本地PC上从Angular应用程序发布到ASP.NET核心API的CORS

我有一个本地运行的ASP.NET核心API服务和一个本地Angular应用程序。我的大多数调用对API来说都很好,但是一个调用总是给我带来CORS错误。我怀疑是因为这是一个术后手术?根据CORS,帖子需要什么不同的内容吗?

Anuglar ts:

loadGroup(groupName:string){
    this.apiService.getInfluencersWithFilter(this.query,groupName,null,null,this.ageRanges).subscribe((data) => {     
      this.influencerSearchResult = data.results;
      // this.searchGroupsFacet = data.facetGroupList;
      this.searchSubGroupsFacet = data.facetSubGroupList;
      this.showSubGroups = true;

   });
  }

角度服务:

getInfluencersWithFilter(q:string, group:string, subGroups:string[], socialAccounts:string[],ageRanges:AgeRange[]):Observable<InfluencerSearchContainer>
{    
        if(q==null)
        {
          q = "";
        }
        var url = `${environment.apiDomain}/api/InfluencersSearch/`;
        return  this.httpClient.post<InfluencerSearchContainer>(url,{q:"",group:group,subGroups:subGroups, socialAccounts:socialAccounts, ageRanges:ageRanges}).pipe(
          map(x => new InfluencerSearchContainer(x)));      
 }

启动ASP.NET核心:

public void ConfigureServices(IServiceCollection services)
    {
        services.AddScoped<DocumentClient>((s) =>
        {
            string EndpointUrl = Configuration["CosmosDB:EndpointUrl"];
            string PrimaryKey = Configuration["CosmosDB:PrimaryKey"];
            return new DocumentClient(new Uri(EndpointUrl), PrimaryKey);
        });

        var connStr = Configuration.GetConnectionString("DefaultConnection");
        services.AddDbContext<DB>(options => options.UseSqlServer(connStr));

        services.AddCors(options =>
        {
            options.AddPolicy("AllowSpecificOrigin",
                builder => builder.AllowAnyOrigin()
                       .AllowAnyHeader()
                       .AllowAnyMethod());
        });

        services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);
    }

  public void Configure(IApplicationBuilder app, IHostingEnvironment env)
    {
        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
        }
        else
        {
            app.UseHsts();
        }

        app.UseCors("AllowSpecificOrigin");
        app.UseHttpsRedirection();
        app.UseMvc();
    }

和控制器:

  [HttpPost]
    public InfluencerSearchResultWithFacets Post([FromBody] InfluencerQuery q)
    {
        return GetSearchResult(q.q, q.group,q.subGroups, q.socialAccounts, q.ageRanges);
    }

我有什么东西不见了吗?我想这里什么都是残疾人?在我写这篇文章的时候,我怀疑它和文章有点关系,因为get操作有效。

邮递员的工作原理是:

我还在控制器上添加了以下内容: [启用CORS(“allowSpecificOrigin”)]
