Question

我发布了一封电子邮件和密码，以便我收到回复。

@FormUrlEncoded
    @POST("api-token-auth/")
    Observable<AccessToken> getAccessToken(@Field("username") String email, @Field("password") String password);

然后我在演示者中运行代码。

 subscription = getAccessTokenUseCase.execute()
                .subscribeOn(Schedulers.newThread())
                .observeOn(AndroidSchedulers.mainThread())
                .subscribe(new Subscriber<AccessToken>() {
                    @Override
                    public void onCompleted() {

                        Log.v("token",accessToken.getAccessToken());
                        sharedPrefsWrapper.putString("token",accessToken.getAccessToken());
                    }

                    @Override
                    public void onError(Throwable e) {

                    }

                    @Override
                    public void onNext(AccessToken accessToken) {

                    }
                });

由于access.getAccessToken（），我得到了一个nullpointerexception。

然而，日志显示已收到令牌。

如何保存令牌？编辑：

public class AccessToken {
    @SerializedName("venue")
    @Expose
    private String AccessToken;

    public String getAccessToken() {
        return AccessToken;
    }
}

Answer 1

从日志看起来，令牌的关键是＆＃34;令牌＆＃34;而不是＆＃34;场地＆＃34;。因此，将AccessToken模型修改为此

public class AccessToken {
    @SerializedName("token")
    @Expose
    private String accessToken;

    public String getAccessToken() {
        return accessToken;
    }
}

如何从Android中的演示者访问令牌？
