我尝试使用服务帐户在JUnit测试中简单地从gmail发送电子邮件。
我有这个测试：
@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...
}
这失败了：
Scopes are https://www.googleapis.com/auth/gmail.compose

我的文件src/test/resources/myProject.json包含以下信息：
{
"type": "service_account",
"project_id": "xxxxxxxxxxx",
"private_key_id": "28341330...",
"private_key": "-----BEGIN PRIVATE KEY-----\.........\n-----END PRIVATE KEY-----\n",

}
如何排除造成这种愚蠢行为的原因，而不是Google提供的有效的失败保护措施？
答案 0 :(得分：0)
您可以从此处获得解决问题的完整程序：
Gmail REST API : 400 Bad Request + Failed Precondition
对于400个不良请求，我给出了答案。你可以通过这个。
