尝试到达应用引擎端点时发生SSLHandshakeException [英] SSLHandshakeException when trying to reach app engine endpoint

问题描述

我尝试连接到我的一个端点方法从一个Android客户端到我本地运行的应用程序引擎后端。问题是我收到一个SSLHandshakeException。我的API不受OAuth保护。我想达到的方法看起来像这样：

I'm trying to connect to one of my endpoint methods from an android client to my locally running app engine backend. The problem is I'm getting a SSLHandshakeException. My API is not protected by OAuth. The method I am trying to reach looks like this:

@ApiMethod(name = "register")
public UserInfo registerUser(UserInfo userInfo) {
    try {
        checkUserParameters(userInfo);
        ofy().save().entity(userInfo).now();
        return ofy().load().entity(userInfo).now();
    } catch (InvalidPropertiesFormatException e) {
        logger.info(e.getMessage());
        return null;
    }
}

从我的客户端我这样做： p>

And from my client I am doing this:

  if (regService == null) {
            UserInfoApi.Builder builder = new UserInfoApi.Builder(AndroidHttp.newCompatibleTransport(),
                   new AndroidJsonFactory(), null)
                .setRootUrl(LoginActivity.LOCALHOST_IP)
                .setGoogleClientRequestInitializer(new GoogleClientRequestInitializer() {
                    @Override
                    public void initialize(AbstractGoogleClientRequest<?> abstractGoogleClientRequest)
                            throws IOException {
                        abstractGoogleClientRequest.setDisableGZipContent(true);
                    }
           });

           regService = builder.build();
           UserInfo userInfo = new UserInfo();
           userInfo.setGcmId(registerToGcm());
           userInfo.setAccountName(params[0]);
           userInfo.setEmail(params[0]);
           userInfo.setProfilePictureUrl(null);
           UserInfo userInfo = regService.register(userInfo).execute();
  }

由于某些原因，这不工作，我也尝试了API你得到当导入后端模块到android studio，但它给出了相同的错误。

For some reason this does not work, I have also tried with the API that you get when importing the backend module to android studio but it gives the same error.

推荐答案

问题是我在客户端上设置rootUrl时使用https而不是http。

So... The problem was I was using https instead of http when setting rootUrl on the client.
