[英]Using Blazor Client-Side consuming Web API with Windows Authentication
Currently I've got an application running with and angular client, consuming a Web API with Windows Authentication.目前,我有一个使用 angular 客户端运行的应用程序,使用带有 Windows 身份验证的 Web API。
Now I'm looking into replacing this front end with Blazor (client-side), however I'm facing some challenges when it comes to authentication.现在我正在考虑用 Blazor(客户端)替换这个前端,但是在身份验证方面我面临一些挑战。
In angular I just set withCredentials to true in order to submit the required information.在 angular 中,我只是将 withCredentials 设置为 true 以提交所需的信息。
The code below works as intended using Blazor server-side, but since I want to use Blazor client-side it's not an option and doesn't help me much.下面的代码使用 Blazor 服务器端按预期工作,但由于我想使用 Blazor 客户端,因此它不是一个选项,对我帮助不大。
IEnumerable<SearchView> searchResults;
int NumberOfItems;
protected override async Task OnInitAsync()
{
using (var client = new HttpClient(new HttpClientHandler() { UseDefaultCredentials = true }))
{
var result = await client.GetJsonAsync<Response<SearchView>>("http://localhost:80/search");
NumberOfItems = result.TotalItemCount;
searchResults = result.Items;
}
}
}
The above code throws an "PlatformNotsupportedException".上面的代码抛出一个“PlatformNotsupportedException”。
WASM: System.PlatformNotSupportedException: System.Net.Http.HttpClientHandler is not supported on the current platform. WASM:System.PlatformNotSupportedException:当前平台不支持 System.Net.Http.HttpClientHandler。 WASM: at System.Net.Http.HttpClientHandler.set_UseDefaultCredentials (System.Boolean value) <0x1d63160 + 0x0000c> in <4399d2484a2a46159ade8054ed94c78e>:0 WASM:在 System.Net.Http.HttpClientHandler.set_UseDefaultCredentials(System.Boolean 值)<0x1d63160 + 0x0000c> 在 <4399d2484a2a46159ade8054ed94c78e>:0
Clearly the code provided is not supported using Blazor client-side, but if there are any alternative ways to achieve what I want to, any pointers and help would be appreciated.显然,使用 Blazor 客户端不支持提供的代码,但如果有任何其他方法可以实现我想要的目标,任何指针和帮助将不胜感激。
I've just hit the same problem and couldn't get it working with HttpClient, but I did manage it with a HttpRequestMessage:我刚刚遇到了同样的问题,无法与 HttpClient 一起使用,但我确实使用 HttpRequestMessage 对其进行了管理:
string APIURL = "https://localhost:44390/api/models";
// create request object and pass windows authentication credentials
var request = new HttpRequestMessage(HttpMethod.Get, APIURL);
request.SetBrowserRequestCredentials(BrowserRequestCredentials.Include);
// send the request and convert the results to a list
var httpResponse = await Http.SendAsync(request);
models = await httpResponse.Content.ReadFromJsonAsync<myModel[]>();
This is not (yet) possible.这(还)不可能。 Blazor client-side runs on the Mono runtime of the .net framework which does not support Windows Authentication. Blazor 客户端在不支持 Windows 身份验证的 .net 框架的 Mono 运行时上运行。
Your best option is to implement a token based auth (JWT for instance) and use ADFS.您最好的选择是实施基于令牌的身份验证(例如 JWT)并使用 ADFS。
