我试图运行在Google Appengine上运行的GWTP搜寻器。
https://github.com/ArcBees/GWTP/wiki/Crawler-Support
https://github.com/ArcBees/GWTP-Samples/tree/master/gwtp-samples/gwtp-sample-crawler-service
由于文档很短，所以我无法运行它。
我可以部署我的gwtp-cralwer，但是在尝试爬网应用程序时出现以下错误。
我尝试了这样的网址：
http://testcrawler.appspot.com/?key=123456&url=http://google.com
并得到以下错误

我该如何解决？
最佳答案
您需要在ArcBees GWTP-Samples Issues中提出。您的问题中没有足够的信息，Internet上的程序员无法重现该问题。如果没有其他人可以帮助您，则将搜索集中在文本FIREFOX_17的来源-它很可能应该是一个值，而不是字段名称。
