Question

我遇到問題。 當我在我的網站項目（.net 4.0 aspx webform）上嘗試使用PayPal進行付款時（PayPalCoreSDK版本爲1.3.4.0，RestApiSDK版本爲0.7.3.0）我有一個問題，錯誤消息。 但有時順利運行 此消息是;

你能幫我快點嗎？ 謝謝。

Answer 1

我遇到了同樣的問題。 對我而言，事實證明，這是由交易描述中的某些字符和交易中的物品造成的。例如。 '歐元符號'，等等。

看起來像編碼這不是由庫處理（正確）。

Answer 2

1月是完全正確的，並感謝你的重要領導。

自從我上週使用新付款形式上線以來，我一直在努力解決這個偶然的錯誤。事實證明，許多國際地址包含含有變音標記的字母（http://en.wikipedia.org/wiki/Diacritic）。我通過在我的發佈數據中使用這些字符在PayPal沙箱中確認了這個問題，並且重複地得到了上面描述的確切錯誤。我也在使用上面描述的相同的庫。

爲了試圖解決這個問題（適用於所有的測試到目前爲止）我擦洗我的用戶輸入（地址1號線，2號線，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; 
    }
