native-messaging's Issues

Send messages with accented characters

Hi, vakho10. i am trying to send messages with accented characters like "á", "ç", "ô", etc, but it does not work. On the console of the chrome extention appear the following error:

(BLESSED_EXTENSION context for knldjmfmopnpolahpmmgbagdohdnhkik) undefined:1: Uncaught SyntaxError: Unexpected end of JSON input{SyntaxError: Unexpected end of JSON input
at Object.parse ()
at dispatchOnMessage (extensions::messaging:338:21)}

Do you have any idea of what could be the problem?

Messages without accented characters work fine.

How to make app work

Hi, I'm fairly new to programming but I'm interested to see how this native messaging program works. I've opened the project in an IDE but some parts of the Java code don't really make sense.

I can't read message from start.cmd

use readMessage i got nothing.
check args i got --parent-widnow=xxxx,chrome-extentions://xxxxx

start.cmd like this

java -Xdebug -Xrunjdwp:transport=dt_socket,address=9998,server=y,suspend=n -jar "%~dp0/extentions-0.0.1-SNAPSHOT-jar-with-dependencies.jar" %*

the message send from page is "{"AuthKey":"niuniu","Pensize":2,"DrawType":0,"TrackColor":255,"EditBorderColor":16711680,"Transparent":240,"SetSaveName":"aaaa","SetMagnifierLogoText":"bbbb","SetWatermarkPictureType":3,"SetWatermarkPicturePath":"","SetWatermarkTextType":1,"MosaicType":1,"DefaultPath":"1.jpg","HideCurrentWindow":0,"AutoCaptureFlag":0,"x":0,"y":0,"Width":0,"Height":0}"

do you know what's the problem ?

in chrome_debug.log i found

[2132:2840:0518/105851:ERROR:native_message_process_host.cc(292)] Native Messaging host tried sending a message that is 1953720652 bytes long.

it's seem like chrome problem ? but i search from stackoverflow,there say it's java problem. sadness.
