快速入门中的“立即尝试"不再返回 [英] 'Try it now' in the Quick Start never returns

问题描述

我已经在 Win 7 64 中安装了 API Mgr 1.7.0.我已经阅读了快速入门指南，一切似乎都如描述的那样工作.然而，当我开始尝试订阅的 cdyne api 时，移动的点"图形永远留在那里.除了浏览器刷新之外，我找不到阻止它的方法.我在 API Mgr 系统日志中看不到任何条目.

I have installed the API Mgr 1.7.0 in Win 7 64. I have been through the Quick Start guide and all appeared to work as described. However, when I get to the point of trying the subscribed-to cdyne api, the 'moving dots' graphic stays there forever. I can't find a way to stop it, other than a browser refresh. I can't see an entry in the API Mgr system logs.

我已经删除了应该返回 401 的参数和身份验证信息，但它没有并且移动的点继续.我使用的是带有 AdBlock+ 和 Noscript 的 Firefox 31.据我所知，没有被阻止的脚本.

I have removed the parameters and the auth info, which is supposed to return a 401, but it doesn't and the moving dots continue. I'm using Firefox 31, with AdBlock+ and Noscript. There are no blocked scripts as far as I can see.

[edit 1] 我在第一个样本 (YouTube) 上遇到了同样的问题.请问这个问题是不是端口值引起的?由于安装了 ESB，我将 API Mgr 的所有端口增加了 1.也许我错过了一个，或者还有一个没有记录.[/edit 1]

[edit 1] I get the same problem with the first sample (YouTube). I wonder if the problem is caused by port values? As I have the ESB installed, I increased all the ports for API Mgr by 1. Maybe I missed one, or there is one that hasn't been documented.[/edit 1]

[edit 2] 我重新安装了 API Mgr.我停止了 ESB 并将 APIM 端口保留为默认值.我重新创建了电话验证服务，但立即尝试"仍然存在同样的问题.我把全局日志级别设置为DEBUG，但是细节太多没用.我不知道为这个问题设置什么包名.

[edit 2] I have reinstalled the API Mgr. I stopped the ESB and left the APIM ports as default. I have recreated the Phone Verify service and I still have same problem with 'Try it now'. I set the global log level to DEBUG, but there is too much detail to be of use. I don't know what package names to set for this problem.

应用程序日志中有如下条目，可能与此相关.显示了前几行:

There was an entry in the Application Logs as follows, which might be relevant. The first few lines are shown:

发生系统错误尝试调用服务方法 getApplicationNames

推荐答案

您可能没有配置 CORS.CORS 是跨源资源共享 [1]，它被商店中的 try-it 功能使用.

You may not have configured CORS. CORS is cross-origin resource sharing [1] and it is used by the try-it feature in the store.

CORS 配置存储在 [API Manager Home]/reposotiry/conf/api-manager.xml 中.标头必须包含 CORS 请求使用的主机名.try-it 服务使用的主机名在 API-Console/try-it 屏幕的左下角显示为灰色.它应该显示为基本网址".例如:[ base url: http://10.212.0.846.:8281 , api version: 1.0 ]

The CORS configuration is stored in [API Manager Home]/reposotiry/conf/api-manager.xml . The header must include the Host name used by the CORS request. The host name being used by the try-it service is shown in gray at the bottom-left hand corner of the API-Console / try-it screen. It should show up as 'base url'. For example: [ base url: http://10.212.0.846.:8281 , api version: 1.0 ]

您也可能在使用默认 API 时遇到问题 - 请确保 [API Manager Home]/repository/deployment/server/synapse-configs/default/api/中的 API 已更新为您的端口偏移量.这可能会阻止基本身份验证.它记录在此处 [2]

You may also be having trouble with the default APIs - please make sure that the APIs in [API Manager Home]/repository/deployment/server/synapse-configs/default/api/ are updated with your port offset. This may be preventing basic authentication. It is documented here [2]
