Define DotNot Proxy in C#

jaykapalczynski — Thu, 06 May 2021 20:55:21 GMT

In JavaScript I am adding a proxy rule as such....

urlUtils.addProxyRule({ urlPrefix: "https://xxxx.xxxx.xxxx.gov/arcgis/rest/services/Testing/Test/FeatureServer/0", proxyUrl: "https://xxxx.xxxx.xxxx.gov/DotNet/proxy.ashx" });

But I have a .Net app that I need to call a GP Service from C# BUT I want to run it through the proxy so Credentials are not needed....

How would I modify this code to work in C# so I can use it to bypass credentials on a secured GP Service

urlUtils.addProxyRule({ urlPrefix: "https://xxxx.xxxx.xxxx.gov/arcgis/rest/services/Testing/Test/GP_TOOL/", proxyUrl: "https://xxxx.xxxx.xxxx.gov/DotNet/proxy.ashx" });

In my Web.config I have the URL referenced

<setting name="deletePoints_Dev" serializeAs="String"> <value>https://xxxx.xxxx.xxxx.gov/arcgis/rest/services/Testing/GPToolEditor/FeatureServer/0</value> </setting>

When I go to use this GP Tool I do this

public Boolean DeleteAllPointsFromTable() { try { string whereClause = "OBJECTID>-1"; string gpUrl = deletePoints_Dev; if (production) gpUrl = deletePoints_Prod; string reqString = gpUrl + "/deleteFeatures?where=" + whereClause;

BUT I am going to lok down this GP Tool URL like a Feature Service. Where in this workflow would I add the Proxy to bypass this authentication?

WHERE do I put this Proxy Rule?

HOW do I write this in C#

urlUtils.addProxyRule({ urlPrefix: "https://xxxx.xxxx.xxxx.gov/arcgis/rest/services/Testing/GPToolEditor/FeatureServer/0", proxyUrl: "https://xxxx.xxxx.xxxx.gov/DotNet/proxy.ashx" });

I got it with this....I went another route and got a Token for the service....I will simply apply that to the Service when I call it to satisfy the Credentials needed.

// GET TOKEN public String GetToken() { string result = null; try { string gpUrl = "https://xxxx.xxxx.xxxx.gov/arcgis/tokens/generateToken?username=User&password=U$er&expiration=15&f=json"; string reqString = gpUrl; HttpWebRequest req = WebRequest.Create(new Uri(reqString)) as HttpWebRequest; req.Method = "POST"; req.ContentType = "application/json"; // Encode the parameters as form data: byte[] formData = UTF8Encoding.UTF8.GetBytes(reqString); //req.contentLength = formData.Length; // Send the request: using (Stream post = req.GetRequestStream()) { post.Write(formData, 0, formData.Length); } // Pick up the response: //string result = null; using (HttpWebResponse resp = req.GetResponse() as HttpWebResponse) { StreamReader reader = new StreamReader(resp.GetResponseStream()); result = reader.ReadToEnd(); Console.WriteLine(result.ToString()); } return result; } catch (Exception ex) { Console.WriteLine(ex.Message); result = ex.Message; return result; } }
