【问题描述】：
我知道一个非常通用的标题，我的问题是我在 lua 中编码并且我正在尝试做一个 string.gsub 但它似乎没有找到我的模式。在下面找到所有详细信息。任何帮助表示赞赏。

string.gsub(msg, '"querystring":{}', '"querystring":{'..BuildURLParameters()..'}')
string.gsub(msg, '},"headers":{','},"body":{'..BuildBodyParameters()..'},"headers":{')

【问题讨论】：
-
首先：最好只是JSON解码，添加数据并再次JSON编码。其次： string.gsub 不会像您想象的那样忽略空格（如换行符）。例如
'"querystring":{}'应该是'"querystring":{%s*}'以使其也计算换行符。 -
@EinsteinK 好的，我明白了。尽管如果数据不是 JSON 格式，我必须查看数据的结构（表格等）。天真地，这些数据来自 nginx。
