本指南說明如何設定所需的伺服器基礎架構 僅用於接收及處理 EMM 推播通知。 提取通知不需要進行本指南中詳述的設定。
除了本指南所述的伺服器設定之外,您也適用推播通知 您也必須授予適當權限 執行其他設定 建立工作詳情請見 啟用 EMM 推播通知 。
如要進一步瞭解 Google Cloud Pub/Sub (包含範例),請參閱: Cloud Pub/Sub 說明文件。
您可以將系統設定為 或等待通知傳送的伺服器。
關於推送端點設定
如要設定推送端點,您需要伺服器具備有效的 SSL 憑證。於 在此範例中,您會建立 SSL 憑證並上傳到憑證授權單位 (CA),然後設定 NGINX 伺服器。最後,在 Python 中 確認您的設定正確無誤。
這個範例說明如何設定
NGINX 伺服器
反向 Proxy 模式,用來連結訂閱者應用程式 (在 PushSubscriber.java
中)
是透過 Ubuntu 14.04 來執行貴企業可能使用不同的
不過,所有以 Debian 為基礎的範例設定應可正常運作
發行。其他分佈情形 (例如以 RedHat 為基礎的模型)
但設定檔的位置可能會有所不同。
如要接收通知,您必須先設定 必須符合下列條件:
您必須在 Google API 控制台。
您必須能夠透過通訊埠 443 (SSL) 執行服務。
您必須具有 CA 簽署的 SSL 憑證。自行簽署的憑證無法運作。
您所執行的網路伺服器必須支援 Webhook。
您的端點無須在 Google App Engine 上執行 (儘管可以如此)。
建立並上傳 SSL 憑證
1. 產生安全資料傳輸層 (SSL) 憑證:
myusername@myhost:/tmp$ sudo openssl req -x509 -nodes -days 365 \ -newkey rsa:2048 -keyout cert.key -out cert.crt
這會產生下列回應。替換樣本值
(例如 push.solarmora.com
和 myusername@myhost
) 以更新實際伺服器
包括名稱、公司、地址等等您可以使用任何
子網域的 A
記錄指向您的伺服器。
Generating a 2048 bit RSA private key ........................................................................... .....+++ writing new private key to 'cert.key' ----- You are about to be asked to enter information that will be incorporated into your certificate request. What you are about to enter is what is called a Distinguished Name or a DN. There are quite a few fields but you can leave some blank For some fields there will be a default value, If you enter '.', the field will be left blank. ----- Country Name (2 letter code) [AU]:GB State or Province Name (full name) [Some-State]:England Locality Name (eg, city) []:London Organization Name (eg, company) [Internet Widgits Pty Ltd]:Solarmora, Inc. Organizational Unit Name (eg, section) []:Creative Publications Common Name (e.g. server FQDN or YOUR name) []:push.solarmora.com Email Address []:admin@solarmora.com
2. 確認憑證檔案已建立:
$ myusername@myhost:/tmp$ ls cert*
cert.crt cert.key
3. 如要取得此憑證簽署,請產生 憑證簽署要求 (CSR):
myusername@myhost:/tmp$ sudo openssl x509 -x509toreq -in cert.crt \ -out cert.csr -signkey cert.key Getting request Private Key Generating certificate request
myusername@myhost:/tmp$ ls cert.* cert.crt cert.csr cert.key
4. 確認 CSR 檔案的內容如下所示:
Certificate Request: Data: Version: 0 (0x0) Subject: C=GB, ST=England, L=London, O=Solarmora, Inc., OU=Creative Publications, CN=push.solarmora.com/emailAddress=admin@solarmora.com Subject Public Key Info: Public Key Algorithm: rsaEncryption Public-Key: (2048 bit) Modulus: 00:cc:0f:54:26:3d:d9:17:eb:8f:6c:f7:27:5e:77: 64:65:00:db:fe:2a:1f:fa:ea:de:21:7a:c5:5d:87: ... ...

5. 請在 BEGIN
之間上傳憑證的一部分
和 END
行 (含首尾)。確切程序
視您的 CA 而定,但包含下列步驟:
- 將 CSR 檔案上傳到 CA 網站,或是將檔案內容貼到 CA 網站上。接著,您的 CA 會驗證及處理這項資料。
- 下載 CA 產生的已簽署憑證。
6. CA 的輸出內容應包含多個檔案:已簽署
以及確認他們有資格使用的 CA 憑證
簽署憑證串連已下載的所有 *.crt
憑證檔案
並整合到單一套件檔案中,例如 bundle.push.solarmora.com.crt
:
$ cat *.crt > bundle.push.solarmora.com.crt
設定 Proxy 伺服器
在本節中,您將設定 NGINX 開放原始碼網路伺服器,然後反向操作 來提供端點服務,並將所有傳入要求轉送至 訂閱者伺服器。NGINX 可做為範例,但您可以使用 請改用 HTTP Proxy。
1. 在伺服器上安裝 NGINX:
$ sudo apt-get update $ sudo apt-get install nginx $ nginx -v $ nginx version: nginx/1.4.6 (Ubuntu)
2. 確保您在
sites-enabled
目錄是由 NGINX 處理,編輯 /etc/nginx/nginx.conf
並加入以下內容:
$ include /etc/nginx/conf.d/*.conf; $ include /etc/nginx/sites-enabled/*;
3. 將憑證檔案複製到安全的位置,方便
www-data
使用者,但建議不要讓其他使用者讀取 (您可能需要
以便在網路伺服器以不同的名稱執行時調整使用者名稱
使用者):
$ sudo mkdir -p /var/openssl/push.solarmora.com $ sudo mv /tmp/cert.key
/var/openssl/push.solarmora.com/push.solarmora.com.key $ sudo mv /tmp/bundle.push.solarmora.com.crt
/var/openssl/push.solarmora.com/bundle.push.solarmora.com.crt
4. 建立新的 server
設定。編輯「push.solarmora.com
」
,然後使用實際的/etc/nginx/sites-enabled
伺服器的完整網域名稱做為檔案名稱:
server {
listen 443;
server_name push.solarmora.com;
ssl on;
ssl_certificate
/var/openssl/push.solarmora.com/bundle.push.solarmora.com.crt;
ssl_certificate_key
/var/openssl/push.solarmora.com/push.solarmora.com.key;
# it is usually very convenient to have separate files for your
# access and error log to analyze for possible problems
access_log /var/log/nginx/nginx.push.solarmora.com.log;
error_log /var/log/nginx/nginx.push.solarmora.com.log;
location / {
# assuming the subscriber will run on the same machine
# on port 8093
proxy_pass http://localhost:8093;
}
}
5. 重新啟動 NGINX 以實作變更:
myusername@myhost:/etc/nginx$ sudo service nginx restart * Restarting nginx nginx ...done.
