本文整理了Java中org.json.JSONObject.optLong()方法的一些代码示例，展示了JSONObject.optLong()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。JSONObject.optLong()方法的具体详情如下：
包路径：org.json.JSONObject
类名称：JSONObject
方法名：optLong

JSONObject.optLong介绍

[英]Returns the value mapped by name if it exists and is a long or can be coerced to a long. Returns 0 otherwise. Note that JSON represents numbers as doubles, so this is lossy; use strings to transfer numbers via JSON.
[中]返回按名称映射的值（如果该值存在且为long或可以强制为long）。否则返回0。请注意，JSON将数字表示为双精度，因此这是lossy；使用字符串通过JSON传输数字。
