对多个类型验证道具，请使用oneOfType

  // An object that could be one of many types
  optionalUnion: PropTypes.oneOfType([
    PropTypes.string,
    PropTypes.number,
    PropTypes.instanceOf(Message)
  ])
