.net framework c# web api, send username and password as string array in body from postman

Question

我尝试使用下面的代码从正文中读取用户名/密码，但我得到的只是“对象引用未设置为对象的实例”代码 API：

[Route("api/login_test")]
[HttpGet]
public object login_test([FromBody] string[] Username_Password])
{
    string UsernameOrEmail_address, Password;
    UsernameOrEmail_address = Username_Password[0];
    Password = Username_Password[1];

    return UsernameOrEmail_address  + " " + Password;
}

Answer 1

通过更改 Http 请求它工作，从 HttpGet 替换为HttpPost

[Route("api/login_test")]
[HttpPost]
public object login_test([FromBody] string[] Username_Password])
{
    string UsernameOrEmail_address, Password;
    UsernameOrEmail_address = Username_Password[0];
    Password = Username_Password[1];

    return UsernameOrEmail_address  + " " + Password;
}
