当section设置为1.2时，PHP imap_fetchbody（）函数不会返回

Question

背景

我正在运行以下代码以使用IMAP PHP extension检索电子邮件：

#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/in.h>
#include <netdb.h>
#include <stdio.h>
#include <unistd.h>
#include <stdlib.h> /* for atoi */

char *msg = "Very long message";
void error(char *msg)
{
perror(msg);
exit(0);
}

int main(int argc, char *argv[])
{
int sock, n;
unsigned short port;
struct sockaddr_in server;
struct hostent *hp;
char buffer[1024];

if (argc != 3) { 
     printf("Usage: %s server port\n", argv[0]);
     exit(1);
}
sock= socket(AF_INET, SOCK_STREAM, 0);
if (sock < 0) error("Opening socket");

server.sin_family = AF_INET;
hp = gethostbyname(argv[1]);
if (hp==NULL) error("Unknown host");
memcpy((char *)&server.sin_addr,(char *)hp->h_addr,         
      hp->h_length);
port = (unsigned short)atoi(argv[2]);
server.sin_port = htons(port);
if (connect(sock, (struct sockaddr *)&server, sizeof server) < 0)
         error("Connecting");
n = send(sock, msg, strlen(msg),0);
printf("sent %d bytes\n", n);
if (n < strlen(msg))
         error("Writing to socket");

n = recv(sock, buffer, 1023,0);
if (n < 1) error("reading from socket");
buffer[n]='\0';
printf("The message from the server is %s\n",buffer);
if (close(sock) < 0) error("closing");
printf("Client terminating\n");

return 0;
}

问题

将<?php /* connect to gmail */ $hostname = '{imap.gmail.com:993/imap/ssl}INBOX'; $username = 'blah@gmail.com'; $password = 'blah'; $inbox = imap_open($hostname,$username,$password); $emails = imap_search($inbox,'ALL'); if ($emails) { foreach($emails as $emailNumber) { $overview = imap_fetch_overview($inbox,$emailNumber,0); $message = imap_fetchbody($inbox,$emailNumber,"1"); echo $overview[0]->from; echo $message; } } imap_close($inbox); ?> imap_fetchbody()参数设置为section后，我会收到包含标题和HTML的完整电子邮件。 http://pastebin.com/np84rG7r

但是，当将参数更改为1以便将消息标识为HTML时，它不会返回任何内容。

为什么会这样？

更新

我已经制作了一小段代码来手动完成工作，直到我找到它无法正常工作的原因：

1.2

不幸的是，imap_fetchbody的部件号取决于您的邮件是否带有html，以及是否带有附件。当您收到纯文本邮件时，则需要使用1而不是1.2。

要阅读完整的悲剧，我建议https://www.php.net/manual/en/function.imap-fetchbody.php#89002

确保您始终获得体内含量的一种俗气的方法是

$message = imap_fetchbody($inbox,$emailNumber,1.2);
if(empty($bodyText)){
    $message = imap_fetchbody($inbox,$emailNumber,1);
}
