amazon web services - AWS Lambda S3Event deserialization -

-

has implemented java based request handler s3 events?

my class:

package example;  import com.amazonaws.services.lambda.runtime.context; import com.amazonaws.services.lambda.runtime.requesthandler; import com.amazonaws.services.s3.model.s3event;  public class hello implements requesthandler<s3event, string> {     public string handlerequest(s3event event, context context) {         return "success";     } }

error message:

an error occurred during json parsing: java.lang.runtimeexception java.lang.runtimeexception: error occurred during json parsing caused by: java.io.uncheckedioexception: com.fasterxml.jackson.databind.jsonmappingexception: can not deserialize instance of com.amazonaws.services.s3.model.s3event out of start_object token @ [source: lambdainternal.util.nativememoryasinputstream@6108b2d7; line: 1, column: 1] caused by: com.fasterxml.jackson.databind.jsonmappingexception: can not deserialize instance of com.amazonaws.services.s3.model.s3event out of start_object token @ [source: lambdainternal.util.nativememoryasinputstream@6108b2d7; line: 1, column: 1] @ com.fasterxml.jackson.databind.jsonmappingexception.from(jsonmappingexception.java:148) @ com.fasterxml.jackson.databind.deserializationcontext.mappingexception(deserializationcontext.java:835) @ com.fasterxml.jackson.databind.deserializationcontext.mappingexception(deserializationcontext.java:831) @ com.fasterxml.jackson.databind.deser.std.enumdeserializer._deserializeother(enumdeserializer.java:137) @ com.fasterxml.jackson.databind.deser.std.enumdeserializer.deserialize(enumdeserializer.java:89) @ com.fasterxml.jackson.databind.deser.std.enumdeserializer.deserialize(enumdeserializer.java:18) @ com.fasterxml.jackson.databind.objectreader._bindandclose(objectreader.java:1441) @ com.fasterxml.jackson.databind.objectreader.readvalue(objectreader.java:1047)

the solution take s3eventnotification. wish covered in aws documentation. lambda concept there not documentation or examples out there.

public void mergeglau(s3eventnotification notification, context context) {     try {         (s3eventnotificationrecord record : notification.getrecords()) {             system.out.println(record.geteventsource());             system.out.println(record.geteventname());             system.out.println(record.gets3().getbucket().getname());             system.out.println(record.gets3().getobject().getkey());         }     }     catch (exception e) {         e.printstacktrace();     } }

asp.net mvc - breakpoint on javascript in CSHTML? -

-
i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
