我想用Xamarin表单应用程序连接到Axelor服务器，我使用这个方法来测试其余服务的连通性:
Login login = new()
{
UserName = Constants.Login,
Password = Constants.Password
};
// Build authentication string
byte[] bytes = Encoding.UTF8.GetBytes($"{login.UserName}:{login.Password}");
string authorizationString = Convert.ToBase64String(bytes);
// Add headers to the HTTP client
httpClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", authorizationString);
// Build HTTP message and send, strRoot = login.jsp
string url = $"{Constants.RestBaseUrl}/{strRoot}";
HttpRequestMessage message = new HttpRequestMessage(HttpMethod.Post, url);
var sessionResponse = await httpClient.SendAsync(message);
/* sessionResponse.IsSuccessStatusCode = true, and sessionResponse.Headers =
{
Set-Cookie: JSESSIONID=E5EA31C3A5CBDF0A1C4B05ED2230679E; Path=/Gradle___com_axelor___axelor_erp_6_3_0_war; HttpOnly
Date: Mon, 14 Nov 2022 19:40:04 GMT
}
*/
sessionResponse.Headers.ToList().ForEach(x =>
httpClient.DefaultRequestHeaders.Add(x.Key, x.Value.FirstOrDefault()));
var rt = $"{Constants.RestBaseUrl}/ws/rest/com.axelor.apps.poultryfarming.db.Hatchery";
var response = await httpClient.GetAsync(rt);
var returnValue = await response.Content.ReadAsStringAsync();
/* returnValue :
<!doctype html><html lang="en"><head><title>HTTP Status 401 – Unauthorized</title><style type="text/css">body {font-family:Tahoma,Arial,sans-serif;} h1, h2, h3, b {color:white;background-color:#525D76;} h1 {font-size:22px;} h2 {font-size:16px;} h3 {font-size:14px;} p {font-size:12px;} a {color:black;} .line {height:1px;background-color:#525D76;border:none;}</style></head><body><h1>HTTP Status 401 – Unauthorized</h1><hr class="line" /><p><b>Type</b> Status Report</p><p><b>Description</b> The request has not been applied because it lacks valid authentication credentials for the target resource.</p><hr class="line" /><h3>Apache Tomcat/8.5.73</h3></body></html>
*/
var stat = response.StatusCode; // return: Unauthorized
var cc = response.IsSuccessStatusCode;
return returnValue;
}
catch (Exception e)
{
throw;
}
但是我总是得到未经授权的状态!
你能帮我一下吗
当我用导航器测试时，我有这样的正确响应:
与RestSharp.RestRequest一起工作得很好!
使用RestClient调用Axelor rest服务示例:https://github.com/dalmed/Maui-Axelor-Mobile.git
这是我的解决方案:
public class RestClientService : IRestClientService
{
//private readonly ILogger<RestClientService> _logger;
public RestClientService()
{
//_logger = logger;
}
public async Task<bool> LoginAsync(Login login)
{
string jsonString = JsonSerializer.Serialize(login);
try
{
Constants.Cookies = null;
Constants.IsServerConnected = false;
var uri = new Uri($"{Constants.RestBaseUrl}/login.jsp");
var _RestClient = new RestClient(uri);
var request = new RestRequest(uri, Method.Post);
request.AddHeader("Content-Type", "application/json");
request.AddParameter("application/json", login, ParameterType.RequestBody);
RestResponse response = await _RestClient.ExecuteAsync(request);
if (response.IsSuccessStatusCode)
{
Constants.Cookies = response.Cookies;
Constants.IsServerConnected = true;
}
return response.IsSuccessStatusCode;
}
catch (Exception e)
{
// _logger.LogError(e, "LoginError");
throw;
}
}
public async Task<RootData<T>> RestServiceGetAsync<T>(string model, int offset = 0, int limit = 10)
{
try
{
var uri = $"{Constants.RestBaseUrl}/ws/rest/{model}";
var _RestClient = new RestClient(uri);
var request = new RestRequest(uri, Method.Get);
request.AddHeader("Content-Type", "application/json");
if (Constants.Cookies.Any() && Constants.IsServerConnected)
{
string cookie = "";
Constants.Cookies.ToList().ForEach(x => cookie += $"{x.Name}={x.Value}; ");
request.AddHeader("Cookie", cookie);
}
else
{
throw new Exception("The server is not connected !");
}
request.AddParameter("offset", offset, ParameterType.UrlSegment);
request.AddParameter("limit", limit, ParameterType.UrlSegment);
RestResponse response = await _RestClient.ExecuteAsync(request);
if (response.IsSuccessStatusCode)
{
var data = new MemoryStream(Encoding.UTF8.GetBytes(response.Content));
var rslt = await JsonSerializer.DeserializeAsync<RootData<T>>(data);
return rslt;
}
return null;
}
catch (Exception e)
{
//_logger.LogError(e, $"GetModelError: {model}");
throw;
}
}
public async Task<bool> LogoutAsync()
{
try
{
var uri = $"{Constants.RestBaseUrl}/logout";
var _RestClient = new RestClient(uri);
var request = new RestRequest(uri, Method.Get);
request.AddHeader("Content-Type", "application/json");
if (Constants.Cookies.Any() && Constants.IsServerConnected)
{
string cookie = "";
Constants.Cookies.ToList().ForEach(x => cookie += $"{x.Name}={x.Value}; ");
request.AddHeader("Cookie", cookie);
}
else
{
throw new Exception("The server is not connected !");
}
RestResponse response = await _RestClient.ExecuteAsync(request);
return response.IsSuccessStatusCode;
}
catch (Exception e)
{
//_logger.LogError(e, "LogoutError");
throw;
}
}
}
