json - AWS Lambda Handler extend S3event -


i have following pipeline:

a file uploaded s3, triggers lambda (let's call l1) runs , processing.

so @ moment, entry point looks this:

public response handlerequest(s3event event, context context) {   .... }

now, s3event json looks this:

        {             "records": [                 {                     "awsregion": "xxxxx",                     "eventname": "objectcreated:put",                     "eventsource": "aws:s3",                     "eventtime": "2017-09-12t09:27:59.471z",                     "eventversion": "2.0",                     "requestparameters": {                         "sourceipaddress": "xxxxxx"                     },                     "responseelements": {                         "x-amz-id-2": "xxxxxx",                         "x-amz-request-id": "xxxx"                     },                     "s3": {                         "configurationid": "xxxxxx1",                         "bucket": {                             "name": "xxxxx",                             "owneridentity": {                                 "principalid": "xxxxx"                             },                             "arn": "xxx"                         },                         "object": {                             "key": "xxx",                             "size": xxx,                             "etag": "xxxx",                             "versionid": null,                             "sequencer": "xxx",                             "urldecodedkey": "xxx"                         },                         "s3schemaversion": "1.0"                     },                     "useridentity": {                         "principalid": "xxxx"                     }                 }             ],         }

if pass json in "test" section, succeed.

now, point: wish add information json, this:

        {             "records": [                 {                     "awsregion": "xxxxx",                     "eventname": "objectcreated:put",                     "eventsource": "aws:s3",                     "eventtime": "2017-09-12t09:27:59.471z",                     "eventversion": "2.0",                     "requestparameters": {                         "sourceipaddress": "xxxxxx"                     },                     "responseelements": {                         "x-amz-id-2": "xxxxxx",                         "x-amz-request-id": "xxxx"                     },                     "s3": {                         "configurationid": "xxxxxx1",                         "bucket": {                             "name": "xxxxx",                             "owneridentity": {                                 "principalid": "xxxxx"                             },                             "arn": "xxx"                         },                         "object": {                             "key": "xxx",                             "size": xxx,                             "etag": "xxxx",                             "versionid": null,                             "sequencer": "xxx",                             "urldecodedkey": "xxx"                         },                         "s3schemaversion": "1.0"                     },                     "useridentity": {                         "principalid": "xxxx"                     }                 }             ],               "myerrormessage":                 {                 "envelopeerrors": [                     {                         "envelopeerrortrace": "stacktrace",                         "envelopeerrorpositions": 1,                         "envelopeerrorlength": 2                     },                     {                         "envelopeerrortrace": "secondtrace",                         "envelopeerrorpositions": 3,                         "envelopeerrorlength": 4                     }                 ],                 }         }

notice s3event json bit more data.

my question problem following: want have custom input works when pure s3event called. 

 public response handlerequest(mys3event event, context context) {     ....  }

however, have not been able achieve this.

i have tried custom pojo not work when upload s3 file. tried extend s3eventnotification class (from s3event extends), again no success.

is possible trying do?

what can have lambda (l1) call (asynchronously) sending new, modified event similar how recursive functions work.

just careful though. have put limit how deep want keep recursing. don't want end infinite calls. not sure if aws guards against this.

Add a dynamic header in angular 2 http provider -

i have http interceptor built via tutorial https://scotch.io/@kashyapmukkamala/using-http-interceptor-with-angular2 the problem need have dynamic header changes automatically once changes 'mode' in app. service able tell interceptor change header, or have interceptor pull header (which string)from service each request. able throwing away patch method, call http.patch('new header string') set header string. call in service controls 'mode' setting. wondering if there way interceptor pull recent value service each request or if can add method http provider via interceptor? i've tried call service in interceptor each request returns undefined. because creating new instance of service or copying value before service fired , loaded/changed data. i don't want pass header string every http provider call because defeats purpose of having interceptor, id able set once changes or have provider fetch service before makes request. tl;dr : need add autom
