我编写了一个Python脚本,将数据发送到apache webserver,数据很好地到达$ _POST和$ _FILES aray。现在我想在Lua中实现同样的东西,但我还不能实现它。
我在Python中的代码看起来像这样:
try:
wakeup()
socket.setdefaulttimeout(TIMEOUT)
opener = urllib2.build_opener(MultipartPostHandler.MultipartPostHandler)
host = HOST
func = "post_img"
url = "http://{0}{1}?f={2}&nodemac={3}&time={4}".format(host, URI, func, nodemac, timestamp)
if os.path.isfile(filename):
data = {"data":open(filename,"rb")}
print "POST time "+str(time.time())
response = opener.open(url, data, timeout=TIMEOUT)
retval = response.read()
if "SUCCESS" in retval:
return 0
else:
print "RETVAL: "+retval
return 99
except Exception as e:
print "EXCEPTION time "+str(time.time())+" - "+str(e)
return 99
到目前为止我提出的Lua代码:
#! /usr/bin/lua
http = require("socket.http")
ltn12 = require("ltn12")
http.request{
url = "localhost/test.php?test=SEMIOS",
method = "POST",
headers = {
["Content-Type"] = "multipart/form-data; boundary=127.0.1.1.1000.17560.1375897994.242.1",
["Content-Length"] = 7333
},
source = ltn12.source.file(io.open("test.gif")),
sink = ltn12.sink.table(response_body)
}
print(response_body[1]) --response to request
但是这段代码让我在执行时得到了这个:
$ ./post.lua
/usr/bin/lua: ./post.lua:17: attempt to index global 'response_body' (a nil value)
stack traceback:
./post.lua:17: in main chunk

有几个使用Lua发送POST数据的示例:from the author of luasocket和SO。 This example直接与文件一起使用,这与您正在使用的文件非常接近。
