它是我的Android代码:-

Its my Android Code:-

package com.example.ankit.postrequest;

public class DataSent extends AppCompatActivity {

    private static final String KEY_USERNAME ="rohit" ;
    private static final String KEY_PASSWORD ="1234" ;
    private static final String KEY_EMAIL ="[e-mail]" ;
    private static final String KEY_token ="xyz" ;
    EditText Etname,Etpass,Etmail,Et_token;
    RequestQueue insert;
    String insertUrl ="http://memorableshaadi.com/j";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

    }

    public void call(View v) {
          registerUser();
    }

    private void registerUser(){
        final String username = Etname.getText().toString().trim();

        final String email = Etmail.getText().toString().trim();
        final String token = Ettoken.getText().toString().trim();

        StringRequest stringRequest = new StringRequest(Request.Method.POST, insertUrl,
                new Response.Listener<String>() {
                    @Override
                    public void onResponse(String response) {
                        Toast.makeText(DataSent.this, response, Toast.LENGTH_LONG).show();
                    }
                },
                new Response.ErrorListener() {
                    @Override
                    public void onErrorResponse(VolleyError error) {
                        Toast.makeText(DataSent.this,error.toString(),Toast.LENGTH_LONG).show();
                    }
                }){
            @Override

                Map<String,String> params = new HashMap<String, String>();

                return params;
            }

        };

        RequestQueue requestQueue = Volley.newRequestQueue(this);
        requestQueue.add(stringRequest);

推荐答案

您应该注意两件事: 首先:您面临的错误是: VerifyCsrfToken.php中的TokenMismatchException，其原因是因为要构建身份验证，任何请求都应通过中间件传递，并且必须通过Laravel令牌传递，因此由于您使用的是post方法，因此未传递它，因此它丢失了您的请求，所以这是最简单的方法修复将异常添加到您的App \ Http \ Middleware \ VerifyCsrfToken.php

There are two things you should take care of : First : The error you're facing is : TokenMismatchException in VerifyCsrfToken.php and the reason is because to build an authentication any request should passthrough your middleware and in Laravel Token must be passed so since you are using the post method you didn't pass it and it's missing your request so the easiest way to fix that is to add exceptions to your App\Http\Middleware\VerifyCsrfToken.php

class VerifyCsrfToken extends BaseVerifier
{
/**
 * The URIs that should be excluded from CSRF verification.
 *
 * @var array
 */
protected $except = [
   /* Add here your URLs */ 
];
}

您的请求将正常工作，并且您也可以使用此库来处理令牌身份验证 jwt-auth . 但是，关于您的代码，我应该提到一些事情: 在您的android代码中:

And your request will work just fine, and also you can use this library for handling Token Authentication jwt-auth. However there is something I should mention about your code: In your android code :

private static final String KEY_USERNAME ="rohit" ;
private static final String KEY_PASSWORD ="1234" ;
private static final String KEY_EMAIL ="[e-mail]" ;
private static final String KEY_token ="xyz" ;

这些键将用于将请求的值与检查函数的值进行匹配，因此您应首先将它们重命名为与API源一样，否则检查函数将无法从任何请求中获取值 所以他们应该像这样:

These keys will be used to match the request's values with the check function's values so you should first rename them to be just like the API source otherwise the check function won't get the values from any request so they should be like so :

private static final String KEY_USERNAME ="username" ;
private static final String KEY_PASSWORD ="password" ;
private static final String KEY_EMAIL ="email" ;
