在 ASP .NET Core 2.1 Web Api 中启用 CORS [英] Enable CORS in ASP .NET Core 2.1 Web Api
问题描述
我正在使用 ASP .NET Core 2.1 Web API 和 React 编写应用程序.我的服务器在 localhost:5000 上,我的客户端在 localhost:3000 上.我想用 axios 发送 post 请求,但在浏览器控制台中我看到错误:
I'm writting application in ASP .NET Core 2.1 Web API and React. I have my server on localhost:5000 and my client on localhost:3000. I wanted to send post request with axios but in browser console i see error:
OPTIONS https://localhost:5001/api/auth/login 0 ()
Uncaught (in promise) Error: Network Error
at createError (createError.js:16)
at XMLHttpRequest.handleError (xhr.js:87)
在我的 Web API 中,我尝试添加 CORS,但它似乎不起作用.我补充:
In my Web API I try to add CORS but it doesn't seems to work. I add:
public void ConfigureServices(IServiceCollection services)
{
services.AddCors();
services.AddMvc();
...
}
还有:
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
app.UseCors(options =>
options
.AllowAnyOrigin()
.AllowAnyMethod()
.AllowAnyHeader()
.AllowCredentials());
...
app.UseMvc();
}
这是我的帖子请求:
const response = await axios({
method: 'post',
url: 'http://localhost:5000/api/auth/login',
data: {
userName: this.state.controls.login.value,
password: this.state.controls.password.value
}
});
请求后的服务器控制台:
Server console after request:
info: Microsoft.AspNetCore.Hosting.Internal.WebHost[1]
Request starting HTTP/1.1 OPTIONS http://localhost:5000/api/auth/login
info: Microsoft.AspNetCore.Cors.Infrastructure.CorsService[4]
Policy execution successful.
info: Microsoft.AspNetCore.Hosting.Internal.WebHost[2]

Policy execution successful.

Request finished in 2.1805ms 307
info: Microsoft.AspNetCore.Server.Kestrel[32]
Connection id "0HLG4CH3JIV16", Request id "0HLG4CH3JIV16:00000002": the application completed without reading the entire request body.
当我使用 Postman 时一切正常.我从服务器收到带有令牌的 json.
When I use Postman everything is fine. I receive json with token from server.
推荐答案
好的,我解决了我的问题.我只是不知道我应该删除app.UseHttpsRedirection();".
Ok, I resolve my problem. I just didn't know that I should remove "app.UseHttpsRedirection();".
