Question

在Python 2.7中，我正在创建一个包含未答复线程列表的json字符串（api调用返回）。我现在拥有它的方式，每个线程都是一个数组元素。这对我没有任何问题。但我正在努力改进我的编码，我想知道这个json字符串是否正确组织/格式化还是可以改进它的格式？

{
   "unanswered_threads":[
      {
         "thread_id":174,
         "author_username":"BP",
         "latest_post_date":"2014-02-18T03:37:21.67",
         "latest_reply_author":684,
         "url":"https://community.com/products/t/334.aspx",
         "reply_count":2,
         "forum_id":18,
         "author_name":"ABP",
         "subject":"Storage App"
      },
      {
         "thread_id":335,
         "author_username":"wigv",
         "latest_post_date":"2014-02-18T02:13:29.183",
         "latest_reply_author":649,
         "url":"https://community.com/products/t/375.aspx",
         "reply_count":2,
         "forum_id":45,
         "author_name":"wigsv",
         "subject":"configuration - RPC-2.1"
      }
   ]
}

这就是我生成这个json字符串的方式：

threads =  r.json()["Threads"]
thread_batch = []

for thread in thread_generator(threads):
    thread_batch.append(thread)

json_return = json.dumps({ "unanswered_threads": thread_batch });

JSONlint说这是有效的。我通常会得到更接近这一点的东西：

{
    "unanswered_threads": [{
        "thread_id": 174,
            "author_username": "BP",
            "latest_post_date": "2014-02-18T03:37:21.67",
            "latest_reply_author": 684,
            "url": "https://community.com/products/t/334.aspx",
            "reply_count": 2,
            "forum_id": 18,
            "author_name": "ABP",
            "subject": "Storage App"
    }, {
        "thread_id": 335,
            "author_username": "wigv",
            "latest_post_date": "2014-02-18T02:13:29.183",
            "latest_reply_author": 649,
            "url": "https://community.com/products/t/375.aspx",
            "reply_count": 2,
            "forum_id": 45,
            "author_name": "wigsv",
            "subject": "configuration - RPC-2.1"
    }]
}

但差别很小：:之后的间距，并将}]放在一行上。

你能使用json module吗？然后你只需要将你的数据放入python字典并使用json.dump方法。

自定义Json字符串格式 - 这可以写得更好/改进吗？
