WebAPI接口调用

API传输文件的接口调用方式：
using (WebClient client = new WebClient())
{
string sWFDocumentNo = lblWFDocumentNo.Text;
string ssWFApplyby = lblWFApplyBy.Text;
if (ssWFApplyby.Trim() == "")
ssWFApplyby = lblWFApplyBy.Text;
if (ssWFApplyby.Length > 5 && ssWFApplyby.ToLower().Substring(0, 4) == "gwkf")
{
ssWFApplyby = ssWFApplyby.Substring(5, ssWFApplyby.Length - 5);
}
string sValue = System.Text.Encoding.Default.GetString(fileFirstUpload.FileBytes);
string[] str = new string[] { };

string url = "";
RUC_Config rUC_Config = new RucDA().GetRUC_ConfigByWebRefName("PLAFToSAPCheck");
if (rUC_Config != null)
{
if (rUC_Config.ServerURL != null && rUC_Config.ServerURL != "")
{
url = rUC_Config.ServerURL;
}
}
var parameters = new NameValueCollection();
parameters.Add("sWFApplyby", ssWFApplyby);
parameters.Add("sWFDocumentNo", sWFDocumentNo);
parameters.Add("IfCheck", "C");
parameters.Add("Filename", fileFirstUpload.FileName);
parameters.Add("sValue", sValue);

(WFFlowID.ToString(), ItemID, System.Reflection.MethodBase.GetCurrentMethod().DeclaringType, url + "-SAP 验证开始 WFApplyby[" + ssWFApplyby + "]WFDocumentNo[" + sWFDocumentNo + "]");
var response = Encoding.UTF8.GetString(client.UploadValues(url, "Post", parameters));

if (response != "\"\"")
{
ErroMes += response;
Log4NetHelper.Fatal(WFFlowID.ToString(), ItemID, MethodBase.GetCurrentMethod().DeclaringType, "接口返回信息：" + response.ToString());
}
(WFFlowID.ToString(), ItemID, System.Reflection.MethodBase.GetCurrentMethod().DeclaringType, url + "-SAP 验证结束 WFApplyby[" + ssWFApplyby + "]WFDocumentNo[" + sWFDocumentNo + "]");
}


API接口的写法：

string sValue = form.Get("sValue");

s(sValue);
DataTable dt = dtByOpenCSV(byteArray, out sErr);
