使用 Ssl = true 时，Chilkat Upload BeginUpdate 失败并显示 "Failed to read TLS record (2)"

Question

我的主机更新了一些关于我的服务器的东西，我猜是 php 版本，从那时起，我的 php 上传脚本不再适用于 Chilkat.Upload。

    Dim _Chil As New Chilkat.Upload
    _Chil.Ssl = True

    _Chil.Hostname = "www.example.com"
    _Chil.Path = "/upload.php"
    _Chil.AddFileReference("file", "D:\test.txt")

    Dim bUploadStarted As Boolean = _Chil.BeginUpload()

    If Not bUploadStarted Then
        MessageBox.Show("Error trying to BeginUpload: " & _Chil.LastErrorText)
        Return
    End If

    Do While _Chil.UploadInProgress
        _Chil.SleepMs(200)
    Loop

    Dim bSuccess As Boolean = _Chil.UploadSuccess
    If Not bSuccess Then
        MessageBox.Show("Error uploading:" & _Chil.LastErrorText)
    Else
        MessageBox.Show("Upload succeeeded. :-)") 
    End If

使用 .Ssl = true , BeginUpload 失败。这是最后一个错误文本：

如果我删除 .Ssl = true，则 BeginUpload 成功，但 UploadSuccess return false。最后的错误文本是：

ChilkatLog:
  BeginUpload:
    DllDate: Aug 28 2021
    ChilkatVersion: 9.5.0.88
    UnlockPrefix: NONE

    usingTls: 0
    Connecting directly to HTTP server
    domain: www.example.com
    port: 80
  --BeginUpload

如果我通过浏览器运行脚本，它工作正常。

这是我的代码：

myform.php:

<center>
    <form action="upload.php" method="post" enctype="multipart/form-data">
   <input type="file" name="file" >
   <input type="submit" name="upload" value="upload file">
 </form>
</center>

upload.php:

<?php
    move_uploaded_file($_FILES["file"]["tmp_name"], "uploads/" . $_FILES["file"]["name"]);
?>

Answer 1

HTTPS 使用端口 443。

所以使用

_Chil.Port = 443

解决了问题。

使用 Ssl = true 时，Chilkat Upload BeginUpdate 失败并显示 "Failed to read TLS record (2)"

Chilkat Upload BeginUpdate fails with "Failed to read TLS record (2)" when using Ssl = true
