Question

我需要从以下数据中显示每个对象（响应）的object_id。

这是我通过Api获得的答复。建议或解决方案都将受到赞赏。

response:{"object_id":"a9951ef0","datetime":"2019-03-20T04:59:23.001Z","ignition_status":"ON"}

response:{"object_id":"8b1546924063","datetime":"2019-03-20T04:59:23.001Z","ignition_status":"OFF"}

response:{"object_id":"9b9d","datetime":"2019-03-20T04:59:23.001Z","ignition_status":"ONLINE"}

预期输出：

object_id = a9951ef0
object_id = 8b1546924063
object_id = 9b9d

Answer 1

我假设您有3种不同的响应，其中包含公用密钥，并且您想从中获取公用密钥的值

如果正确，则可以使用流。

将json响应转换为对象列表

[
  "response1",
  "response2",
  "response3"
]

arrayList = new Gson().fromJson(<above json>, ArrayList.class)

然后您可以使用流获取期望值

arrayList.stream.map(<arraylistType> :: <keyName>).collect(Collectors.toList());

Answer 2

您的API返回的是字符串JSON。您需要将其“ parse”放入JavaScript对象，然后可以简单地通过所需键访问该值。

const parsedResponse = JSON.parse(response);
console.log(parsedResponse.object_id);

Answer 3

以下逻辑可能有效。伪代码中的示例。无法直接工作。

# real_response is your message from API.
# Convert it into array by splitting newlines. Use different separator if needed.
responses_in_array = real_response.split("\n");

# Loop through every responses.
foreach(single_response in responses_in_array) {

    # Clean responses before converting them into javascript objects.
    clean_response = single_response.replace("response:", "");
    real_object = JSON.Parse(clean_response);

    // Do what ever you want. To access object_id, just call
    // real_object.object_id.
    //
    // If needed, before cleaning line, check if it's not empty line.
}

解决了解析消息的基本逻辑后，您可以找到帮助您的更好方法或内置函数。
