javascript - Angular - 将 Jackson 输出转换为 JSON

Question

我正在使用的服务器更改了纯 JSON 的 REST 格式:

    {           
        "removedVertices": [
            {
                "id": "1",
                "info": {
                    "host": "myhost",
                    "port": "1111"
                },
                "name": "Roy",
                "type": "Worker"
            }
        ],
        "id": "2",
        "time": 1481183401573
    }

jackson 格式:

    {
          "removedVertices": [
          "java.util.ArrayList",
           [
                   {
                         "id": "1",
                          "info": [
                                "java.util.HashMap",
                                {
                                    "host": "myhost",
                                    "port": "1111"
                                }
                         ]
                         "name": "Roy",
                         "type": "Worker",                             
                    }                       
            ]
            "id": "2",
            "time": 1482392323858
    }

如何像以前在 Angular/Javascript 中那样解析它？

假设只有数组受到影响，我会使用 underscore.js并编写一个递归函数来删除 Jackson 类型。

function jackson2json(input) {
  return _.mapObject(input, function(val, key) {
    if (_.isArray(val) && val.length > 1) {
      // discard the Jackson type and keep the 2nd element of the array
      return val[1];   
    }
    else if (_.isObject(val)) {
      // apply the transformation recursively
      return jackson2json(val);
    }
    else {
      // keep the value unchanged (i.e. primitive types)
      return val;
    }
  });
}
