语音服务 - 如何使用“授权：持票人”用C＃语言进行身份验证？ [英] Speech Service- How to use "Authorization: Bearer" to authenticate in C # language?

问题描述

我的应用程序与"Ocp-Apim-Subscription-Key"完美配合。在哪里我报告了关键。但是现在我通过返回错误运行它时出现问题："附加信息：远程服务器返回错误：（401）未经授权。"。


我看到它有"授权：持票人"。标题，但我不知道怎么做。



我的申请中没有改变任何内容，我只是开始犯错误。



谢谢。

My application was working perfectly with "Ocp-Apim-Subscription-Key" where I reported the key. But now I'm having problems running it by returning the error: "Additional information: The remote server returned an error: (401) Unauthorized.".

I saw that it has the "Authorization: Bearer" header, but I do not know how to do it.

I have not changed anything in my application, I just start making mistakes.

Thanks.

推荐答案

您好，

您可以使用此示例来获取令牌。 

You can use this sample to get the token. 

public class Authentication
{
    public static readonly string FetchTokenUri =
        "https://westus.api.cognitive.microsoft.com/sts/v1.0/issueToken";
    private string subscriptionKey;
    private string token;

    public Authentication(string subscriptionKey)
    {
        this.subscriptionKey = subscriptionKey;
        this.token = FetchTokenAsync(FetchTokenUri, subscriptionKey).Result;
    }

    public string GetAccessToken()
    {
        return this.token;
    }

    private async Task<string> FetchTokenAsync(string fetchUri, string subscriptionKey)
    {
        using (var client = new HttpClient())
        {
            client.DefaultRequestHeaders.Add("Ocp-Apim-Subscription-Key", subscriptionKey);
            UriBuilder uriBuilder = new UriBuilder(fetchUri);

            var result = await client.PostAsync(uriBuilder.Uri.AbsoluteUri, null);
            Console.WriteLine("Token Uri: {0}", uriBuilder.Uri.AbsoluteUri);
            return await result.Content.ReadAsStringAsync();
        }
    }
}
