Traffic jaringan yang dimulai oleh Dialogflow untuk permintaan webhook
dikirim di jaringan publik.
Untuk memastikan traffic aman dan tepercaya di kedua arah,
Dialogflow secara opsional mendukung
Autentikasi TLS bersama (mTLS).
Selama TLS handshake standar Dialogflow,
server webhook Anda akan menampilkan sertifikat yang dapat divalidasi oleh Dialogflow,
baik dengan mengikuti rantai Certificate Authority
atau dengan membandingkan sertifikat ke Sertifikat CA kustom.
Dengan mengaktifkan mTLS di server webhook, server tersebut akan dapat mengautentikasi
sertifikat Google yang ditampilkan oleh Dialogflow
ke server webhook Anda untuk validasi, sehingga menyelesaikan pembentukan kepercayaan
timbal balik.
Meminta mTLS
Untuk meminta mTLS:
Siapkan server HTTPS webhook Anda untuk meminta sertifikat klien
selama TLS handshake.
Server webhook Anda harus memverifikasi sertifikat klien setelah menerimanya.
Instal rantai sertifikat untuk server webhook Anda,
yang dapat dipercaya secara timbal balik oleh klien dan server.
Aplikasi yang terhubung ke layanan Google
harus memercayai semua Certificate Authority yang tercantum oleh
Layanan Kepercayaan Google.
Anda dapat mendownload root certificate dari:
https://pki.goog/.
Contoh panggilan ke server webhook menggunakan mTLS
Contoh ini menggunakan agen yang ditampilkan di panduan memulai dengan
server webhook
yang menjalankan
openssl.
Contoh penyiapan
Agen Dialogflow CX yang menerima pesanan kemeja, dan mengirimkannya ke
webhook yang mengarah ke server web mandiri.
Kunci pribadi untuk komunikasi TLS dalam file bernama
key.pem.
Permintaan dikirim ke agen dari mesin klien. Untuk contoh ini, permintaannya adalah
"Saya ingin membeli kemeja merah besar". Permintaan ini dapat dikirim menggunakan Dialogflow Console, atau melalui panggilan API.
Output openssl s_server di mesin server.

Sertifikat Klien Kustom
Sertifikat klien kustom dapat dikonfigurasi di tingkat agen untuk digunakan oleh semua webhook. Pada saat pemanggilan webhook, sertifikat yang dikonfigurasi akan
ditampilkan selama handshake.
Kunci pribadi dan frasa sandi dikonfigurasi sebagai resource Secret Manager. Agen layanan Dialogflow harus diberi izin Secret Manager Secret Accessor ke secret.
Sertifikat klien harus ditandatangani oleh Certificate Authority agar handshake berhasil.
Praktik Terbaik
Untuk memastikan bahwa permintaan webhook dimulai dari agen Dialogflow Anda sendiri,
Anda harus memverifikasi Bearer
token identitas layanan
dari header Otorisasi permintaan. Atau, Anda dapat memverifikasi parameter sesi
yang diberikan sebelumnya oleh server autentikasi di sisi Anda.
Error
Jika validasi sertifikat klien gagal
(misalnya, server webhook tidak memercayai sertifikat klien),
TLS handshake akan gagal dan sesi akan dihentikan.
Pesan error umum:

Penjelasan
Gagal memverifikasi sertifikat klien: x509: sertifikat ditandatangani oleh otoritas yang tidak dikenal
Dialogflow mengirim sertifikat kliennya ke webhook eksternal, tetapi webhook eksternal tidak dapat memverifikasinya. Hal ini mungkin karena webhook eksternal tidak menginstal rantai CA dengan benar. Semua root CA dari Google harus tepercaya.

