blocks|key|1804974|text|在与同样的问题斗争了几个小时后，我终于找到了解决方案(至少对我的情况是这样)。即使这个帖子是旧的，我还是把它贴在这里，这样其他人以后就可以找到它了。它是这样的：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1804975|#+Get+your+message
message+=+service.users().messages().get(userId=user_id,+id=msg_id,+format='full').execute()

#+Get+the+right+body+data+item+(this+part+was+my+Heureka-moment+as+there+are+several+'data'+keys)
content+=+message['payload']['parts'][0]['parts'][1]['body']['data']

#+Encode
msg_body+=+base64.urlsafe_b64decode(content).decode('utf-8')|code-block|syntax|javascript|1804976|这个序列让我的解码器工作起来了。关于base64和Google+Gmail+API的解码/编码问题，有很多不同的解决方案建议，但似乎每个案例都是不同的。希望这个解决方案也能对你有所帮助！|1804977|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

After hours of struggling with the same problem myself, I finally found the solution (at least for my case). Even through the thread is old, I'm posting it here so that others may find it later. Here it goes:

<pre><code># Get your message
message = service.users().messages().get(userId=user_id, id=msg_id, format='full').execute()

# Get the right body data item (this part was my Heureka-moment as there are several 'data' keys)
content = message['payload']['parts'][0]['parts'][1]['body']['data']

# Encode
msg_body = base64.urlsafe_b64decode(content).decode('utf-8')
</code></pre>

This sequence got the de/encoding working for me. There are as many different solution suggestions out there as there are threads about the decoding/encoding issues with base64 and Google Gmail API but it seems that each case is unique. Hope this solution also helps you!

blocks|key|1785292|text|谢谢塔皮塔皮。Python的Gmail+API文档可能会更清楚一些。上面的解决方案也适用于我。我可以通过以下方式检索内容：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1785293|+msgs+=+message['payload']['parts']

Thanks Tuppitappi. The Gmail API doc for Python could be a bit clearer. The above solutions works for me too. I could retrieve the content the following way:

<pre><code> msgs = message['payload']['parts']
 msg = msgs[1]['body']['data']
</code></pre>

The MessagePart may consist of different parts:

<pre><code>"parts": [
 {
 "partId": "0",
 "mimeType": "text/plain",
 "filename": "",
 "headers": [
 { "name": "Content-type", "value": "text/plain;charset=utf-8" },
 { "name": "Content-Transfer-Encoding", "value": "quoted-printable" }
 ],
 "body": {
 "size": 1887,
 "data": "ascii string to be decoded"
 }
 },
 {
 "partId": "1",
 "mimeType": "text/html",
 "filename": "",
 "headers": [
 { "name": "Content-type", "value": "text/html;charset=utf-8" },
 { "name": "Content-Transfer-Encoding", "value": "quoted-printable" }
 ],
 "body": {
 "size": 66970,
 "data": "longer ascii string to be decoded"
 }
 }
 ]
</code></pre>

Extract from the <a href="https://developers.google.com/gmail/api/v1/reference/users/messages" rel="nofollow noreferrer">Doc</a> for the full payload:

<pre><code>Resource representations An email message.

{ "id": string, "threadId": string, "labelIds": [
 string ], "snippet": string, "historyId": unsigned long, "internalDate": long, "payload": {
 "partId": string,
 "mimeType": string,
 "filename": string,
 "headers": [
 {
 "name": string,
 "value": string
 }
 ],
 "body": users.messages.attachments Resource,
 "parts": [
 (MessagePart)
 ] }, "sizeEstimate": integer, "raw": bytes }
</code></pre>

I have a problem. I am trying to read emails from gmail using the gmail api. I followed the instructions from here <a href="https://developers.google.com/gmail/api/v1/reference/users/messages/get" rel="nofollow noreferrer">https://developers.google.com/gmail/api/v1/reference/users/messages/get</a>

I made a few changes to run it on python 3, so I ended up with the following code:

<pre><code>def GetMimeMessage(service, user_id, msg_id):
try:
 message = service.users().messages().get(userId=user_id, id=msg_id,
 format='raw').execute()

 print ('Message snippet: %s' % message['snippet'])
 msg_str = base64.urlsafe_b64decode(message['raw'].encode('utf8'))
 mime_msg = email.message_from_bytes(msg_str)
 print(mime_msg)

 return mime_msg
except errors.HttpError as error:
 print ('An error occurred: %s' % error)
</code></pre>

Now the output is very close to what I would love to have, but there is a problem that the Hungarian accented characters in the output are weird:
<code>G=C3=A1bor</code> instead of <code>Gábor</code>

And also the html tags are kind broken:

<pre><code>Follow us: =09=09=09=09=09=09=09=09=09&lt;a href=3D"http=
</code></pre>

I have already figured out that this is related to fact how the message is encoded, see header of the email:

<pre><code>Content-Type: text/html; charset=UTF-8
Content-Transfer-Encoding: quoted-printable
</code></pre>

The problem is, that I can't seem to find a way to decode it properly. Ever help is appreciated.

Gmail api python encode/decode error

Python

我有个问题。我正在尝试使用gmail api读取来自gmail的电子邮件。我按照这里的指示去做了我做了一些修改，以便在python 3上运行它，所以我最终使用了以下代码：def GetMimeMessage(service, user_id, msg_id):try:  message = service.users(...
