使用REST API检索所有应用程序列表时获取错误502 [英] Getting error 502 when using REST API to retrieves list of all applications

问题描述

  GET / imfpush / v1 / apps HTTP / 1.1 
主持人：mobilefoundation-3b-mf-server.mybluemix.net 
授权：Bearer eyJhbGciOiJSUzI1NiIsImp ... 。
内容类型：application / json 
  

另一种类型的调用

  curl -X GET -H授权：Bearer eyJhbGciOiJSUzI1N ....https：//mobilefoundation-3b-mf-server.mybluemix。 net / imfpush / v1 / apps
  

错误502：无法发出令牌请求，原因：请求失败到授权服务器，服务器响应状态代码：400和正文：{" errorCode"：" invalid_client"}，检查授权网址：

2. 使用/ imfpush服务，如下所述。


3. 使用mfpadmin服务，如下所述。

在我的示例中我将使用Postman。

1. 在 MobileFirst Operations Console>运行时设置>机密客户：

   
   
   
   
   
   • 添加（只是一个示例，选择您自己的）新的用户客户端（id：用户，秘密：用户）
   
   
   • 添加了 apps.read 和 push.application。* 范围
   
   



2. 通过向 http：// local发出POST请求来获取访问令牌主持人：9080 / mfp / api / az / v1 / token with：

   
   
   

   授权标签：

   
   
   
   
   
   • 类型：基本身份验证
   
   
   • 用户：用户
   
   
   • 密码：用户
   
   
   
   
   

   正文标签：

   
   
   
   
   
   • x-www-form-urlencoded
   
   
   • grant_code：client_credentials
   
   
   • 范围：apps.read push.application。*
   
   



3. 通过向 http：// localhost：9080 / imfpush / v1 / apps 发出GET请求获取应用程序列表：

   
   
   

   标题标签：

   
   
   
   
   
   • 授权：持票人 - access-token-from-step-2
   
   



4. 要按平台过滤列表， URL应更改为以下内容，例如

   
   
   

   ---

   
   
   

   仅获取所有应用程序的列表，使用 mfpadmin 服务应用程序端点会更快。使用Postman：

   
   

   1. 创建一个新的GET请求到 http：// localhost：9080 / mfpadmin / management-apis / 2.0 / runtimes / mfp / applications

      
      
      

      您可以将域名更改为您的域名。

   
   

   2. 在授权标签中，我设置了以下内容：

      
      
      
      
      
      • 类型：Basic Auth
      
      
      • 用户名和密码：您的用户名和密码（到控制台）
      
      
   
   

   作为回报，我收到了一份已注册的申请表。

   
   
   
   
   

   GET /imfpush/v1/apps HTTP/1.1
   Host: mobilefoundation-3b-mf-server.mybluemix.net
   Authorization: Bearer eyJhbGciOiJSUzI1NiIsImp....
   Content-Type: application/json
   

   another type of invocation

   curl -X GET -H "Authorization: Bearer eyJhbGciOiJSUzI1N...." "https://mobilefoundation-3b-mf-server.mybluemix.net/imfpush/v1/apps"
   

   Error 502: Failed to make token request, reason: Unsuccessful request to Authorization Server, server responded with status code: 400 and body : {"errorCode":"invalid_client"}, check the Authorization URL: http://localhost:8080/mfp/api/az/v1/token

   解决方案

   TL;DR: right now looks like there is a bug in the /imfpush/v1/apps endpoint where it does not filter the applications by the vendor (APNS, GCM, WNS), so you can only get a list of all applications instead...

   ---

   Note however that it all depends on your end goal. You can accomplish this by code or by using tools such as curl or Postman, Swagger etc... it all depends on what you want to achieve.

   Here are 3 ways:

   1. In the local development server - not available in Mobile Foundation service on Bluemix, you can use this URL to see the REST endpoints exposed in Swagger. You can then view push-enabled applications with this one: http://localhost:9080/doc/?url=/imfpush/v1/swagger.json#!/Applications/getAllApplications

      • First, in MobileFirst Operations Console > Runtime Settings > Confidential clients:
      • Add (just an example, choose your own) a new user client (id: user, secret: user)
      • Add the apps.read and push.application.* scopes

      Be sure to click on the knob and add the apps.read and push.applications.* scopes.

      You will also be asked to authorize. Use the username and password for the user confidential client that you previously created.

   2. Using the /imfpush service, as described below.
   3. Using the mfpadmin service, as described below.

   In my examples I will use Postman.

   1. In MobileFirst Operations Console > Runtime Settings > Confidential clients:

      • Added (just an example, choose your own) a new user client (id: user, secret: user)
      • Added the apps.read and push.application.* scopes

   2. Obtained an access token by making a POST request to http://localhost:9080/mfp/api/az/v1/token with:

      Authorization tab:

      • Type: Basic Auth
      • user: user
      • password: user

      Body tab:

      • x-www—form-urlencoded
      • grant_code: client_credentials
      • scope: apps.read push.application.*

   3. Obtained the list of applications by making a GET request to http://localhost:9080/imfpush/v1/apps with:

      Headers tab:

      • Authorization: Bearer the-access-token-from-step-2

   4. To filter the list by platform, the URL should change to the following, like the example in the API documentation: http://localhost:9080/imfpush/v1/apps/?expand=true&filter=platform==A&offset=0&size=10 But since this does not work right now... use: http://localhost:9080/imfpush/v1/apps/

   Of course, you need to change localhost to your server's host.

   ---

   To only obtain a list of all applications, it'd be faster to use the mfpadmin service applications endpoint. Using Postman:

   1. Created a new GET request to http://localhost:9080/mfpadmin/management-apis/2.0/runtimes/mfp/applications

      You can change the domain to yours.

   2. In the Authorization tab, I have set the following:

      • Type: Basic Auth
      • Username and Password: your username and password (to the console)

   In return I have received a list of registered applications.
