请求执行失败: https://apps-apis.google.com/a/feeds/emailsettings/2.0/imap.google.com/Providentinnovation Test/imap
请参见以下代码快照:
when i tring to update the imap using the UpdateImap method. retirn to me this error :
GDataRequestException was unhandled
Execution of request failed: https://apps-apis.google.com/a/feeds/emailsettings/2.0/imap.google.com/Providentinnovation Test/imap
see the below code snapshot:
domain = "www.gmail.com";
adminEmail = "myemail@gmail.com";
adminPassword = "********";
testUserName = "myemail@gmail.com";
GoogleMailSettingsService service = new GoogleMailSettingsServic(domain, "apps-demo");
service.setUserCredentials(adminEmail, adminPassword);
service.UpdateImap(testUserName, "true");
我收到以下错误:未处理GDataRequestException
i got the below error : GDataRequestException was unhandled
推荐答案
首先确保这正是您要制作的东西? IMAP将电子邮件副本下载到本地计算机，因为POP3可以直接从服务器访问电子邮件.
因此，如果您要开发电子邮件客户端(例如Outlook或Thunderbird)，则IMAP是一个不错的选择.在这种情况下，您需要处理将保存在计算机上，然后更新到邮件服务器的电子邮件文件.
如果您只想阅读/发送电子邮件，则应使用POP3.
***********
此外，请确保在您的GMAIL设置中启用了电子邮件转发选项***********
对于POP3，此代码有效:
Hi,
1st make sure that this exactly what you want to make? IMAP download the copy of emails to local machine where as POP3 provides access to emails directly from server.
So if you are trying to develop a email client like outlook or thunderbird IMAP is a good option. in that case you need to handle email files which will be saved on your computer and then updated to your mail server.
if you simply wants to read/send emails you should use POP3.
***********
ALSO MAKE SURE THAT EMAIL FORWARDING OPTION IS ENABLED IN YOUR GMAIL SETTING ***********
For POP3 This code will work:

using System.Collections.Specialized;
using System.Configuration;

感谢您的重播.
但是我需要使用IMAP4协议，即通过使用Google API从代码启用imap的问题
thanks for your replay.
but i need to work with IMAP4 protocol , the problem with enabling the imap from the code by using google API
这篇关于尝试使用GoogleMailSettingsService类imapupdate启用IMAP时出现错误的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
