Async / Await Examples

import SimpleNetworking

class myApiService {
    // Create a shared instance of SimpleNetworking
    let networking = SimpleNetworking.shared

    init() {
        // Set base URL (optional)
        networking.set(serverURL: "https://wesleydegroot.nl")

        // Set a custom user agent (optional)
        networking.set(userAgent: "My App")

        // Set a custom authorization header (optional)
        networking.set(authorization: "MyToken")

        // Set a custom post type (optional)
        networking.set(postType: .json) // .plain, .json, .graphQL
    }

    /// Get a user (GET request)
    func getUser() async {
        let response = await networking.request(
            path: "/api/getUser", 
            method: .get
        )

        print(response.string)
    }

    /// Update a user (POST request)
    func updateUser() async {
        let response = await networking.request(
            path: "/api/updateUser", 
            method: .post([
                "firstname": "Wesley",
                "lastname": "de Groot"
            ])
        )

        print(response.string)
    }

    /// Get all users (GET request)
    func getUsers() async {
        let response = await networking.request(
            path: "/api/getUsers", 
            method: .get
        )

        struct userProfile: Codable {
            let firstname: String
            let lastname: String
        }

        // Decode the response
        let userProfiles: [userProfile]? = networkResponse.decoded()
        print(userProfiles)
    }
}

import SimpleNetworking

/// Debug: print NSURLRequest (Default: false)
SimpleNetworking.shared.debug.requestURL = true
