C＃Web API如何将URL作为参数传递

Question

我有一个ac＃Web API，如下所示：

[HttpGet]
[Route("gatewayinfo/{endpointAddress}")]
public GatewayModel GetGatewayInfo(string endpointAddress)

当我调用该api时，我需要传递一个URL作为地址（ http：//example.con ）

我该如何使用HttpClient？ 如果我将url放入参数中将无法正常工作：

var client = new HttpClient();
client.SetBearerToken(token);
var result = await client.GetStringAsync(_webApiAddress + parameter);

Answer 1

您将需要对param进行编码

using (var client = new HttpClient())
{
    client.BaseAddress = new Uri(_webapiAddress);
    client.SetBearerToken(token)

    var result  = await client.GetStringAsync($"gatewayinfo/{HttpUtility.UrlEncode(parameter)}");
}
