表示使用的OAuth2服務（服務器到服務器）的任何樣品佔

Question

所有心中已經看到，其中用戶必須存在僅支持「用戶」帳戶的樣品。

貌似OAuth2用戶的最新版本支持服務帳戶服務器到服務器的身份驗證在人類不在場，但我在努力尋找支持，或在使用實例的庫。

Answer 1

我不（還）必須通過服務帳戶授權的任何C＃示例，但谷歌API的支持服務帳戶授權流程。這裏是（使用與谷歌的BigQuery API此授權流程，在Java & Python中，使用谷歌API客戶端庫爲這些語言的例子http://code.google.com/p/google-api-python-client/和http://code.google.com/p/google-api-java-client/）。用Python實現

import com.google.api.client.http.HttpTransport; 
import com.google.api.client.http.javanet.NetHttpTransport; 
import com.google.api.client.json.JsonFactory; 
import com.google.api.client.json.jackson.JacksonFactory; 

import com.google.api.client.googleapis.auth.oauth2.GoogleCredential; 
import com.google.api.services.bigquery.Bigquery; 
import com.google.api.services.bigquery.Bigquery.Datasets; 
import com.google.api.services.bigquery.model.DatasetList; 

import java.io.File; 
import java.io.IOException; 
import java.security.GeneralSecurityException; 


public class BigQueryJavaServiceAccount { 

    private static final String SCOPE = "https://www.googleapis.com/auth/bigquery"; 
    private static final HttpTransport TRANSPORT = new NetHttpTransport(); 
    private static final JsonFactory JSON_FACTORY = new JacksonFactory(); 

    public static void main(String[] args) throws IOException, GeneralSecurityException { 
    GoogleCredential credential = new GoogleCredential.Builder().setTransport(TRANSPORT) 
     .setJsonFactory(JSON_FACTORY) 
     .setServiceAccountId("XXXXXXX@developer.gserviceaccount.com") 
     .setServiceAccountScopes(SCOPE) 
     .setServiceAccountPrivateKeyFromP12File(new File("my_file.p12")) 
     .build(); 

    Bigquery bigquery = Bigquery.builder(TRANSPORT, JSON_FACTORY) 
     .setApplicationName("Google-BigQuery-App/1.0") 
     .setHttpRequestInitializer(credential).build(); 

    Datasets.List datasetRequest = bigquery.datasets().list("publicdata"); 
    DatasetList datasetList = datasetRequest.execute(); 
    System.out.format("%s\n", datasetList.toPrettyString()); 
} 

相同片段：

import httplib2 

from apiclient.discovery import build 
from oauth2client.client import SignedJwtAssertionCredentials 

# REPLACE WITH YOUR Project ID 
PROJECT_ID = 'XXXXXXXXXXX' 
# REPLACE WITH THE SERVICE ACCOUNT EMAIL FROM GOOGLE DEV CONSOLE 
SERVICE_ACCOUNT_EMAIL = 'XXXXX@developer.gserviceaccount.com' 

f = file('key.p12', 'rb') 
key = f.read() 
f.close() 

credentials = SignedJwtAssertionCredentials(
    SERVICE_ACCOUNT_EMAIL, 
    key, 
    scope='https://www.googleapis.com/auth/bigquery') 

http = httplib2.Http() 
http = credentials.authorize(http) 

service = build('bigquery', 'v2') 
datasets = service.datasets() 
response = datasets.list(projectId=PROJECT_ID).execute(http) 

print('Dataset list:\n') 
for dataset in response['datasets']: 
    print("%s\n" % dataset['id'])
