electron如何调用第三方应用

electron如何调用第三方应用

主要通过node官方模块的child_process，实际操作代码如下：

1
2
const spawn = require("child_process").spawn;
const ide = spawn("\"" + path.join(arduinoPath, "/arduino") + "\"", ["\"" + filename + "\""], { shell: true });

在本次应用中，主要实现了，通过第三方Arduino软件编译并上传hex的过程。
代码如下：

            const genhex = spawn(builder, [argHardware, argTools, argcFlag, argLibraries, argFlag, argBuildPath, argFile], { shell: true });
            _mainWindow.webContents.send('uploadHex-status', 'verify');
            genhex.on("close", (exitcode) => {

                    const spawn = require("child_process").spawn;
                    const upload = spawn(app, [argConf, argCpu, argFile, argPort, argBaud, " -q"], { shell: true });
                    upload.on("close", (exitcode) => {

                    });
                } else {
                    _mainWindow.webContents.send('uploadHex-err');
                }
            });
