用穷举列表解析JSON结果

[英]Parsing a JSON Result with exhaustive list

Good day, i am trying to parse this JSONObject returned from the OpenWeatherMap forecast API. 美好的一天,我正在尝试解析从OpenWeatherMap预报API返回的JSONObject。 this is the link link here 这是这里的链接

now it returns an exhaustive list of results and i just want to get the results for each day at rough 12:00 with the key "dt_txt". 现在,它返回了详尽的结果列表,我只想使用“ dt_txt”键在大约12:00每天获取每天的结果。 i was thinking of something like parsing only the dates and comparing with a date method that increments the current day in a loop and if it matches, i then parse the values for that day. 我正在考虑只解析日期,然后与日期方法进行比较的方法,该方法将循环增加当前日期,如果匹配,则解析该天的值。 But i wanted to know if there is a better, faster and more efficient solution to achieve this. 但是我想知道是否有更好,更快和更有效的解决方案来实现这一目标。 Many thanks. 非常感谢。

Have you tested how long a simple new JSONObject(textFromYourLink) takes? 您是否测试了一个简单的new JSONObject(textFromYourLink)需要多长时间? Is it even necessary to optimize the speed? 甚至有必要优化速度吗?

If there is actually, some need for optimization, I'd suggest that you do some pre-processing of the text and, using some regular expressions, get rid of the parts you don't need. 如果确实存在一些优化需求,我建议您对文本进行一些预处理,并使用一些正则表达式来摆脱不需要的部分。 After that, you still can convert the remaining string to a JSONObject which should be done faster now. 之后,您仍然可以将剩余的字符串转换为JSONObject ,现在应该更快地完成此操作。
