Question

我正在尝试将一个HTTP请求从.NET Core 3.1 REST API发送到另一个API，但出现以下异常。尽管我已经添加了身份验证密钥：

请求缺少身份验证密钥。请参阅"；认证">

这是我的代码：

public class AppService
{

private readonly IHttpClientFactory _clientFactory;
string key = "key=llllll ......";
string webAPIKey = "......";
string Id = "......";
public AppService(IHttpClientFactory clientFactory) {
_clientFactory = clientFactory;

}
public async Task<string> sendBroadCastNotification()
{
Data _data = new Data();
_data.title = "test data Ttile";
_data.detail = "test data detail";
Notification _notification = new Notification();
_notification.title = "test notification Ttile";
_notification.body = "test notification body";
MyNotification NotifcationData = new MyNotification {
data=_data,
notification=_notification,
to= "/topics/all"
};
try {

var client = _clientFactory.CreateClient();

client.DefaultRequestHeaders.Add("project_id", Id );
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Authorization", key);

StringContent bodyOfRequest = new StringContent(System.Text.Json.JsonSerializer.Serialize(NotifcationData ), Encoding.UTF8, "application/json");
using var httpResponse =
await client.PostAsync("https://.......", bodyOfRequest);
var result = httpResponse.Content.ReadAsStringAsync().Result;
return result;
}
catch (Exception ex)
{
throw new System.ArgumentException(ex.Message.ToString(), "original");
}
//return null;
}

}
