为什么Android射击库无法连接ASP.NET Web API？

Question

我正在尝试使用射击库从Android客户端调用ASP.NET Web API。 .NET API工作正常，听力端口是： http：// localhost：5000和https：// localhost：5001在我的本地计算机中。

但是，当我尝试运行Android客户端时，将基本URL保持为 http:/10.0.2.2:5000 /api/login 我在Console-＆gt;中发现以下错误。

在ASP.NET Web api-＆gt;中登录的控制器类

namespace TourExpWIP1.Controllers
{
    [Route("api/[controller]")]
    [ApiController]
    public class LoginController : ControllerBase
    {
        NetCoreAuthenticationContext dbContext = new NetCoreAuthenticationContext();

        public string Post([FromBody] TblUser  value)
        {
            
            if (dbContext.TblUser.Any(user => user.UserName.Equals(value.UserName)))
            {
                TblUser user = dbContext.TblUser.Where(u => u.UserName.Equals(value.UserName)).First();
                var client_post_hash_password = Convert.ToBase64String(
                    Common.SaltHashPassword(
                        Encoding.ASCII.GetBytes(value.Password),
                        Convert.FromBase64String(user.Salt)));
                if (client_post_hash_password.Equals(user.Password))
                    return JsonConvert.SerializeObject(user);
                else return JsonConvert.SerializeObject("Wrong Password");
            }
            else
            {
                return JsonConvert.SerializeObject("user does not exists in db");
            }
        }
    }
}

Answer 1

尝试此

1.在Android清单中，在标签应用程序中添加：
内部标记应用程序添加此标签：

<uses-library android:name="org.apache.http.legacy" android:required="false"/>

<application
    android:usesCleartextTraffic="true"
    android:networkSecurityConfig="@xml/network_security_config"
...
/>

2。app/src/src/main/res/xml/的相应网络_security_config.xml：

<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
    <base-config cleartextTrafficPermitted="true" />
</network-security-config>
