C# HttpUtility.UrlEncode 與 JAVA URLEncoder.encode 區別

C# HttpUtility.UrlEncode(param_body, Encoding.) 

是"%7b%22order_no%22%3a%228781442235161190%22%2c%22status%22%3a%222000%22%7d461de5b941e9622585cc8c184f65aef6"

 

而JAVA URLEncoder.encode(param_body, "utf-8") 

%7B%22order_no%22%3A%228781442235161190%22%2C%22status%22%3A%222000%22%7D461de5b941e9622585cc8c184f65aef6

 

status並無變，只是Encoder部分產生的代碼 C#用的小寫，而JAVA用的是大寫

UrlEncode不會對「*」進行編碼，若是須要，需手動將「*」替換爲「%2A」

方式一

  private static string UrlEncode(string temp, Encoding encoding)
        {
            StringBuilder stringBuilder = new StringBuilder();
            for (int i = 0; i < temp.Length; i++)
            {
                string t = temp[i].ToString();
                string k = HttpUtility.UrlEncode(t, encoding);
                if (t == k)
                {
                    stringBuilder.Append(t);
                }
                else
                {
                    stringBuilder.Append(k.ToUpper());
                }
            }
            return stringBuilder.ToString();
        }
