Sitecore WFFM 保存到数据库失败答案

【问题标题】：Sitecore WFFM Save To Database failedSitecore WFFM 保存到数据库失败
【发布时间】：2015-04-01 11:02:28
【问题描述】：

我在 Sitecore 日志文件中收到以下错误。在 WFFM 表单中的“保存到数据库”操作中。面向营销人员的 Web 表单 2.4 修订版。 141008.

我有一个自定义 WFMDataProvider，它只返回一个连接字符串。我在生产 CD 而不是 CMS 上收到错误。（我没有使用 remoteWfmService）我错过了什么？

【问题讨论】：

您使用的密码是否包含特殊字符？我发现 WFFM 不能很好地处理这些，因为连接字符串被解析为实体框架连接字符串。如果是这样，我会尝试一个简单的密码来排除这种情况。
No 密码没有任何疯狂的特殊字符。
你的连接字符串是什么样子的？你检查过连接字符串中的元数据部分了吗？
您是否已发布所有表单并提交操作？您在remoteWfmService connectionString 中指定的用户是否对表单项具有必要的权限？还要确保 WFFM 和任何自定义保存操作 dll 已正确部署到 CD。

【解决方案1】：

我发现 MSCaptcha.dll 没有部署。通常，当此文件丢失时，您会收到异常。但在这种情况下，App_Config\include\Captcha.config 也丢失了。

如果您删除这 2 个文件，看起来一切都适用于表单（没有验证码），但保存到数据库操作不起作用，需要这个 MSCaptcha.dll。因此给出了问题中提到的错误。我几乎可以肯定这是问题所在。我只需要一个部署来确认。
