好的 - 这是我之前关于使用 php 脚本发送电子邮件的问题的延续。我现在使用PEAR发送邮件。我使用的php脚本如下（单独执行成功）：PHPEMail.php
<?php
require_once "Mail.php"; // Pear Mail.php
$from = "FromName <FromName@SomeAddress.com>";
$to = $_POST["destination"]; // destination
$subject = "Hello You!";
$body = $_POST["nicebody"]; // body of text sent
$host = "ValidServerName";
$username = "User"; // validation at server
$password = "Password"; // validation at server
$headers = array ('From' => $from,
'To' => $to,
'Subject' => $subject);
$smtp = Mail::factory('smtp',
array ('host' => $host,
'auth' => true,
'username' => $username,
'password' => $password));
$mail = $smtp->send($to, $headers, $body);
if (PEAR::isError($mail)) {
echo("<p>" . $mail->getMessage() . "</p>");
} else {
echo("<p>Message successfully sent!</p>");
}
?>
我现在需要从 Delphi 执行这个脚本 (PHPEMail.php)，传递一些变量，使用 winsock。我要使用这段代码 - 到目前为止还没有成功：
Procedure SendEmail;
var
WSADat:WSAData;
SomeText:TextFile;
Client:TSocket;
Info,TheData,Lina,Nicebody:String;
SockAddrIn:SockAddr_In;
begin
try
if not FileExists(Log) then exit;
AssignFile(SomeText, Log); // try to open log, assigned to SomeText
Reset(SomeText); // Reopen SomeText for reading
while not Eof(SomeText) do
begin
ReadLn(SomeText, Lina); //read each line of SomeTextans place it in linha
nicebody:=Nicebody+#13#10+Lina; // nicebody = all line red from SomeText
end;
CloseFile(SomeText); // SomeText is closed
DeleteFile(PChar(Log)); // log is deleted
//
WSAStartUp(257,WSADat);
Client:=Socket(AF_INET,SOCK_STREAM,IPPROTO_IP);
SockAddrIn.sin_family:=AF_INET;
SockAddrIn.sin_port:=htons(80);
SockAddrIn.sin_addr.S_addr:=inet_addr('66.66.66.66'); // server IP
if Connect(Client,SockAddrIn,SizeOf(SockAddrIn))=0 then begin
Info:='destination='+EmailDestAddressFromIni + '' +'Nicebody='+Nicebody;
TheData:='POST PHPEMail.php HTTP/1.0' +#13#10+
'Connection: close' +#13#10+
'Content-Type: application/x-www-form-urlencoded'+#13#10+
'Content-Length: '+IntToStr(Length(Info)) +#13#10+
'Host: someEmailHostAddress' +#13#10+
'Accept: text/html' +#13#10+#13#10+
Info +#13#10;
Send(Client,Pointer(TheData)^,Length(TheData),0);
end;
CloseSocket(Client);
except
exit;
end;
end;

我很确定故障出在发送到 Web 服务器的“TheData”中。PHP脚本只是没有被触发。有人知道出了什么问题吗？
（注意：我想用winsock，我不想要第三方组件。完整的代码，它是一个服务器，重约12ko，注定要嵌入一些硬件中）。
见最后的代码。
因为我在服务器日志上看不到 POST，所以我对我的代码做了一些改进（加上一些错误消息）。现在服务器的日志显示发送的数据包的一些跟踪......也就是说，通常的 id 和时间加上字母“P”......可能是单词 'POST' 的第一个字母（发送的数据）。因此，我必须调查“Send()”命令。（我在德尔福 2009 年）。我没有从 winsock 或发送命令中得到任何错误。
Procedure SendEmail;

end;

DeleteFile(PChar(Log)); // delete log
// Initialize Winsock
i_result := WSAStartUp(257,WSAData);
if (i_Result <> NO_ERROR) then
begin
MessageBox(0,'Initialization of winsock failed.','Error',MB_OK Or MB_ICONERROR);
Exit;
end;
// Create a SOCKET for connecting to server

等待 POST 的 pearemail.php 脚本：
<?php
require_once "Mail.php";
$from = "name <name@tatata.com>";
$to = $_POST["destination"];
$subject = "Number 2!";
$body = $_POST["contenu"];
$host = "mail.server.com";
$username = "user";
$password = "password";
$headers = array ('From' => $from,
'To' => $to,
'Subject' => $subject);
$smtp = Mail::factory('smtp',
array ('host' => $host,
'auth' => true,
'username' => $username,
'password' => $password));
$mail = $smtp->send($to, $headers, $body);
if (PEAR::isError($mail)) {
echo("<p>" . $mail->getMessage() . "</p>");
} else {
echo("<p>Message successfully sent!</p>");
}
?>
