java.lang.IllegalArgumentException:无法为接口改装创建调用适配器。调用

java android

java.lang.IllegalArgumentException:无法为接口改装创建调用适配器。调用,java,android,retrofit,Java,Android,Retrofit,myVSApiEndpointInterface中的代码 @POST(REGISTER_USER) Call registerUser(@Body User user); 用户类如下所示 public class User { String email; String password; public User(String email, String password) { this.email = email; this.passw

myVSApiEndpointInterface中的代码

@POST(REGISTER_USER)
Call registerUser(@Body User user);
用户类如下所示

public class User {
    String email;
    String password;

    public User(String email, String password) {
        this.email = email;
        this.password = password;
    }
}
在主活动中，我以用户为对象

User user = new User("hello_new_user@gmail.com", "123456");


Call call = apiService.registerUser(user);
                call.enqueue(new Callback<User>() {
                    @Override
                    public void onResponse(Response<User> response, Retrofit retrofit) {
                        int statusCode = response.code();
                        System.out.print("Veer " +response.body());
                    }

                    @Override
                    public void onFailure(Throwable t) {
                        // Log error here since request failed
                    }
                });

User User=new User（“你好”\u new_user@gmail.com", "123456");
Call Call=apiService.registerUser（用户）；
call.enqueue（新回调（）{
@凌驾
公共响应（响应、改装）{
int statusCode=response.code（）；
System.out.print（“Veer”+response.body（））；
}
@凌驾
失效时的公共无效（可丢弃的t）{
//由于请求失败，此处记录错误
}
});
我也试过,

Call<User> registerUser(@Body User user);

callregisteruser（@Body User）；
但同样的错误

全程

问题是因为职业后卫的规则

这就是帮助我的原因



这里的改装和Okio规则对我很有用。
包括完整的堆栈跟踪HTTP POST返回什么？如果它返回一个JSON数据，那么创建一个与返回JSON匹配的POJO，并相应地将方法签名更改为return
Call
Hi，您能检查一下这个问题吗