6. 伺服器現已設定完成。若要驗證
設定,請嘗試使用 curl
查詢伺服器:
[myusername@myhost:~]$ curl push.solarmora.com <html> <head><title>502 Bad Gateway</title></head> <body bgcolor="white"> <center><h1>502 Bad Gateway</h1></center> <hr><center>nginx/1.4.6 (Ubuntu)</center> </body> </html>
因為尚未設定下游伺服器,所以這是預期的回應
(設定檔中的 localhost:8093
)。
編譯並執行範例
如要執行本節中的範例,您必須擁有有效的 Google API 控制台。 專案。建議您建立專門用於測試用途的應用程式 與正式環境專案分開建立測試專案後 您必須建立服務帳戶。 記下服務帳戶的電子郵件地址,並將相關聯的 .p12 檔案放在伺服器上。
設定原始碼樹狀結構
1. 複製 play-work.git
存放區:
myusername@myhost:~/code$ git clone https://github.com/google/play-work.git Cloning into 'play-work'... Username for 'https://github.com': username Password for 'https://username@github.com': remote: Counting objects: 110, done. remote: Compressing objects: 100% (60/60), done. remote: Total 110 (delta 24), reused 95 (delta 9), pack-reused 0 Receiving objects: 100% (110/110), 23.88 KiB | 0 bytes/s, done. Resolving deltas: 100% (24/24), done. Checking connectivity... done.
$ sudo apt-get install maven protobuf-compiler
3. 確認 Maven 和 Google 通訊協定緩衝區編譯器皆已 正確安裝:
myusername@myhost:~$ mvn -v Apache Maven 3.0.5 Maven home: /usr/share/maven Java version: 1.7.0_75, vendor: Oracle Corporation Java home: /usr/lib/jvm/java-7-openjdk-amd64/jre Default locale: en_US, platform encoding: UTF-8 OS name: "linux", version: "3.16.0-30-generic", arch: "amd64", family: "unix"
myusername@myhost:~$ protoc --version libprotoc 2.5.0
4. Maven 設定檔 pom.xml
會假設通訊協定緩衝區編譯器已安裝至 /usr/bin/protoc
目錄:
myusername@myhost:~$ which protoc /usr/bin/protoc
pom.xml
或符號連結 protoc
:
$ sudo ln -s which protoc
/usr/bin/protoc
mvn clean compile assembly:single
來建構程式碼。這應該會產生一個名為
emm-notifications-[version-number]-jar-with-dependencies.jar
,其中
[version number]
是範例的最新版本,例如 1.0-SNAPSHOT
:
myusername@myhost:~/code/play-work/examples/emm-notifications$ ls target/* target/emm-notifications-1.0-SNAPSHOT-jar-with-dependencies.jar
TestPublisher
程式碼。程式碼預期會失敗:
myusername@myhost:~/code/play-work/examples/emm-notifications$ java -cp \ target/emm-notifications-1.0-SNAPSHOT-jar-with-dependencies.jar \ com.google.android.work.emmnotifications.TestPublisher Exception in thread "main" java.lang.IllegalArgumentException: You must specify non-default ServiceAccountEmail in settings.properties at com.google.api.client.repackaged.com.google.common.base.Preconditions.checkArgument(Preconditions.java:119) at com.google.api.client.util.Preconditions.checkArgument(Preconditions.java:69) at com.google.android.work.emmnotifications.Settings.verifyVariable(Settings.java:129) at com.google.android.work.emmnotifications.Settings.getSettings(Settings.java:103) at com.google.android.work.emmnotifications.TestPublisher.main(TestPublisher.java:39)
7. 您必須覆寫 settings.properties
檔案中的某些值。方法如下
建立檔案副本,並修改副本中的屬性,如下所示:
# This should be your own service account's email address ServiceAccountEmail=368628613713-t4hfexampledn5lhpdcu1qqfgio01626@developer.gserviceaccount.com ServiceAccountP12KeyFile=/opt/secret/secret.p12
# This will be the name of the service account ProjectName=enterprise-cloud-pub-sub SubscriptionName=projects/enterprise-cloud-pub-sub/subscriptions/default TopicName=projects/enterprise-cloud-pub-sub/topics/default
# The push endpoint in your API Console project PushEndpoint=https://push.solarmora.com
8. 再次執行 TestPublisher
程式碼,確保不再當機。(您可能會看到
單一錯誤)。
執行發布商測試程式碼
