角過賬到ASP.NET核心Web API恢復故障

Question

這是我在網上API

// POST api/Values 
    [HttpPost] 
    public async Task Post() 
    { 
     string user = new StreamReader(Request.Body).ReadToEnd(); 
     var cmd = new SqlCommand(
       @"insert into Users 
       select * 
       from OPENJSON(@user) 
       WITH(Username, Password, Email, Nickname, IsActive, Activation)"); 
     cmd.Parameters.AddWithValue("user", user); 
     await SqlCommand.ExecuteNonQuery(cmd); 
    } 

代碼，這是我的角度JS

data = JSON.stringify({Username: user, Password: pwd, Nickname: user, IsActive: '1', Activation: '2u4bubdub32939342'}); 
     $http.post('http://localhost:7792/api/values', data) 
     .success(function(data, status, headers, config) { 
      alert("success"); 
     }) 
     .error(function(data, status, headers, config) { 
      alert("failure message: " + data + " " +status+ " " +headers+ " " +config); 
     }); 
     } catch (e) { alert(e.message); } 

當我運行它

代碼，我獲取失敗消息。我已經在網絡啓用COR APO

Answer 1

你的POST方法應採取一個參數，用戶模型，你是正確的，通過角發送。我希望這個example可以幫助你。

Answer 2

谷歌搜索在startup.cs

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

，我也加入到配置Web我加入到我的ConfigureServices（IServiceCollection服務）（IApplicationBuilder應用，後...在startup.cs

 app.UseCors("CorsPolicy");
