如何使用 HttpClientFactory 在基址末尾添加字符串值？

Question

我正在使用 HttpClientFactory 发出 http 请求。

这是我的代码：-


namespace handleDeviceOperations
{
    
class Program
{

string operationID = String.Empty;
static async Task Main(string[] args)
{
    var serviceCollection = new ServiceCollection();
    ConfigureServices(serviceCollection);
    var services = serviceCollection.BuildServiceProvider();
    var httpClientFactory = services.GetRequiredService<IHttpClientFactory>();

    //Getting operationID from few other lines of code

    var httpClientGetOperations = httpClientFactory.CreateClient("getOperations");
    var request1 = await httpClientGetOperations.GetAsync("");
    var responseMessage1 = await request1.Content.ReadAsStringAsync();
}
private static void ConfigureServices(ServiceCollection services)
{

    services.AddHttpClient("getOperations", options =>
    {
        options.BaseAddress = new Uri("https://myurl.com/events/");

        options.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic","Auth_Value");
    });   
}
}

如您所见，这是我的基址："https://myurl.com/events/" 现在，就在此处发出请求之前：-

var httpClientGetOperations = httpClientFactory.CreateClient("getOperations");
var request1 = await httpClientGetOperations.GetAsync("");

我想将 operationID 添加到 Base Address 的末尾，这样 Base Address 就变成这样：-

"https://myurl.com/events/45872254"
//The string at the end will differ each time

这是一个非常必要的步骤，因为请求完全依赖于 operationID 参数。

Answer 1

options.BaseAddress = new Uri("https://myurl.com/");
...
var id = 45872254;
var request1 = await httpClientGetOperations.GetAsync($"events/{id}");
