個人的な学習のためのRepository

GOAL

  • JAX-RS(の参照実装であるJersey) をなんとなく一通り使えるようにする
  • GAE/J SE で動く

appengine-standard-java8-jax-rs-with-scala's Issues

ServletConfigからプロパティを取り出す

config.getInitParameter 関連のやつとか？
今どうせ確認だからとFirebaseAdminSDK用のjsonまでrepository管理下にあるが…
その辺を別途取り出せるようにしておきたい（し、環境別に値を切り替えたい？）

AppEngineのInstanceが一個も立ち上がっていないときにアクセスした場合のErrorの対応 

HTTP/1.1 500 Internal Server Error
X-Cloud-Trace-Context: 992e150733b9f4de5feb331a74ed7102;o=1
Date: Mon, 03 Jul 2017 14:06:48 GMT
Content-Type: text/html; charset=UTF-8
Server: Google Frontend
Content-Length: 323
Alt-Svc: quic=":443"; ma=2592000; v="39,38,37,36,35"


<html><head>
<meta http-equiv="content-type" content="text/html;charset=utf-8">
<title>500 Server Error</title>
</head>
<body text=#000000 bgcolor=#ffffff>
<h1>Error: Server Error</h1>
<h2>The server encountered an error and could not complete your request.<p>Please try again in 30 seconds.</h2>
<h2></h2>
</body></html>

これどうすれば良いんだろうな？
まさかidle instance 1にしろってことはないだろうし…（実際にこのリクエストを受けて一回立ち上がり、その後普通に動いているわけだし）

FirebaseAuthを使った簡易なサンプル

check list

  • clientはとりあえずAndroidで適当実装(暇ならFirebaseUIでも試せば？)
  • token検証でFirebase Admin SDK を使った場合、GAEをbackend serviceにしろってあるけど、そうじゃないと本当に動かない？
  • Authentication: Bearer なHeaderを ContainerRequestFilter を使って実装して動かす

reference

ExceptionMapperは全部に対応しない？

例としてError時のBodyをJsonとするようなMapperを用意している。

curl -i -X POST -d '{"c":1, "b":"hoge"}' -H 'Content-Type: application/json' https://hello-jaxrs-dot-semiotic-karma-172203.appspot.com/hello_jso 
HTTP/1.1 404 Not Found
Content-Type: application/json
X-Cloud-Trace-Context: 1b24c26d71a809feb822830a254df7b6;o=1
Date: Mon, 03 Jul 2017 14:07:08 GMT
Server: Google Frontend
Content-Length: 196
Alt-Svc: quic=":443"; ma=2592000; v="39,38,37,36,35"

{"status_code":404,"status_type":"CLIENT_ERROR","message":"Not Found","for_developer":{"message":"HTTP 404 Not Found","path":"https://hello-jaxrs-dot-semiotic-karma-172203.appspot.com/hello_jso"}}

これはわかる。想定通り。

curl -i -X POST -d '{"c":1, "b":"hoge"}' -H 'Content-Type: application/json' https://hello-jaxrs-dot-semiotic-karma-172203.appspot.com/hello_json
HTTP/1.1 400 Bad Request
Content-Type: text/plain

Content-Length: 312

Unrecognized field "c" (class com.example.sample.RequestBody), not marked as ignorable (2 known properties: "a", "b"])

なんでPlanTextなんだろうな？
