我正在尝试对域进行异步调用。如果我使用json响应指定有效地址,则以下代码可以正常工作,但是当地址无效时,我希望能够捕获任何可能的异常。
如何捕获返回的异常?
这是stacktrace的摘录:
消息:无效的JSON字符串
...
http.AsyncHTTPBuilder - 从响应委托抛出的异常: groovyx.net.http.HTTPBuilder$RequestConfigDelegate@420db81e
这里是代码:
def http = new AsyncHTTPBuilder( poolSize : 1,
contentType : ContentType.JSON )
def futureResult
futureResult = http.request( "http://www.notexistingdomainxyzwq.com/",
Method.GET,
ContentType.JSON ) {
response.success = { resp, json ->
log.info("SUCCESS")
}
response.failure = { resp, json ->
log.info("ERROR")
}
}
log.info("Call started");
try {
while (!futureResult.done) {
log.info('waiting...')
log.info("DONE: ${futureResult.done}")
Thread.sleep(1000)
}
} catch(ex) {
log.error("EXCE ${ex}")
}
log.info("Call completed")
答案 0 :(得分:0)
如果你调用futureResult.get()
来阻止并等待结果,这将抛出你可以捕获的异常:
try {
def result = futureResult.get()
log.info( "Done: $result" )
} catch(ex) {
log.error("EXCE ${ex}")
}
