Я нашел решение этой проблемы. Он работает для моего Selenium GRID с удаленными браузерами Chrome. Первым делом я стал хранить распакованное расширение ModHeader(версия 1.2.4) в ресурсах своего проекта. это выглядит так
Если мне нужно изменить заголовок в Chrome, я делаю следующие шаги:
1) распаковать папку с расширением из ресурсов во временную папку
2) установить ключи и значения заголовка в header.json
3) запаковать это расширение в zip-файл с помощью Java
4) добавить zip-файл в ChromeOptions
public static IDriver getDriverWithCustomHeader(List<HeaderElement> headerList) {
Logger.info(StringUtils.buildString("Create new instance of Driver with header."));
IDriver driver;
DesiredCapabilities capabilities;
switch (GlobalConfig.getInstance().getDriverType()) {
case CHROME:
// define path to resources
String unpackedExtensionPath = FileUtils.getResourcePath("chrome_extension", true);
// setting headers for extension in unpackaged kind
FileUtils.writeToJson(StringUtils.buildString(unpackedExtensionPath, File.separator, "header.json"), headerList);
// packing prepared extension to ZIP with crx extension
String crxExtensionPath = ZipUtils.packZipWithNameOfFolder(unpackedExtensionPath, "crx");
// creating capability based on packed extension
capabilities = CapabilityFactory.getChromeCapabilitiesWithExtension(crxExtensionPath);
driver = new AppiumDriver(GlobalConfig.getInstance().getHost(), GlobalConfig.getInstance().getPort(),
capabilities);
break;
default:
throw new CommonTestRuntimeException("Unsupported Driver Type for changing head args.");
}
drivers.add(driver);
if (defaultDriver != null) {
closeDefaultDriver();

return driver;

Tools/Chrome_ModHeader_2_0_6.crxна удаленной машине. Проблема может заключаться в том, что файл недоступен на вашем удаленном компьютере и, следовательно, не может быть установлен. Локально он работает, потому что он доступен в вашей локальной системе. - person Prasanta Biswas schedule 26.02.2018
