目标: 实现一个程序(java 或 python)来从我在我的 Youtube 频道上发布的视频中检索数据。该程序将每天(凌晨 1:00)启动。
解决方案: 要检索 Youtube 数据,包括每天的观看次数,我认为 YouTube Analytics API 是最好的解决方案。我使用 Google 帐户服务(“GoogleCredential”)对我进行身份验证:
static {
// Build service account credential.
try {
// Create a listener for automatic refresh OAuthAccessToken
List<CredentialRefreshListener> list = new ArrayList<CredentialRefreshListener>();
list.add(new CredentialRefreshListener() {
public void onTokenResponse(Credential credential,
TokenResponse tokenResponse) throws IOException {
System.out.println(tokenResponse.toPrettyString());
}
public void onTokenErrorResponse(Credential credential,
TokenErrorResponse tokenErrorResponse)
throws IOException {
System.err.println("Error: "
+ tokenErrorResponse.toPrettyString());
}
});
// Create a GoogleCredential for authenticate with ServiceAccount
// service
credential = new GoogleCredential.Builder()
.setTransport(HTTP_TRANSPORT)
.setJsonFactory(JSON_FACTORY)
.setServiceAccountId(SERVICE_ACCOUNT_EMAIL)
.setServiceAccountScopes(SCOPES)
.setClock(Clock.SYSTEM)
.setServiceAccountPrivateKeyFromP12File(
new File("key.p12"))
.setRefreshListeners(list).build();
credential.refreshToken();
} catch (GeneralSecurityException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
我执行 Youtube Analytics 查询:
YoutubeAnalytics youtubeAnalytics = new YoutubeAnalytics.Builder(HTTP_TRANSPORT, JSON_FACTORY, credential)
.setApplicationName("Test-YouTube-Analytics/1.0").build();
// Create request
credential.refreshToken();
YoutubeAnalyticsRequest<?> request = youtubeAnalytics.reports()
.query("channel==" + channelId, "2012-10-01", "2012-12-01", "views")
.setAlt("json")
.setKey(API_KEY)
.setDimensions("month")
.setPrettyPrint(true);
System.out.println(request.buildHttpRequest().getUrl().toString());
ResultTable first = (ResultTable) request.execute();
}
但我收到以下错误:
com.google.api.client.googleapis.json.GoogleJsonResponseException: 500 Internal Server Error
{
"code" : 500,
"errors" : [ {
"domain" : "global",
"message" : "Unknown error occurred on the server.",
"reason" : "internalError"
} ],
"message" : "Unknown error occurred on the server."
}
感谢您的洞察力!
