我在使用Gmail PHP API时遇到了问题

我想检索电子邮件的正文内容，但我只能检索带有附件的电子邮件！我的问题是为什么

以下是我目前的代码：

// Authentication things above...
$client = getClient();
$gmail = new Google_Service_Gmail($client);    
$list = $gmail->users_messages->listUsersMessages('me', ['maxResults' => 1000]);

while ($list->getMessages() != null) {   
    foreach ($list->getMessages() as $mlist) {               
        $message_id = $mlist->id;   
        $optParamsGet2['format'] = 'full';
        $single_message = $gmail->users_messages->get('me', $message_id, $optParamsGet2);

        $threadId = $single_message->getThreadId();
        $payload = $single_message->getPayload();
        $headers = $payload->getHeaders();
        $parts = $payload->getParts();
        //print_r($parts); PRINTS SOMETHING ONLY IF I HAVE ATTACHMENTS...
        $body = $parts[0]['body'];
        $rawData = $body->data;
        $sanitizedData = strtr($rawData,'-_', '+/');
        $decodedMessage = base64_decode($sanitizedData); //should display my body content
    }

    if ($list->getNextPageToken() != null) {
        $pageToken = $list->getNextPageToken();
        $list = $gmail->users_messages->listUsersMessages('me', ['pageToken' => $pageToken, 'maxResults' => 1000]);
    } else {
        break;
    }
}

我知道的第二种检索内容的方法是使用标题部分中的代码段，但它只检索前50个左右的字符，这不是很有用。
让我们做一个小实验。我给自己发了两条信息。一个有附件，一个没有

这些响应对应于代码中的
$parts
。正如您所见，如果您幸运的话，
$parts[0]['body']->数据将为您提供所需，但大多数情况下不会通常有两种方法来解决这个问题。您可以实现以下算法（您在PHP方面比我好得多，但这是它的概述）：遍历payload.parts ，检查它是否包含一个part ，该part具有您要查找的正文（或者text/plain 或者text/html ）。如果有，您就完成了搜索。如果你正在解析一封没有附件的邮件，这就足够了再次执行步骤1，但这一次使用您刚刚检查的部分中的部分，递归执行。您最终将找到您的零件。如果您正在解析一封带有附件的邮件，这将最终找到您的正文该算法可能类似于以下内容（JavaScript中的示例）： var响应={ “有效载荷”：{ “部分”：[ { “mimeType”：“多部分/备选方案”， “文件名”：“， “标题”：[ { “名称”：“内容类型”， “值”：“多部分/备选方案；边界=001a1142e23c551e8e05200b4be0” } ], “正文”：{ “大小”：0 }, “部分”：[ { “partId”：“0.0”， “mimeType”：“文本/普通”， “文件名”：“， “标题”：[ { “名称”：“内容类型”， “值”：“文本/纯文本；字符集=UTF-8” } ], “正文”：{ “尺寸”：9， “数据”：“V293IG1hbg0K” } }, { “partId”：“0.1”， “mimeType”：“text/html”， “文件名”：“， “标题”：[ { “名称”：“内容类型”， “值”：“text/html；charset=UTF-8” } ], “正文”：{ “尺寸”：30， “数据”：“PGRpdiBkaXI9Imx0ciI-V293IG1hbjwvZGl2Pg0K” } } ] }, { “partId”：“1”， “mimeType”：“图像/jpeg”， “文件名”：“feelthebern.jpg”， “标题”：[ { “名称”：“内容类型”， “值”：“image/jpeg；name=\“feelthebern.jpg” }, { “名称”：“内容处置”， “值”：“附件；文件名=\”feelthebern.jpg“” }, { “名称”：“内容传输编码”， “值”：“base64” }, { “名称”：“X-附件-Id”， “值”：“f_ieq3ev0i0” } ], “正文”：{ “附件”是一个附件：“附件”是一个附件，它是一个附件，它是一个附件，一个附件，一个附件，一个附件，一个附件，一个附件，一个附件，一个附件，一个附件，一个附件，一个附件，一个附件，一个附件，一个附件，一个附件，一个附件，一个附件，一个附件，一个附件，一个附件，一个附件，一个附件，一个附件，一个附件，一个附件，一个附件，一个附件，一个附件，一个附件，一个附件，一个附件，一个附件，一个附件，一个附件，一个附件，一个附件，一个附件，一个附件，一个附件，一个附件，一个附件，一个附件，一个附件，一个附件，一个，一个附件，一个附件，一个附件，一个，一个附件，一个附件，一个，一个，一个，一个，一个，一5计量单位“， “尺寸”：100446 } } ] } }; //例如，在纯文本消息中，有效负载是唯一的部分。 var parts=[response.payload]； while（零件长度）{ var part=parts.shift（）；如果（部分，部分）{ 零件=零件-混凝土（零件-零件）； } 如果（part.mimeType==='text/html'）{ var decodedPart=decodeURIComponent（escape（atob（part.body.data.replace（/\-/g，'+'））.replace（/\\-/g，'/'）））； console.log（解码部分）； } } 更新：您可能想查看下面我的第二个答案，以获得更完整的代码。最后，我今天终于工作了，下面是找到尸体的完整代码答案——多亏了@Tholle： // Authentication things above /* * Decode the body. * @param : encoded body - or null * @return : the body if found, else FALSE; */ function decodeBody($body) { $rawData = $body; $sanitizedData = strtr($rawData,'-_', '+/'); $decodedMessage = base64_decode($sanitizedData); if(!$decodedMessage){ $decodedMessage = FALSE; } return $decodedMessage; } $client = getClient(); $gmail = new Google_Service_Gmail($client); $list = $gmail->users_messages->listUsersMessages('me', ['maxResults' => 1000]); try{ while ($list->getMessages() != null) { foreach ($list->getMessages() as $mlist) { $message_id = $mlist->id; $optParamsGet2['format'] = 'full'; $single_message = $gmail->users_messages->get('me', $message_id, $optParamsGet2); $payload = $single_message->getPayload(); // With no attachment, the payload might be directly in the body, encoded. $body = $payload->getBody(); $FOUND_BODY = decodeBody($body['data']); // If we didn't find a body, let's look for the parts if(!$FOUND_BODY) { $parts = $payload->getParts(); foreach ($parts as $part) { if($part['body']) { $FOUND_BODY = decodeBody($part['body']->data); break; } // Last try: if we didn't find the body in the first parts, // let's loop into the parts of the parts (as @Tholle suggested). if($part['parts'] && !$FOUND_BODY) { foreach ($part['parts'] as $p) { // replace 'text/html' by 'text/plain' if you prefer if($p['mimeType'] === 'text/html' && $p['body']) { $FOUND_BODY = decodeBody($p['body']->data); break; } } } if($FOUND_BODY) { break; } } } // Finally, print the message ID and the body print_r($message_id .
