Aurelia Fetch 客户端 - 不支持的媒体类型 - .NET Core WebAPI
Aurelia Fetch Client - Unsupported Media Type - .NET Core WebAPI
当我尝试 post 两个参数作为 JSON 使用 Aurelia Fetch Client 到 .NET Core WebAPI 我得到:415 (Unsupported Media Type)
ApplicationController
[HttpPost("getapplications")]
public ApplicationViewModel GetApplications([FromBody] ApplicationSearchModel model)
{
var applications = _applicationService.GetApplications().ToList();
return new ApplicationViewModel()
{
Applications = applications
};
}
public class ApplicationSearchModel
{
public DateTime? From { get; set; }
public DateTime? To { get; set; }
}
application.js
import { inject } from 'aurelia-framework';
import {HttpClient, json} from 'aurelia-fetch-client';
@inject(HttpClient)
export class Application {
constructor(httpClient) {
this.applications = [];
this.httpClient = httpClient;
}
getApplications() {
this.httpClient.fetch("http://localhost:9001/api/application/getapplications", {
method: "POST",
body: JSON.stringify({
From: '2017-02-18',
To: '2017-02-18'
}),
headers: {
"content-type": "application/json; charset=utf-8" //Tried without headers aswell
}
});
}
activate(params) {
this.getApplications();
}
}
如果我删除 [FromBody]
它 posts 但我的 ApplicationSearchModel
中的属性是空的。
当我使用以下设置与 Postman 进行 post 编辑时:
Url:
http://localhost:9001/api/application/getapplications
Body:
{
"from": "2017-02-18",
"to": "2017-02-18"
}
Header:
Content-Type: application/json
一切正常,我在 ApplicationSearchModel
中的属性不为空。
当我查看 Aurelia Fetch Client 生成的请求时,似乎缺少 Content-Type header..
编辑
请求Headers:
Accept:*/*
Accept-Encoding:gzip, deflate, sdch, br
Accept-Language:en-US,en;q=0.8
Access-Control-Request-Headers:content-type
Access-Control-Request-Method:POST
Connection:keep-alive
Host:localhost:9001
Origin:http://localhost:9000
Referer:http://localhost:9000/

您的 headers 设置不正确。
应该是
{
"content-type": "application/json; charset=utf-8"
}
而不是
{
"content-type", "application/json; charset=utf-8"
}
..原来是CORS问题
我在 Startup.cs 中添加了 cors 设置以允许所有来源:
// This method gets called by the runtime. Use this method to add services to the container
public void ConfigureServices(IServiceCollection services)
{
//CORS---------
services.AddCors(options =>
{
options.AddPolicy("CorsPolicy",
builder => builder.AllowAnyOrigin()
.AllowAnyMethod()
.AllowAnyHeader()
.AllowCredentials());
});
// Add framework services.
services.AddApplicationInsightsTelemetry(Configuration);
services.AddMvc();
}
// This method gets called by the runtime. Use this method to configure the HTTP request pipeline
public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
//CORS---------
app.UseCors("CorsPolicy");
loggerFactory.AddConsole();
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
app.UseMvc();
app.UseDefaultFiles();
app.UseStaticFiles();
// app.UseStaticFiles(new StaticFileOptions()
// {
// FileProvider = new PhysicalFileProvider(
// Path.Combine(Directory.GetCurrentDirectory(), "src")),
// RequestPath = new PathString("/src")
// });
}
一切正常..
我的 Aurelia 应用程序托管在 port:9000 上,我的 .NET 应用程序托管在 port:90001 上.我的想法是在应用程序发布后从我的 .NET 应用程序提供静态页面,但现在在开发中我使用 port:9000 因为 Aurelia 提供的 BrowserSync,(CORS 不会发布时是个问题,但现在在本地使用 port:9000 时是个问题。
是否可以在本地使用 port:9000 而不启用 CORS?
编辑:
仅在本地主机上启用 CORS:
app.UseCors(builder =>
{
builder.WithOrigins("http://localhost:9000")
.AllowAnyMethod()
.AllowAnyHeader()
.AllowCredentials();
});
