注册客户端 IBM Mobile First 时出错

Question

我正在使用 IBM Mobile First Starter pack，但无法找到解决错误的方法 "Error Registering Client"。有没有办法调试这个？这从昨天开始出现在我的移动应用程序上，从今天早上开始也出现在我的模拟器上。我怀疑我的模拟器能正常工作是因为它正在缓存凭据。

Answer 1

重置模拟器或删除应用程序并重新安装。这样错误就不会再发生了：https://developer.ibm.com/answers/questions/206025/imfauthorizationrequest-error-invalid-grant/

Answer 2

canOpenURL: failed for URL:"fbauth2://" 错误表明您的 Info.plist 安全设置存在问题。首先，我会确认或将以下 LSApplicationQueriesSchemes 值添加到您的 Info.plist。

根据 Facebook 的建议outlined here

<key>LSApplicationQueriesSchemes</key>
<array>
    <string>fbapi</string>
    <string>fbapi20130214</string>
    <string>fbapi20130410</string>
    <string>fbapi20130702</string>
    <string>fbapi20131010</string>
    <string>fbapi20131219</string>    
    <string>fbapi20140410</string>
    <string>fbapi20140116</string>
    <string>fbapi20150313</string>
    <string>fbapi20150629</string>
    <string>fbauth</string>
    <string>fbauth2</string>
    <string>fb-messenger-api20140430</string>
</array>

如果这不能自行解决问题，我也会考虑在您的 Info.plist 中替换您的应用程序传输安全定义。为了进行测试，您可能需要将完整的 ATS 替换为

<key>NSAppTransportSecurity</key>
<dict>
  <key>NSAllowsArbitraryLoads</key>
      <true/>
</dict>

关于 ATS 和 iOS9 一般使用 Bluemix 的 IBM 博客文章可以找到更多信息 here and here
