HTTP状态代码200-299或400 [英] HTTP Status Code 200-299 or 400

问题描述

我将任务添加到任务队列中。但是，当任务运行时，出现以下错误：

进程已终止，因为它无法响应具有HTTP状态的启动请求

Java代码：

 字符串url =/myapp/showDetails.htm?userEmail=\"+userEmail; 
队列队列= QueueFactory.getDefaultQueue（）; 
 TaskOptions objTskOptions = TaskOptions.Builder.withUrl（url）
 .header（Host，BackendServiceFactory.getBackendService（）
 .getBackendAddress（BackendName））。method（Method.GET） 
 .retryOptions（RetryOptions.Builder.withTaskRetryLimit（5）.maxDoublings（3））; 
 queue.add（objTskOptions）; 
 logger.info（Task Queue URL ::+ objTskOptions.getUrl（））; 
  

为什么会收到此错误讯息？

Task Queue异步运行代码，并且结果对用户不可见。看来你的url /myapp/showDetails.htm 正在生成html？

还要确保你可以真正地手动调用完整的URL（在您的后端实例上执行）：例如 shareduserlevelcontacts.yourapp.appspot.com/myapp/showDetails.htm?userEmail=some@email

I am adding my tasks to the Task Queue. But when the tasks run, I get the following error:

"Process terminated because it failed to respond to the start request with an HTTP status code of 200-299 or 404."

Java Code:

String url = "/myapp/showDetails.htm?userEmail="+userEmail;
                Queue queue = QueueFactory.getDefaultQueue();
                TaskOptions objTskOptions = TaskOptions.Builder.withUrl(url)
                                            .header("Host",BackendServiceFactory.getBackendService()
                                            .getBackendAddress("BackendName")).method(Method.GET)
                                            .retryOptions(RetryOptions.Builder.withTaskRetryLimit(5).maxDoublings(3));
                queue.add(objTskOptions);
                logger.info("Task Queue URL::"+objTskOptions.getUrl());

Why am I getting this error message?

解决方案

The Task Queue runs code asynchronously and it's result is not visible to the user. It seems that your url /myapp/showDetails.htm is producing html?

Also make sure that you can actually invoke the full url by hand (executing on your backend instance): e.g. shareduserlevelcontacts.yourapp.appspot.com/myapp/showDetails.htm?userEmail=some@email
