paypal Rest Api错误请求被中止：请求被取消。直到写入所有字节才能关闭流

Question

我遇到问题。 当我在我的网站项目（.net 4.0 aspx webform）上尝试使用PayPal进行付款时（PayPalCoreSDK版本为1.3.4.0，RestApiSDK版本为0.7.3.0）我有一个问题，错误消息。 但有时顺利运行 此消息是;

你能帮我快点吗？ 谢谢。

Answer 1

我遇到了同样的问题。 对我而言，事实证明，这是由交易描述中的某些字符和交易中的物品造成的。例如。 '欧元符号'，等等。

看起来像编码这不是由库处理（正确）。

Answer 2

1月是完全正确的，并感谢你的重要领导。

自从我上周使用新付款形式上线以来，我一直在努力解决这个偶然的错误。事实证明，许多国际地址包含含有变音标记的字母（http://en.wikipedia.org/wiki/Diacritic）。我通过在我的发布数据中使用这些字符在PayPal沙箱中确认了这个问题，并且重复地得到了上面描述的确切错误。我也在使用上面描述的相同的库。

为了试图解决这个问题（适用于所有的测试到目前为止）我擦洗我的用户输入（地址1号线，2号线，名字，姓氏等），在下面的方法

// http://msdn.microsoft.com/en-us/library/ebza6ck1.aspx 
    String NormalizeString(String value) 
    { 
     if (!value.IsNullOrEmpty()) 
     { 
      var newStringBuilder = new StringBuilder(); 
      newStringBuilder.Append(value.Normalize(NormalizationForm.FormKD) 
              .Where(x => x < 128) 
              .ToArray()); 
      return newStringBuilder.ToString(); 
     } 

     return value; 
    }
