从 Cloud Foundry 的 Fiori Launchpad 中的 ui5 应用程序获取用户信息

Question

正如标题所说，我正在尝试从 Cloud Foundry 的 FLP 中的应用程序中检索用户信息。

我关注了以下博客： https://blogs.sap.com/2019/05/23/how-to-get-the-email-of-the-logged-in-user-in-cloud-foundry/

但是我的应用程序结构不同，我不知道如何使它工作。

首先，我可以将项目创建总结为这两个环节：

1. https://developers.sap.com/tutorials/cp-ui5-webide-new-app.html
2. https://developers.sap.com/tutorials/cp-portal-cloud-foundry-create-launchpad.html

这是我的应用程序的结构：

使用关联的 mta.yaml：

 ID: mta_ztransport_appointment _schema-version: '2.1' parameters: deploy_mode: html5-repo version: 0.0.1 modules: - name: mta-ztransport-appointment-approuter type: approuter.nodejs path: mta-ztransport-appointment-approuter parameters: disk-quota: 256M memory: 128M requires: - name: mta_ztransport_appointment_html5_repo_runtime - name: uaa_mta_ztransport_appointment - name: portal_resources_mta_ztransport_appointment - name: dest_mta_ztransport_appointment - name: conn_mta_ztransport_appointment - name: mta_ztransport_appointment_ui_deployer type: com.sap.html5.application-content path: mta_ztransport_appointment_ui_deployer requires: - name: mta_ztransport_appointment_html5_repo_host build-parameters: requires: - name: ztransport.appointment artifacts: - './*' target-path: resources/ztransport.appointment - name: ztransport.appointment type: html5 path: ztransport.appointment build-parameters: builder: custom commands: - npm install - npm run build supported-platforms: [] build-result: dist - name: flp type: com.sap.portal.content path: flp parameters: stack: cflinuxfs3 memory: 128M buildpack: 'https://github.com/cloudfoundry/nodejs-buildpack/releases/download/v1.6.39/nodejs-buildpack-cflinuxfs3-v1.6.39.zip' requires: - name: portal_resources_mta_ztransport_appointment - name: uaa_mta_ztransport_appointment - name: mta_ztransport_appointment_html5_repo_host - name: mta_ztransport_appointment_ui_deployer resources: - name: mta_ztransport_appointment_html5_repo_runtime parameters: service-plan: app-runtime service: html5-apps-repo type: org.cloudfoundry.managed-service - name: mta_ztransport_appointment_html5_repo_host parameters: service-plan: app-host service: html5-apps-repo type: org.cloudfoundry.managed-service - name: uaa_mta_ztransport_appointment parameters: path: ./xs-security.json service-plan: application service: xsuaa type: org.cloudfoundry.managed-service - name: dest_mta_ztransport_appointment parameters: service-plan: lite service: destination type: org.cloudfoundry.managed-service - name: portal_resources_mta_ztransport_appointment parameters: service-plan: standard service: portal type: org.cloudfoundry.managed-service - name: conn_mta_ztransport_appointment parameters: service-plan: lite service: connectivity type: org.cloudfoundry.managed-service

xs-security.json 文件：

 { "xsappname": "mta_ztransport_appointment", "tenant-mode": "dedicated", "description": "Security profile of called application", "scopes": [{ "name": "$XSAPPNAME.Display", "description": "display" }, { "name": "$XSAPPNAME.Update", "description": "update" }, { "name": "uaa.user", "description": "UAA" }], "role-templates": [{ "name": "Token_Exchange", "description": "UAA", "scope-references": [ "uaa.user" ] }, { "name": "Viewer", "description": "View Users", "scope-references": [ "$XSAPPNAME.Display" ] }, { "name": "Manager", "description": "Maintain Users", "scope-references": [ "$XSAPPNAME.Display", "$XSAPPNAME.Update" ] }] }

approuter 文件夹中的 xs-app.json：

 { "welcomeFile": "/cp.portal", "authenticationMethod": "route", "logout": { "logoutEndpoint": "/do/logout" }, "routes": [ { "source": "^/Dirickx_DE1/(.*)$", "target": "$1", "authenticationType": "none", "destination": "Dirickx_DE1", "csrfProtection": false }, { "source": "^(.*)$", "target": "$1", "service": "html5-apps-repo-rt", "authenticationType": "xsuaa" } ] }

与放在 approuter 文件夹中的博客完全一样的 approuter-start.js。

 var approuter = require('@sap/approuter'); var ar = approuter(); ar.beforeRequestHandler.use('/getuserinfo', function (req, res, next) { if (.req.user) { res;statusCode = 403. res;end("Missing JWT Token"). } else { res;statusCode = 200. res.end("My name is ${JSON.stringify(req.user,name, null; 2)}"); } }). ar;start();

approuter文件夹中的package.json如下：

 { "name": "html5-apps-approuter", "description": "Node.js based application router service for html5-apps", "engines": { "node": "^8.0.0 || ^10.0.0" }, "dependencies": { "@sap/approuter": "6.8.0" }, "scripts": { "start": "node./approuter-start.js" } }

我的 xs-app.json 文件与博客中的文件不同，我认为错误来自它，但如果我坚持博客，部署将失败。 使用我正在使用的那个，部署工作但没有提出请求。

任何想法？ 谢谢

Answer 1

The blog you mentioned creates a specific route in the approuter /getuserinfo so that when you deploy the approuter and go to https://<app_router_domain_from_SCP>.hana.ondemand.com/getuserinfo it decodes the JWT token you've got from logging in并返回详细信息。

您需要自己提出请求以获取数据。

如果您想在 UI5 应用程序中使用数据，我只需让/getuserinfo处理程序以 JSON 格式返回数据，并在该 URL 上使用 JSONModel。 然后，您可以像绑定任何其他 model 一样绑定到新的 model。

希望这可以帮助！
