android - 在 Retrofit2 API 值传递问题中需要帮助

Question

按下登录按钮后，只有这部分 url http://127.0.0.1/AdminaService/AdminaService.svc/Verify_User_And_Password_For_login已通过，请参阅我的日志。edttxt 字段中的值未添加或传递。

[我的 api] http://127.0.0.1/AdminaService/AdminaService.svc/Verify_User_And_Password_For_login/ {PUSER_ID}/{PPASSWORD}/{PUSER_SESSION_ID}/{PIPADDRESS}/{PAPPLICATION_ID}

1,2 定义有效或无效。json 格式 { "VerifyUserAndPasswordForLoginResult": "1" }

public class LoginActivity extends AppCompatActivity {

                LoginUser loginUser =response.body();
                if(response.isSuccessful()){
                    Toast.makeText(LoginActivity.this,"Logged id",Toast.LENGTH_LONG).show();

            return (mobile != null && mobile.isConnectedOrConnecting()) || (wifi != null && wifi.isConnectedOrConnecting());

        builder.setMessage("You need to have Mobile Data or wifi to access this. Press ok to Exit");

        builder.setPositiveButton("Ok",new DialogInterface.OnClickListener() {

            @Override

            }
        });

        return builder;
    }


}

界面

public interface ApiInterface {



    @FormUrlEncoded
    @POST("Verify_User_And_Password_For_login/")
    Call<LoginUser> login(@Query("{PUSER_ID}") String user_id ,@Query("{PPASSWORD}") String pass);
}

APIUtils

public class ApiUtils {

    private static final String Base_url="http://127.0.0.1/AdminaService/AdminaService.svc/";

    public static ApiInterface getapiInterface(){
        return RetrofitClient.getClient(Base_url).create(ApiInterface.class);
    }
}

Pojo类：

public class LoginUser {


        @SerializedName("VerifyUserAndPasswordForLoginResult")
        @Expose
        private String verifyUserAndPasswordForLoginResult;

        public String getVerifyUserAndPasswordForLoginResult() {
            return verifyUserAndPasswordForLoginResult;
        }

        public void setVerifyUserAndPasswordForLoginResult(String verifyUserAndPasswordForLoginResult) {
            this.verifyUserAndPasswordForLoginResult = verifyUserAndPasswordForLoginResult;
        }


}

由于这是一个发布请求，我认为您应该使用 @Field 而不是查询或路径。您的方法声明如下所示：

 @FormUrlEncoded
 @POST("Verify_User_And_Password_For_login/")
 Call<LoginUser> login(@Field("PUSER_ID") String user_id ,@Field("PPASSWORD") String pass);

将值作为方法调用传递。
