简单的 HttpRequestMessage 但不工作

Question

我正在编写一个简单的 dotnet 核心 API，在搜索控制器下，如下所示：

[HttpGet("order")]    
public async Task <Order> SearchOrder(string ordername, int siteid) {
    return await service.getorder(ordername,siteid)
}

The swagger UI where the path https://devehost/search/order test pretty work, but when I use another client to call this api by below

client = new HttpClient {
    BaseAddress = new Uri("https://devehost")
};

var request = new HttpRequestMessage(HttpMethod.Get, "Search/order")  {
    Content = new FormUrlEncodedContent(
        new List<KeyValuePair<string, string>> {
            new("ordername", "pizza-1"),
            new("siteid", "1"),
       })
};

var response = await client.SendAsync(request);

状态码总是return错误的请求。但是邮递员在工作，我能知道里面的问题吗？

谢谢

对于 GET 请求，参数应在查询字符串中发送，而不是请求正文。

GET - HTTP | MDN
Note: Sending body/payload in a GET request may cause some existing implementations to reject the request — while not prohibited by the specification, the semantics are undefined.

对于 .NET Core，您可以使用 the Microsoft.AspNetCore.WebUtilities.QueryHelpers class 将参数附加到 URL:

Dictionary<string, string> parameters = new()
{
    ["ordername"] = "pizza-1",
    ["siteid"] = "1",
};

string url = QueryHelpers.AppendQueryString("Search/order", parameters);
using var request = new HttpRequestMessage(HttpMethod.Get, url);
using var response = await client.SendAsync(request);
