Question

我正在尝试通过API调用访问数据。身份验证要求是：

身份验证令牌需要在标题名称ACCESS-TOKEN下作为调用中的标题传递。注意：将Content-Type添加为Application / JSON

var uri = new Uri(string.Format("https://stg-api.oyorooms.ms/api/v2/hotels/get_availability/"));
var json = JsonConvert.SerializeObject(action);
var content = new StringContent(json, Encoding.UTF8, "application/json");

HttpResponseMessage response = null;
if (isNewItem)
{
    // client.BaseAddress = new Uri("https://stg-api.oyorooms.ms/api/v2/hotels/get_availability/");
    client.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("ACCESS-TOKEN", "c19.....j5XeS0=");
    client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
    HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Post, "relativeAddress");
    request.Content = new StringContent(content.ToString(),
            Encoding.UTF8,
            "application/json");
    response = client.PostAsync(uri, content).Result;

    resp = response.Content.ToString();//for getting break points
}
var resp1 = response.Content.ToString();//for getting break points

if (response.IsSuccessStatusCode)
{
    string responsedone = await response.Content.ReadAsStringAsync();
    var Items = JsonConvert.DeserializeObject<List<OyoSearchData>>(responsedone);
    var ids = Items[0].Hotels.Hotel[0].ID;
}

我得到的答复是：

{StatusCode: 401, ReasonPhrase: 'Unauthorized', Version: 1.1, Content: System.Net.Http.StreamContent, Headers:
{
Connection: close,  Transfer-Encoding
Date: Sat, 22 Jun 2019 05:33:41 GMT
Server: nginx/1.14.1
Transfer-Encoding: chunked
X-Android-Received-Millis: 1561181624449
X-Android-Response-Source: NETWORK 401
X-Android-Selected-Protocol: http/1.1
X-Android-Sent-Millis: 1561181624232
Content-Type: application/json;charset=UTF-8
}}

为什么会出现此错误？我的访问令牌没有与标题一起发送吗？请帮忙。

我尝试过的其他代码是：

public async Task GetOyoApiDataCall(OyoHotelavailability action, bool isNewItem = false)
{
    string resp = null;
    try
    {

        var uri = new Uri(string.Format("https://stg-api.oyorooms.ms/api/v2/hotels/get_availability/"));

        client.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("ACCESS-TOKEN", "c19.......W5XeS0=");
        var json = JsonConvert.SerializeObject(action);
        var content = new StringContent(json, Encoding.UTF8, "application/json");

        HttpResponseMessage response = null;
        if (isNewItem)
        {
            response = client.PostAsync(uri, content).Result;
            resp = response.Content.ToString();//for getting break points
        }
        var resp1 = response.Content.ToString();//for getting break points

        if (response.IsSuccessStatusCode)
        {
            string responsedone = await response.Content.ReadAsStringAsync();
            var Items = JsonConvert.DeserializeObject<List<OyoSearchData>>(responsedone);
            var ids = Items[0].Hotels.Hotel[0].ID;
        }
    }
    catch (Exception e)
    {
    }
}

遇到相同的错误。

您的问题是，根据您的代码，您实际上并未设置以下形式的HTTP标头：

访问令牌：c19 ....... W5XeS0 =

根据代码行client.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("ACCESS-TOKEN", "c19.......W5XeS0=");，您正在做的是创建表单的标题：

授权：ACCESS-TOKEN c19 ....... W5XeS0 =

相反，您需要添加一个名为ACCESS-TOKEN的自定义标头。 @LibinJoseph在这个主题上有一个nice answer。基本上，您只需要用以下形式的行替换有问题的行：

client.DefaultRequestHeaders.Add("ACCESS-TOKEN","c19.......W5XeS0=");

希望对您有帮助！
