[PHP] MIME邮件协议的multipart类型
邮件协议中的三种情况,对应下面的三种类型
multipart/mixed可以包含附件。
multipart/related可以包含内嵌资源。
multipart/alternative 纯文本与超文本共存
1.纯文本的,只需要一块content-type块,不需要multipart块
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 | Date: Tue, 16 Apr 2019 17:35:19 +0800Received: from shihan2@sopans.com([]) by via HTTP; Tue, 16 Apr 2019 17:35:19 +0800 (CST)Reply-To: shihan2@sopans.comFrom: <shihan2@sopans.com>To: shihan2@sopans.comSubject: =?GBK?B?ztLAtLLiytQ=?=MIME-Version: 1.0X-Priority: 3X-MessageID: 1555407319.5028.10108X-Originating-IP: []X-Mailer: Sina WebMail 4.0X-Sina-Mid: 044D8EB6F6EF3F6FAE1A32D8B0930F609000000000000002Content-Type: text/plain; charset=GBKContent-Transfer-Encoding: base64aGVsbG8= |
2.内容是html的要加两块content-type块内容,一块是html一块是纯文本,并且要增加一块multipart类型块

3.有附件的话,还会增加下面两种multipart类型
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 | Date: Tue, 16 Apr 2019 17:38:47 +0800Received: from shihan2@sopans.com([]) by via HTTP; Tue, 16 Apr 2019 17:38:47 +0800 (CST)Reply-To: shihan2@sopans.comFrom: <shihan2@sopans.com>To: shihan2@sopans.comSubject: =?GBK?B?ztLAtLLiytQ=?=MIME-Version: 1.0X-Priority: 3X-MessageID: 1555407527.4947.4232X-Originating-IP: []X-Mailer: Sina WebMail 4.0X-Sina-Mid: 044D8EB6F6EF3F6FAE1A32D8B0930F609000000000000002Content-Type: multipart/mixed; boundary="=-sinamail_mix_fe895d50cd0d0669bb8a7eb8c697db19"--=-sinamail_mix_fe895d50cd0d0669bb8a7eb8c697db19Content-Type: multipart/alternative; boundary="=-sinamail_alt_f50efff67f5369967ea1a6c77020a1e7"--=-sinamail_alt_f50efff67f5369967ea1a6c77020a1e7Content-Type: text/plain; charset=GBKContent-Transfer-Encoding: base64Content-Disposition: inlineaGVsbG8=--=-sinamail_alt_f50efff67f5369967ea1a6c77020a1e7Content-Type: text/html; charset=GBKContent-Transfer-Encoding: base64Content-Disposition: inlinePGgxPmhlbGxvPC9oMT4=--=-sinamail_alt_f50efff67f5369967ea1a6c77020a1e7----=-sinamail_mix_fe895d50cd0d0669bb8a7eb8c697db19Content-Type: application/octet-stream; name="=?GBK?B?MS5sb2c=?="Content-Disposition: attachment; filename="=?GBK?B?MS5sb2c=?="Content-Transfer-Encoding: base64MXwyNTAgUElQRUxJTklORw0K--=-sinamail_mix_fe895d50cd0d0669bb8a7eb8c697db19-- |
