Question

我在Phantomjs（无头浏览器）的帮助下使用Eclipse进行爬行来创建和调用AWS Lambda函数进行爬网。在执行Lambda函数时，它会抛出非法状态异常错误。可执行文件位于 / var / task / phantomjs 。我甚至尝试对该可执行文件应用 chmod 命令，但仍显示相同的错误。代码如下

Runtime r = Runtime.getRuntime();
try {
    Process p = r.exec("chmod 755 /var/task/phantomjs");
} catch (IOException e1) {
    e1.printStackTrace();
}

DesiredCapabilities dCaps = new DesiredCapabilities();
dCaps.setJavascriptEnabled(true);
dCaps.setCapability("takesScreenshot", false);      

dCaps.setCapability(PhantomJSDriverService.PHANTOMJS_EXECUTABLE_PATH_PROPERTY,"/var/task/phantomjs");
WebDriver driver = new PhantomJSDriver(dCaps);

错误如下：

The driver is not executable: /var/task/phantomjs: java.lang.IllegalStateException

如果你能提前解决这个问题，那将会非常有帮助，谢谢你。
