OpenResy+Lua 利用百度识图 将图片地址解析成文字
LUA代码：（注：LUA里有一个调用百度识图的接口IP:123.125.115.189(stu.baidu.com)，不知为什么我的虚拟机无法解析stu.baidu.com，所以我只能PING出IP来用。）location /test {content_by_lua ' local request_method = ngx.var.request_method;local args = nil;if "GET" == request_method thenargs = ngx.req.get_uri_args();elsengx.req.read_body();args = ngx.req.get_post_args();endlocal imageUrl = args["imageUrl"]function Split(szFullString, szSeparator)local nFindStartIndex = 1local nSplitIndex = 1local nSplitArray = {}while true dolocal nFindLastIndex = string.find(szFullString, szSeparator, nFindStartIndex)if not nFindLastIndex thennSplitArray = string.sub(szFullString, nFindStartIndex, string.len(szFullString))breakendnSplitArray = string.sub(szFullString, nFindStartIndex, nFindLastIndex - 1)nFindStartIndex = nFindLastIndex + string.len(szSeparator)nSplitIndex = nSplitIndex + 1endreturn nSplitArrayendlocal cjson = require "cjson"local http = require "resty.http"local hc = http:new()local ok, code, headers, status, body= hc:request { url = "http://123.125.115.189/n/pc_search?queryImageUrl="..imageUrl,method = "GET", -- POST or GET }local _,aaa = string.find(body,"keywords:\'")local bbb = string.find(body,"|default")local ccc = string.sub(body,aaa+2,bbb-2) ngx.say(tostring(ccc)) ';}
