报文怎么计算的，一直没算出来

51951443

在用W5500时，http协议有报文，怎么计算报文
比如：

[mw_shl_code=c,true] client.println("*"); client.println("Content-Length: 123"); client.println("Content-Type: application/x-www-form-urlencoded"); client.println("Connection: close"); client.println(); client.print("{ \"deviceNo\":\"AE3ROQ38L565A3OF\","); client.print(" \"sensorDatas\":[{"); client.print(" \"sensorsId\":7799,"); client.print("\"value\":\"45.63\""); client.println("}]}"); client.println(); Serial.println("print get done."); [/mw_shl_code]

这里面是123，但怎么计算也不是123啊


上面的删减过后就是这样的

[mw_shl_code=c,true]Content-Length: 123 Content-Type:application/x-www-fo rm-urlencoded Connection:close {"deviceNo":"AE3ROQ38L565A3OF","sensorDatas":[{"sensorsId":7799,"value":"45.63"}]}[/mw_shl_code]

正点原子
