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：

在此处输入图像描述

使用关联的 mta.yaml：

ID: mta_ztransport_appointment
_schema-version: '2.1'

  deploy_mode: html5-repo

      build-result: dist

    path: flp
    parameters:

      buildpack: 'https://github.com/cloudfoundry/nodejs-buildpack/releases/download/v1.6.39/nodejs-buildpack-cflinuxfs3-v1.6.39.zip'
    requires:

      - 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

    parameters:

      service: destination
    type: org.cloudfoundry.managed-service

    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

您提到的博客在 approuter 中创建了一个特定的路由，/getuserinfo这样当您部署 approuter 并转到https://<app_router_domain_from_SCP>.hana.ondemand.com/getuserinfo它时，它会解码您从登录中获得的 JWT 令牌并返回详细信息。

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模型一样绑定到新模型。

希望这可以帮助！
