POST Json Web API C#

Question

我正在尝试在C# 中通过HTTP 客户端发布api，对于授权，我们发送Bearer 令牌。 但它没有被插入客户端。它会引发错误。

我的代码在这里：

ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3 | SecurityProtocolType.Tls12 | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls;
            string result = "";
            using (var client = new HttpClient(new HttpClientHandler() { UseDefaultCredentials = true }))
            {
                client.BaseAddress = new Uri(baseURL);
                client.DefaultRequestHeaders.Accept.Clear();
                client.DefaultRequestHeaders.Add("Cookie", "ebpPermHash=-396055074);
                client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
                client.DefaultRequestHeaders.Add("Authorization", "Bearer " + authtoken);
                client.DefaultRequestHeaders.Add("Accept-Encoding", "gzip, deflate");
                client.DefaultRequestHeaders.Add("Accept-Language", "en-GB,en-US;q=0.9,en;q=0.8");
                client.DefaultRequestHeaders.Add("Cache-Control", "no-cache")
                client.DefaultRequestHeaders.Add("User-Agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/69.0.3497.100 Safari/537.36");
                client.DefaultRequestHeaders.Add("Accept", "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8");
                
                HttpResponseMessage response = client.PostAsJsonAsync("/v2/bb/sa", payModel).Result;
                
                var responseString = response.Content.ReadAsStringAsync();
                result = responseString.Result;
                dynamic data = JObject.Parse(result);
                string throwresult = Convert.ToString(data);
                result = data.authToken;
                logErr.ControlLog(throwresult);
            }
            return result;

但我收到如下错误：

exceptionType": "com.ebpsource.exception.AuthenticationFailedException",
  "name": "AUTHENTICATION_REQUIRED",
  "message": "Authentication is required to call 'Resource.execute'",
  "address": "/service/Resource.execute",
  "httpRequestBody": {
    "header": {
      "config": {
        "action": "insert",
        "resourceName": "sa"
      }

提前致谢。

我建议你先用 Postman 检查你的后端，确认是后端问题还是客户端问题

Answer 2

你有一个错误，添加标记的语法错误。再加上许多标题。试试这个

using (var client = new HttpClient())
{

client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", token);        
var contentType = new MediaTypeWithQualityHeaderValue("application/json");  
client.DefaultRequestHeaders.Accept.Add(contentType);
client.BaseAddress = new Uri(baseAddress);
var jsonData = JsonConvert.SerializeObject(payModel);
var contentData = new StringContent(jsonData, Encoding.UTF8, "application/json");
var response =  client.PostAsync("/v2/bb/sa", contentData).Result;
if (response.IsSuccessStatusCode)
{
var stringData = response.Content.ReadAsStringAsync().Result;
var result = JsonConvert.DeserializeObject<object>(stringData);
}
}

更新

如果你需要添加 cookie，你可以这样做

var cookieContainer = new CookieContainer();
using (var handler = new HttpClientHandler() { CookieContainer = cookieContainer })
using (var client = new HttpClient(handler))
{
    ....
    cookieContainer.Add(baseAddress, new Cookie("CookieName", "cookie_value"));
.....
}
