I can add a new style application/zip with Postman into GeoServer, but I can't do it with C#-RestSharp. How can I do this? string url = "http://" + server + "/geoserver/rest/styles?name="+ StyleName; var client = new RestClient(url); var request = new RestRequest(Method.POST); string authInfo = username + ":" + password; request.AddHeader("authorization", "Basic " + Convert.ToBase64String(Encoding.ASCII.GetBytes(authInfo))); request.AddHeader("cache-control", "no-cache"); request.AddHeader("content-type", "application/zip"); request.AddHeader("authorization", "Basic YWRtaW46Z2Vvc2VydmVy"); FileStream uploadFileStream = System.IO.File.OpenRead(@"D:\aa.zip"); request.AddParameter("application /zip", uploadFileStream, ParameterType.RequestBody); IRestResponse response = client.Execute(request); --- string url = "http://..../geoserver/rest/styles?name=" + StyleName; wsn = "mystyle"; WebRequest request = WebRequest.Create(url); request.ContentType = "application/vnd.ogc.sld+xml"; request.Method = "POST"; string authInfo = username + ":" + password; request.Headers["Authorization"] = "Basic " + Convert.ToBase64String(Encoding.ASCII.GetBytes(authInfo)); request.Credentials = new NetworkCredential(username, password); byte[] buffer = Encoding.GetEncoding("UTF-8").GetBytes(wsn); Stream reqstr = request.GetRequestStream(); reqstr.Write(buffer, 0, buffer.Length); reqstr.Close();

## Learn How to Use Fetch and Create a Reusable Rest Client in JavaScript In this blog post, we’ll explore the basics of the Fetch API and how to create a reusable RestClient class to simplify your HTTP requests in web applications. Table of Contents What is Fetch? Using Fetch: Examples * GET Request * POST Request Reusable RestClient Class Using RestClient in React ### 🛰️ What is Fetch? The Fetch API is a modern JavaScript interface used to make HTTP requests to servers. It returns a Promise, which can be handled with async/await or .then() syntax. To learn more about Promises, check the MDN documentation. ### 🚀 Using Fetch: Examples ✅ GET Request fetch('https://jsonplaceholder.typicode.com/todos/1') .then(response => response.json()) .then(json => console.log(json)); Response: `{ "userId": 1, "id": 1, "title": "delectus aut autem", "completed": false }` This makes a simple GET request and parses the JSON response. ### 📤 POST Request const request = { title: 'foo', body: 'bar', userId: 1, }; fetch('https://jsonplaceholder.typicode.com/posts', { method: 'POST', body: JSON.stringify(request), headers: { 'Content-type': 'application/json; charset=UTF-8', }, }) .then(response => response.json()) .then(json => console.log(json)); For POST, PUT, and DELETE, you must explicitly define the method, headers, and body as shown above. ### 🧰 Reusable RestClient Class To avoid repeating fetch() logic throughout the app, I’ve created a reusable RestClient class. It simplifies HTTP communication and promotes consistency across requests. ✅ Features 1. Supports GET, POST, PUT, and DELETE requests. 2. Returns a standardized response object with helpful metadata. 3. Maps common HTTP error codes to friendly messages (e.g., 401 → "Unauthorized"). 4. Supports optional request cancellation using AbortController. #### ⚙️ Environment Setup This project uses Vite + React with the following environment variables: VITE_BASE_API_URL=https://jsonplaceholder.typicode.com VITE_API_VERSION=v1 # Optional #### 🧱 ApiResponse Interface interface ApiResponse<T> { success: boolean; data: T | null; message: string; error?: unknown; statusCode?: number; } This interface defines the standard structure for all responses. Whether a request succeeds or fails, you can consistently check: 1. `success`: if the request was successful 2. `data`: the returned payload 3. `message`: a user-friendly summary 4. `statusCode`and error: optional debugging info ### 🧪 Example: Testing RestClient with Abort Support Let’s see a real-world React component using the httpGetAsync() method with cancellation support via AbortController. export const RestClientTest = () => { const [controller, setController] = useState<AbortController | null>(null); useCommands( { actions: [ { label: "Send", variant: "solid", onClick: async () => { const newController = new AbortController(); setController(newController); const res = await restClient.httpGetAsync( "/posts", undefined, newController ); if (!res.success) { toast.warn(res.message); return; } console.log(res); }, }, { label: "Abort Controller", variant: "ghost", onClick: async () => { controller?.abort(); }, }, ], }, [controller] ); return <div>Rest Client Test</div>; }; #### 📷 Example Output Here’s what you’ll see in the console after a successful request: 1. Clicking "Send" starts an HTTP GET request using restClient.httpGetAsync(). ### 🧪 Simulating a Slow Request To test the cancellation feature, you can simulate slow network conditions in your browser: 1. Open DevTools → Network tab. 2. Change the throttling to "Slow 3G". 3. Click Send and then Abort Request quickly. 4. This cancels the in-progress HTTP request before the response arrives: 5. Clicking "Send" starts an HTTP GET request using restClient.httpGetAsync(). 6. Clicking "Abort Request" cancels the ongoing request using AbortController. ## 🚀 Full Source Code GitHub Repo - RestClientFetch Thank you for reading all the way through. I hope this implementation helps you write cleaner, more reusable, and easier-to-maintain code. See you in the next post! 🚀
