【中文标题】注册客户 IBM Mobile First 时出错

【英文标题】：Error Registering Client IBM Mobile First

【发布时间】：2015-11-27 02:55:20

【问题描述】：

我正在使用 IBM Mobile First Starter 包，但无法找到如何解决错误“注册客户端错误”。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，从今天早上开始出现在我的模拟器上。我怀疑我的模拟器工作正常，因为它正在缓存凭据。

【参考方案1】：

canOpenURL: failed for URL:"fbauth2://" 错误表明您的 Info.plist 安全设置存在问题。首先，我将确认或将以下 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，我还会考虑替换 Info.plist 中的应用程序传输安全定义。为了测试，您可能想用

替换完整的 ATS

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

在 IBM 博客文章中有更多关于 ATS 和 ios9 在一般情况下使用 Bluemix 的信息，可以找到 here 和 here

【参考方案2】：

重置模拟器或删除应用并重新安装。该错误不应再次发生：https://developer.ibm.com/answers/questions/206025/imfauthorizationrequest-error-invalid-grant/

【讨论】：

我试过重置模拟器并重新安装应用程序。 2015-11-27 15:15:46.708 bluelist-objective-c[4406:115870]-canOpenURL：URL 失败：“fbauth2://”-错误：“（null）”2015-11-27 15:16： 17.162 bluelist-objective-c[4406:115870] [ERROR] [IMF_REQUEST] -[IMFAuthorizationRequest requestFailed:error:] in IMFAuthorizationRequest.m:368 :: Status code='400' error='预期的状态码在（200-299 )，得到 400' response='"error":"unauthorized_client","error_description":"Unknown client"'
