Question

给定字符串：

wifi.setmode(wifi.STATION)
wifi.sta.config("ssid", "password")
wifi.sta.connect()

ledpen = 0
gpio.mode(ledpen, gpio.OUTPUT)
gpio.write(ledpen, gpio.HIGH)

pirsensorpen = 2

gpio.mode(pirsensorpen, gpio.INT, gpio.PULLUP)

function beweging() -- This function gets called when movement is detected
    print("PIR sensor detecteerde beweging")
    gpio.write(ledpen, gpio.LOW)
    roepIFTTT(1)
    tmr.alarm(0, 2000, tmr.ALARM_SINGLE, function()
        gpio.write(ledpen, gpio.HIGH)
    end)
end

function roepIFTTT(value1)
  -- Trigger flashbutton op IFTTT
  conn = nil
  conn = net.createConnection(net.TCP, 0)
  conn:on("receive", function(conn, payload) end)
  conn:connect(80,"maker.ifttt.com")
  conn:on("connection", function(conn, payload)
  conn:send("POST /trigger/pirsensor/with/key/API_KEY?value1="..value1.." HTTP/1.1\r\nHost: maker.ifttt.com\r\nConnection: keep-alive\r\nAccept: */*\r\n\r\n") end)
  conn:close()
  print("IFTTT is aangeroepen")



-- It is about the code below that generates the error. If there is another way if creating a simple HTTP GET request, it is welcome.
    http.get("http://httpbin.org/ip", nil, function(code, data)
    if (code < 0) then
      print("HTTP request failed")
    else
      print(code, data)
    end
  end)
  -- coe above


end

function metingNaarThingSpeak()  
  local a = adc.read(0)
  print("Value of moisture sensor: "..a)
  local conn = nil
  conn = net.createConnection(net.TCP, 0)
  conn:on("receive", function(conn, payload) end)
  conn:connect(80, "api.thingspeak.com")
  conn:on("connection", function(conn, payload)
  conn:send("GET /update?api_key=API_KEY&field1="..a.." HTTP/1.1\r\nHost: api.thingspeak.com\r\nConnection: keep-alive\r\nAccept: */*\r\n\r\n") end)
  conn:close()
  print("Meting naar ThingSpeak verzonden")
end

gpio.trig(pirsensorpen, "up", beweging)
tmr.alarm(4, 60000, tmr.ALARM_AUTO, function() metingNaarThingSpeak() end)

期望的输出

Failed entity=/data/192a7f47-84c1-445e-a615-ff82d92e2eaa/cdata/data_0;version=2181 some lorem ipsum text.

尝试

/data/192a7f47-84c1-445e-a615-ff82d92e2eaa/cdata/data_0;version=2181

我想从error.message.match(/\/data(^\s*)/)中提取到/data/...

之后的空格

请指教。

Answer 1

您需要将否定（^）置于字符组（[..]）中：

/\/data([^\s]*)/

然而，这是一种提取网址的相当不安全的方法：有可能在真实网址之前和之后写入单词/data。您应该考虑进行更加安全的测试。

Answer 2

试试这个：

/^\/data+[-\/;\w=]+/g

匹配任何角色直到空间
