正如 @bwaindwain 提到的 toArray() 方法代替 getBody() 起作用。

toArray() 方法适用于以下格式的响应:

[
    {
      "token": "4354iojegdjss"
    }
]

但是,使用这种响应格式,所有键仍然消失:

{
      "token": "4354iojegdjss"
 }

我对此问题的解决方法是在 src/api/resources/posts.json 中手动添加 responseModel,如下所示:

{
  "operations": {
    "GetToken": {
      "httpMethod": "POST",
      "uri": "token",
      "summary": "Get token",
      },
      "responseModel": "Token"
  }
}

 "models": {
    "Token": {
      "type": "object",
      "location": "json",
      "properties": {
        "token": {
          "location": "json",
          "type": "string"
        }
       }
    }
 }

如果有人知道更好的解决方案,请发表评论。
