向标头添加授权

本文关键字:授权 添加 | 更新日期: 2023-09-27 18:33:08

我有以下代码:

...
AuthenticationHeaderValue authHeaders = new AuthenticationHeaderValue("OAuth2", Contract.AccessToken);
string result = await PostRequest.AuthenticatedGetData(fullUrl, null, authHeaders);
return result; 
...
public static async Task<string> AuthenticatedGetData(string url, FormUrlEncodedContent data, AuthenticationHeaderValue authValue)
{
    HttpClient client = new HttpClient();
    client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue(authValue.Parameter);
    HttpResponseMessage response = await client.PostAsync(new Uri(url), data);
    response.Content.Headers.ContentType = new MediaTypeHeaderValue("application/json");
    response.EnsureSuccessStatusCode();
    string responseBody = await response.Content.ReadAsStringAsync();
    return responseBody;
}

响应 = 等待部分只是继续一个持续的循环,什么也没发生。知道我做错了什么吗?

真正的问题是,我如何发送以下标头:

Authorization: OAuth2 ACCESS_TOKEN

到外部网络 API

向标头添加授权

我为此苦苦挣扎。我一直收到一条错误消息,说"格式无效",因为我有一个自定义实现,并且授权标头已根据某些标准进行验证。但是,以这种方式添加标头是有效的:

var http = new HttpClient();
http.DefaultRequestHeaders.TryAddWithoutValidation("Authorization", "key=XXX");

此行

client.DefaultRequestHeaders.Authorization = 
           new AuthenticationHeaderValue(authValue.Parameter);

将生成此标头值

Authorization: ACCESS_TOKEN

其中ACCESS_TOKENauthValue.Parameter的值。您希望分配传递的值以获取所需的标头

client.DefaultRequestHeaders.Authorization = authValue;

将产生

Authorization: OAuth2 ACCESS_TOKEN

在让 AuthenticationHeaderValue 处理我的请求时遇到了类似的问题。我还使用了GitHub上的JWT JsonWebToken。我能够从 API 获得令牌,但很难在其他 GAT 和 POST 中使用它。

var jwt = JsonWebToken.Encode(token, APISECRET, JwtHashAlgorithm.HS256);
var tk = GetTokenFromApi(); // basically returns an encrypted string.

手动使用网络请求:哪个工作正常。

request.ContentType = "application/json";
request.Method = "POST";
request.Headers.Set("Authorization", string.Format("Bearer {0}", tk));

当我们切换到 HttpClient 并使用 AuthenticationHeaderValue 时,无法弄清楚如何正确设置它。查看请求字符串后,我看到它为我添加了"授权"。玩弄了参数,这终于奏效了。

 var authenticationHeaderValue = new AuthenticationHeaderValue("Bearer", tk);

在代码中,您正在执行以下操作:

client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", $"{token}");

我认为以下内容应该以相同的方式工作,而无需使用字符串插值:

client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", token);

这是因为字符串插值只是生成一个包含令牌的字符串!

也许是为了其他人而感到不安。因为我搜索了很长时间。但是您还必须保存您的 cookie 并在您的下一个请求中提供它。首先,这就是我获取身份验证代码并将 cookie 保存在静态变量中的方式(在我第一次调用此方法时,我给令牌一个空值)。

    public static CookieContainer CookieContainer;
    public static async Task<string> Post<TRequest>( TRequest requestBody, string path, string token = "")
    {
        var baseUrl = new Uri($"urlFromApi");
        CookieContainer = new CookieContainer();
        using (var handler = new HttpClientHandler() { CookieContainer = CookieContainer })
            using(var client = new HttpClient(handler){BaseAddress = baseUrl})
        {
            client.DefaultRequestHeaders.ConnectionClose = false;
            if (!string.IsNullOrWhiteSpace(token))
            {
                client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", $"{token}");
            }
            ServicePointManager.FindServicePoint(client.BaseAddress).ConnectionLeaseTimeout = 60 * 1000; //1 minute            using (var content = new ByteArrayContent(GetByteData(requestBody)))
            using (var content = new ByteArrayContent(GetByteData(requestBody)))
            {
                content.Headers.ContentType = new MediaTypeHeaderValue("application/json");
                var response = await client.PostAsync(String.Empty, content);
                return await GetResponseContent(response);
            }
        }
    }

在此之后,如果我对 api 发出任何请求,我会包含 cookie(令牌是您从第一个响应中获得的结果) 公共静态异步任务获取(字符串路径,字符串令牌 = ") {

        var baseUrl = $"https://innoviris-ai.collibra.com/rest/2.0{path}";
        using (var handler = new HttpClientHandler() { CookieContainer = CookieContainer })
        using (var client = new HttpClient(handler) {BaseAddress = new Uri(baseUrl)})
        {
            client.DefaultRequestHeaders.ConnectionClose = false;
            if (!string.IsNullOrWhiteSpace(token))
            {
                client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", $"{token}");
            }
            ServicePointManager.FindServicePoint(client.BaseAddress).ConnectionLeaseTimeout = 60 * 1000; //1 minute     
            var response = await client.GetAsync(String.Empty);
            return await GetResponseContent(response);
        }
    }
