Question

我正在使用luasec lua-socket向外部API执行请求，并将数据（JSON字符串）转换为带cjson的lua表。我已经阅读了所述模块的文档，不幸的是，它没有帮助我解决我的问题。无法使用当前帐户链接超过2个网站，抱歉。

总结：我使用发布的请求函数得到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，它是我的响应头的副本，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

使用以下电话

local res, headers = request({ ... })

我收到正确的字符串响应，但我的目标是用它来进行数据操作，所以将响应（字符串）转换为带有

的lua表

local resJson = cjson.decode(res)

不是否会产生正确的输出。它确实生成一个与我的响应头完全相同的表。以下是我的终端以及代码

的输出

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只是一个将表输出到stdout的函数。

提前致谢

Answer 1

发布功能和例程是正确的。问题出在我的打印表函数中，我以某种方式对我的标题进行了硬编码。

JSON字符串无法转换为正确的Lua表
