我正在使用 luasec、lua-socket执行对外部 API 的请求,并将数据(JSON 字符串)转换为带有cjson的 lua 表。我已经阅读了上述模块的文档,不幸的是,这些文档都没有帮助我解决我的问题。不能用当前帐户链接超过 2 个网站,抱歉。
摘要:我使用发布的请求函数获得响应和适当的字符串,当通过 cjson.decode 将所述字符串转换为 lua 表时,输出表不是所需的,它是我的响应标头的副本,这不是故意的.
以下代码是我执行请求的方式:
local function request (req_t)
local res_t = {}
resp = https.request {
url = const.API_URL .. req_t.url,
method = req_t.method,
headers = req_t.headers,
sink = ltn12.sink.table(res_t)
}
return table.concat(res_t), resp.headers, resp.code
end
使用以下调用
local res, headers = request({ ... })
我收到作为字符串的正确响应,但我的目标是使用它进行数据操作,因此将所述响应(字符串)转换为 lua 表
local resJson = cjson.decode(res)
不会产生正确的输出。它确实生成了一个与我的响应标头完全相同的表。这是我的终端的以下输出以及代码
When out of function type is: string
Desired response in string:
{"total_photos":221926,"photo_downloads":"186029632.0"}
When out of function type is: string
Desired response in string:
{"total_photos":221926,"photo_downloads":"186029632.0"}
After decode, type is: table

产生所述日志的函数
local res, headers = request({ ... })
print('When out of function type is: ' ..type(res) .. '\n')
print('Desired response in string:')
print(res .. '\n')
resJson = cjson.decode(res)
print('\nAfter decode, type is: ' .. type(resJson) .. '\n')
pTable(resJson)
print('\nPrinting header\n')
pTable(headers)
pTable 只是一个将表格输出到标准输出的函数。
