我正在使用luasec,lua-socket執行對外部API的請求,並將數據(JSON字符串)轉換爲的lua表。我已經閱讀了所述模塊的文檔,但不幸的是,沒有一篇文章幫助我解決了我的問題。無法鏈接超過2個網站與當前帳戶,對不起。JSON字符串無法轉換爲正確的Lua表
摘要:當通過cjson.decode將所述字符串轉換爲lua表時,我得到響應和相應的字符串,輸出表不是我們想要的,它是我的響應頭的副本,這不是故意的。
下面的代碼是我做了我的請求:
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
使用下面的調用
local res, headers = request({ ... })
我收到的字符串正確的反應,但我的目標是做數據處理與它的,所以將所述響應(串)的LUA表
local resJson = cjson.decode(res)
是否不是會產生正確的輸出。它確實產生了一個正確的表與我的響應標題相同。下面是從我的終端以下輸出旁邊的代碼
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

功能產生表示日誌
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只是輸出功能的表到stdout。
在此先感謝
我已經運行了您的代碼(由於缺少零件,Luar版本5.2,luasec,luasocket,luarocks中的lua-cjson也添加了缺少的零件和最少的編輯),並且它按預期工作。我建議用適當的方式調試它:使用調試器(ZBS或LDT)。 – Green
在ZBS的調試器中測試過它,它按預期工作。問題實際上是在我的打印表函數中有我的頭表硬編碼。除了我之外沒有什麼不對謝謝您的幫助 –
