Question

相关：DotNetOpenAuth I Need Send Long string in FetchResponse和OpenId query length issue in DotNetOpenAuth? - 但这些都不能令人满意地回答我的问题。

我们正在使用DotNetOpenAuth将数据发布到Xero, which supports a maximum of 3MB per request。我们正尝试在requestBody中发布一个77Kb的XML字符串：

Dictionary<string, string> additionalParams = new Dictionary<string, string>();
additionalParams.Add("xml",requestBody);

var endpoint = new MessageReceivingEndpoint(requestURL, HttpDeliveryMethods.PostRequest | HttpDeliveryMethods.AuthorizationHeaderRequest);
HttpWebRequest request = XeroConsumer.PrepareAuthorizedRequest(endpoint, accessToken, additionalParams);

WebResponse response = request.GetResponse();
string thisResponse = (new StreamReader(response.GetResponseStream())).ReadToEnd();

PrepareAuthorizedRequest投掷：Invalid URI: The Uri string is too long.

有什么方法可以用DotNetOpenAuth发布“大”数据吗？

Answer 1

DotNetOpenAuth uses Uri.HexEscape() and Uri.EscapeDataString() on the additional parameters。当参数超过2Kb时，这会中断。

我已经将他们的功能换成了我自己效率低下但功能正常的功能：

    internal static string EscapeUriDataStringRfc3986(string value)
    {
        StringBuilder escaped = new StringBuilder();

        string validChars = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz-._~";

        foreach (char c in value)
        {
            if(validChars.Contains(c.ToString())){
                escaped.Append(c);
            } else {
                escaped.Append("%" + Convert.ToByte(c).ToString("x2").ToUpper());
            }
        }

        // Return the fully-RFC3986-escaped string.
        return escaped.ToString();
    }

DotNetOpenAuth消费者POST大数据; “Uri字符串太长了”