Prepare your webhook HTTPS server to request the client certificate during the TLS handshake.\n2. Your webhook server should verify the client certificate upon receiving it.\n3. Install a certificate chain for your webhook server, which can be mutually trusted by both client and server. Applications connecting to Google services should trust all the Certificate Authorities listed by [Google Trust Services](https://pki.goog/faq/#faq-27). You can download root certs from: \u003chttps://pki.goog/\u003e.\n\nSample call to a webhook server using mTLS\n------------------------------------------\n\nThis example uses the agent shown in the quickstart with a\n[webhook](/dialogflow/cx/docs/concept/webhook) server\nrunning\n[`openssl`](https://www.openssl.org/docs/manmaster/man1/openssl.html).\n\n1. Sample setup\n 1. A Dialogflow CX agent that takes shirt orders, and sends them to a webhook pointing to a standalone web server.\n 2. A private key for TLS communication in a file named `key.pem`.\n 3. A certificate chain signed by a [publicly-trusted\n CA (Certificate Authority)](/load-balancing/docs/ssl-certificates/self-managed-certs#use_a_publicly-trusted_ca) in a file named `fullchain.pem`.\n2. Execute the [`openssl s_server`](https://www.openssl.org/docs/manmaster/man1/openssl-s_server.html) program in the server machine. \n\n ```console\n sudo openssl s_server -key key.pem -cert fullchain.pem -accept 443 -verify 1\n ```\n3. A request is sent to the agent from a client machine. For this example, the request is \"I want to buy a large red shirt\". This request can be sent using the Dialogflow Console, or through an API call.\n4. Output of `openssl s_server` in the server machine. \n\n ```\n verify depth is 1\n Using default temp DH parameters\n ACCEPT\n depth=2 C = US, O = Google Trust Services LLC, CN = GTS Root R1\n verify return:1\n depth=1 C = US, O = Google Trust Services LLC, CN = GTS CA 1D4\n verify return:1\n depth=0 CN = *.dialogflow.com\n verify return:1\n -----BEGIN SSL SESSION PARAMETERS-----\n MII...\n -----END SSL SESSION PARAMETERS-----\n Client certificate\n -----BEGIN CERTIFICATE-----\n MII...\n -----END CERTIFICATE-----\n subject=CN = *.dialogflow.com\n\n issuer=C = US, O = Google Trust Services LLC, CN = GTS CA 1D4\n\n Shared ciphers:TLS_AES_128_GCM_SHA256:...\n Signature Algorithms: ECDSA+SHA256:...\n Shared Signature Algorithms: ECDSA+SHA256:...\n Peer signing digest: SHA256\n Peer signature type: RSA-PSS\n Supported Elliptic Groups: 0xEAEA:...\n Shared Elliptic groups: X25519:...\n CIPHER is TLS_AES_128_GCM_SHA256\n Secure Renegotiation IS NOT supported\n POST /shirts-agent-webhook HTTP/1.1\n authorization: Bearer ey...\n content-type: application/json\n Host: www.example.com\n Content-Length: 1595\n Connection: keep-alive\n Accept: */*\n User-Agent: Google-Dialogflow\n Accept-Encoding: gzip, deflate, br\n\n {\n \"detectIntentResponseId\": \"a7951ce2-2f00-4af5-a508-4c2cb45698b0\",\n \"intentInfo\": {\n \"lastMatchedIntent\": \"projects/PROJECT_ID/locations/REGION/agents/AGENT_ID/intents/0adebb70-a727-4687-b8bc-fbbc2ac0b665\",\n \"parameters\": {\n \"color\": {\n \"originalValue\": \"red\",\n \"resolvedValue\": \"red\"\n },\n \"size\": {\n \"originalValue\": \"large\",\n \"resolvedValue\": \"large\"\n }\n },\n \"displayName\": \"order.new\",\n \"confidence\": 0.9978873\n },\n \"pageInfo\": {\n \"currentPage\": \"projects/PROJECT_ID/locations/REGION/agents/AGENT_ID/flows/00000000-0000-0000-0000-000000000000/pages/06e6fc4d-c2f2-4830-ab57-7a318f20fd90\",\n \"displayName\": \"Order Confirmation\"\n },\n \"sessionInfo\": {\n \"session\": \"projects/PROJECT_ID/locations/REGION/agents/AGENT_ID/sessions/session-test-001\",\n \"parameters\": {\n \"color\": \"red\",\n \"size\": \"large\"\n }\n },\n \"fulfillmentInfo\": {\n \"tag\": \"confirm\"\n },\n \"messages\": [{\n \"text\": {\n \"text\": [\"Ok, let\\u0027s start a new order.\"],\n \"redactedText\": [\"Ok, let\\u0027s start a new order.\"]\n },\n \"responseType\": \"ENTRY_PROMPT\",\n \"source\": \"VIRTUAL_AGENT\"\n }, {\n \"text\": {\n \"text\": [\"You have selected a large, red shirt.\"],\n \"redactedText\": [\"You have selected a large, red shirt.\"]\n },\n \"responseType\": \"HANDLER_PROMPT\",\n \"source\": \"VIRTUAL_AGENT\"\n }],\n \"text\": \"I want to buy a large red shirt\",\n \"languageCode\": \"en\"\n }ERROR\n shutting down SSL\n CONNECTION CLOSED\n \n ```\n\nCustom Client Certificate\n-------------------------\n\nCustom client certificates can be configured at an agent level to be used by all\nwebhooks.

Alternatively, you can verify a session\nparameter provided previously by an authentication server on your side.\n\nErrors\n------\n\nIf the client certificate validation fails\n(for example, the webhook server does not trust the client certificate),\nthe TLS handshake fails and the session terminates.\n\nCommon error messages:"]]
