我试图使用WinHttpRequest上传文件，但它不工作。
我做的一个cordova应用程序中的PHP文件正在工作。
我不知道还能做什么。
任何人都可以帮助。
谢谢。
VFP代码。
filecontent = FileToStr(ficheiro)
loHTTP = CREATEOBJECT("WinHttp.WinHttpRequest.5.1")
loHTTP.Open("POST", "http://-----.com/webspace/upload.php", .F.)
loHTTP.SetRequestHeader("content-type", "text/plain")
varrequest = 'attachment; filename="' + JUSTFNAME(ficheiro) + '"'
loHTTP.SetRequestHeader("content-disposition", varrequest)
loHTTP.Send(filecontent)
WAIT WINDOW loHTTP.status
upload.php中的代码。
<?php
$uploaddir = 'upload/';
$uploadfile = $uploaddir . $_FILES['file']['name'];
if (move_uploaded_file($_FILES['file']['tmp_name'], $uploadfile)) {
echo "File successfully uploaded.\n";
}
＆gt;
PHP错误。
[12-Dec-2018 12:28:02 UTC] PHP Notice: Undefined index: file in /home/webspace/upload.php on line 3
[12-Dec-2018 12:28:02 UTC] PHP Notice: Undefined index: file in /home/webspace/upload.php on line 5
我修改了代码，现在我得到的文件是 "HTTP_RAW_POST_DATA"，当我在PHP中做一个var_dump的时候
当前代码。
loHTTP = CREATEOBJECT("WinHttp.WinHttpRequest.5.1")
loHTTP.Open("POST", "http://www.----------.com/webspace/getfile.php", .F.)
xBOUNDARY = "+++++"
vbCrLf = CHR(10) + CHR(13)
filecontent = "--" + xBOUNDARY + vbCrLf
filecontent = filecontent + 'Content-Disposition: form-data; name="file"; filename="' + JUSTFNAME(ficheiro) + '"' + vbCrLf
filecontent = filecontent + "Content-type: text/plain" + vbCrLf + vbCrLf
filecontent = filecontent + FileToStr(ficheiro)
filecontent = filecontent + vbCrLf
filecontent = filecontent + "--" + xBOUNDARY + "--"
filecontent = filecontent + vbCrLf
loHTTP.SetRequestHeader("CONTENT_TYPE", "multipart/form-data; boundary=" + xBOUNDARY + vbCrLf)
loHTTP.SetRequestHeader("CONTENT_NAME", JUSTFNAME(ficheiro) + vbCrLf)
loHTTP.Send(filecontent)
在PHP中的var_dump。
