I am trying to just send an email from gmail in a JUnit test using a service account.
I have this test:
@Test public void testGmailCredential() throws GeneralSecurityException, URISyntaxException { try { InputStream is = getClass().getClassLoader().getResourceAsStream("myProject.json"); GoogleCredential credential = GoogleCredential.fromStream(is).createScoped(GmailScopes.all()); System.out.println("Scopes are " + credential.getServiceAccountScopesAsString()); Gmail gmailService = new Gmail.Builder(getHttpTransport(), JSON_FACTORY, credential) .setApplicationName("WHAT SHOULD THIS VALUE BE?") //.setHttpRequestInitializer(credential) .build(); InternetAddress to = new InternetAddress(" myemail@myurl.com ", "Tom Catfish"); InternetAddress from = new InternetAddress(" myServiceAccountId@xxxxxxxxxx.iam.gserviceaccount.com ", "Some Name"); Properties props = new Properties(); Session session = Session.getDefaultInstance(props, null); MimeMessage email = new MimeMessage(session); email.setFrom(from); email.addRecipient(javax.mail.Message.RecipientType.TO, to); email.setSubject("Subject here"); email.setText("body here"); ByteArrayOutputStream buffer = new ByteArrayOutputStream(); email.writeTo(buffer); byte[] bytes = buffer.toByteArray(); String encodedEmail = Base64.getUrlEncoder().encodeToString(bytes); Message message = new Message(); message.setRaw(encodedEmail); message = gmailService.users().messages().send("me", message).execute(); System.out.println("Message id: " + message.getId()); System.out.println(message.toPrettyString()); // other code... }
What fails with this:
Scopes are https://www.googleapis.com/auth/gmail.compose com.google.api.client.googleapis.json.GoogleJsonResponseException: 400 Bad Request { "code" : 400, "errors" : [ { "domain" : "global", "message" : "Bad Request", "reason" : "failedPrecondition" } ], "message" : "Bad Request" } at com.google.api.client.googleapis.json.GoogleJsonResponseException.from(GoogleJsonResponseException.java:145) at com.google.api.client.googleapis.services.json.AbstractGoogleJsonClientRequest.newExceptionOnError(AbstractGoogleJsonClientRequest.java:113) at com.google.api.client.googleapis.services.json.AbstractGoogleJsonClientRequest.newExceptionOnError(AbstractGoogleJsonClientRequest.java:40) at com.google.api.client.googleapis.services.AbstractGoogleClientRequest$1.interceptResponse(AbstractGoogleClientRequest.java:321) at com.google.api.client.http.HttpRequest.execute(HttpRequest.java:1056) at com.google.api.client.googleapis.services.AbstractGoogleClientRequest.executeUnparsed(AbstractGoogleClientRequest.java:419) at com.google.api.client.googleapis.services.AbstractGoogleClientRequest.executeUnparsed(AbstractGoogleClientRequest.java:352) at com.google.api.client.googleapis.services.AbstractGoogleClientRequest.execute(AbstractGoogleClientRequest.java:469) at com.op.services.NotificationServiceTest.testGmailCredential(NotificationServiceTest.java:90) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:497) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:50) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:12) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:47) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:17) at org.junit.runners.ParentRunner.runLeaf(ParentRunner.java:325) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:78) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:57) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:290) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:71) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:288) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:58) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:268) at org.junit.runners.ParentRunner.run(ParentRunner.java:363) at org.eclipse.jdt.internal.junit4.runner.JUnit4TestReference.run(JUnit4TestReference.java:86) at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:459) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:675) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:382) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:192)
I have a src/test/resources/myProject.json that contains this information:
{ "type": "service_account", "project_id": "xxxxxxxxxxx", "private_key_id": "28341330...", "private_key": "-----BEGIN PRIVATE KEY-----\.........\n-----END PRIVATE KEY-----\n", "client_email": " myServiceAccountId@xxxxxxxxxx.iam.gserviceaccount.com ", "client_id": "1182....", "auth_uri": "https://accounts.google.com/o/oauth2/auth", "token_uri": "https://accounts.google.com/o/oauth2/token", "auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs", "client_x509_cert_url": "https://www.googleapis.com/robot/v1/metadata/x509/myApp%40xxxxxxx.iam.gserviceaccount.com" }
How can I address the cause of this stupid rather than useful failPrecondition resopnse from Google?
