AWS API Gateway - How do I get the date/timestamp/epoch in a body mapping template?

由 故事扮演 提交于 2019-12-04 10:50:20
I need to include the request time in the body mapping template for an API Gateway method. Is there a date/time variable or function? I couldn't find anything in the template reference . Example body mapping template: Action=SendMessage&MessageBody=$util.urlEncode("{""timestamp"":""TIMESTAMP_HERE"",""body-json"":$input.json('$'),""params"":""$input.params()""}") UPDATE: API Gateway just added two new context variables http://docs.aws.amazon.com/apigateway/latest/developerguide/api-gateway-mapping-template-reference.html $context.requestTime The CLF-formatted request time (dd/MMM/yyyy:HH:mm:ss

IntelliJ IDEA override $user

由 痴心易碎 提交于 2019-12-03 15:01:02
It's a quite simple question, but I can't find an answer to it using SO-Search and Google. Is it possible to override the default $user VTL-variable used in file-templates globally, instead of setting it in each template with #set($user = "...") ? Like some sort of setup-script for IntelliJ itself, where I can alter the value? Thanks in advance. By the way, I'm using IntelliJ Ultimate 12.1.6.

Replace a Substring of a String in Velocity Template Language

由 巧了我就是萌 提交于 2019-12-03 10:34:20
问题 I want to replace a part of a string in Velocity Template Language with another string. For Example: #set($a = "Hello") #set($b = "+") I want to replace ll in Hello with ++. The output should be He++o Please help me Thanks Kishore 回答1: By default you can use the methods of the Java String object: #set( $a = "Hello" ) #set( $b = $a.replace("l", "+") ) ${b} will produce He++o and you can also use velocity variables as arguments to your method calls, e.g.: #set( $a = "Hello" ) #set( $b = "+" )
