Question

我在Google授权方面遇到了一些麻烦，之前我从未使用任何“Google凭据参与”流程。我的问题发生在我创建凭据读取器之后（我假设这意味着我可以正确访问我的Google凭证的json文件），就在我从GoogleNetHTTPTransport实例化新的可信转移的行中。在那里，异常错误抛出：

W/System.err: java.security.KeyStoreException: JKS not found
    at java.security.KeyStore.getInstance(KeyStore.java:649)
    at com.google.api.client.util.SecurityUtils.getJavaKeyStore(SecurityUtils.java:53)
    at com.google.api.client.googleapis.GoogleUtils.getCertificateTrustStore(GoogleUtils.java:74)
    at com.google.api.client.googleapis.javanet.GoogleNetHttpTransport.newTrustedTransport(GoogleNetHttpTransport.java:55)
    at com.example.juans.hasapp.getDataFromSheet.authorize(getDataFromSheet.java:70)

我一直在调查，但仍然无法找到关于这些传输如何工作的正确和明确的解释，或者为什么KeyStore参与了这个过程。

我的代码是我用于从Google表格中获取数据的AsyncTask的一部分，我目前正在尝试访问该表格。在这里，我留下 authorize（）方法，该方法将检索我的凭证以传递给我的SheetsService。

private Credential authorize(Context context) {
    Resources resources = context.getResources();
    InputStream jsonInput = resources.openRawResource(R.raw.credential_info);
    Reader credentialReader = null;
    try {
        credentialReader = new InputStreamReader(jsonInput);
        Log.v("GoogleAut", "credential reader created");
    } catch (NullPointerException n){
        Log.v("ERROR GoogleAut", "filePath came out empty, no info provided");
    }

    GoogleClientSecrets clientSecrets = null;
    try {
        clientSecrets = GoogleClientSecrets
                .load(JacksonFactory.getDefaultInstance(),credentialReader);
    } catch (IOException e) {
        e.printStackTrace();
        Log.v("ERROR GoogleAut","IOException error occurred");
    }

    List<String> scopes = Arrays.asList(SheetsScopes.SPREADSHEETS);

    GoogleAuthorizationCodeFlow flow = null;
    try {
        flow = new GoogleAuthorizationCodeFlow
                .Builder(GoogleNetHttpTransport.newTrustedTransport()
                , JacksonFactory.getDefaultInstance()
                ,clientSecrets
                ,scopes)
                .setDataStoreFactory(new MemoryDataStoreFactory())
                .setAccessType("offline")
                .build();
    } catch (IOException e) {
        e.printStackTrace();
        Log.v("ERROR GoogleAut","IOException error occurred");
    } catch (GeneralSecurityException e) {
        e.printStackTrace();
        Log.v("ERROR GoogleAut","GeneralSecurityException error occurred");
    }

    try {
        return new AuthorizationCodeInstalledApp(flow, new LocalServerReceiver())
                .authorize("user");
    } catch (Exception e) {
        e.printStackTrace();
        Log.v("ERROR GoogleAut", "Unidentified error");
    }
    return null;
}

在此先感谢，我刚开始与谷歌开发，我对学习它的所有可能性非常感兴趣。我也对我的编码提出了任何建议。

以下是帮助我解决此问题的答案 https://stackoverflow.com/a/39249969/8853293 您必须替换

HTTP_TRANSPORT = GoogleNetHttpTransport.newTrustedTransport();

使用

HTTP_TRANSPORT = new com.google.api.client.http.javanet.NetHttpTransport()

尝试使用GoogleNewHTTPTransport时找不到JKS
