Question

在项目中，我正在为一家公司工作，我需要将一个图像发送到服务器上的.php，然后将其保存在一个文件夹中，然后发送回来，这样我就可以将它保存在一个桌子上了。 DB。该公司希望我发送原始图像而不是将其转换为base64，发送它并在.php文件上解码

我的问题是，这可能吗？如果是的话，我该怎么做？

感谢您的帮助。

是的，这是可能的。

检查你的php.ini并确保这一行是这样的：

file_uploads = On

创建html表单：

<!DOCTYPE html>
<html>
<body>

<form action="upload.php" method="post" enctype="multipart/form-data">
    Select image to upload:
    <input type="file" name="fileToUpload" id="fileToUpload">
    <input type="submit" value="Upload Image" name="submit">
</form>

</body>
</html>

创建upload.php文件：

<?php
$target_dir = "uploads/";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$uploadOk = 1;
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
// Check if image file is a actual image or fake image
if(isset($_POST["submit"])) {
    $check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
    if($check !== false) {
        echo "File is an image - " . $check["mime"] . ".";
        $uploadOk = 1;
    } else {
        echo "File is not an image.";
        $uploadOk = 0;
    }
}
// Check if file already exists
if (file_exists($target_file)) {
    echo "Sorry, file already exists.";
    $uploadOk = 0;
}
// Check file size
if ($_FILES["fileToUpload"]["size"] > 500000) {
    echo "Sorry, your file is too large.";
    $uploadOk = 0;
}
// Allow certain file formats
if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg"
&& $imageFileType != "gif" ) {
    echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";
    $uploadOk = 0;
}
// Check if $uploadOk is set to 0 by an error
if ($uploadOk == 0) {
    echo "Sorry, your file was not uploaded.";
// if everything is ok, try to upload file
} else {
    if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) {
    echo "The file ". basename( $_FILES["fileToUpload"]["name"]). " has been     uploaded.";
    } else {
        echo "Sorry, there was an error uploading your file.";
    }
}
?>

为了确保一切正常，请创建一个名为uploads的文件夹，并确保文件权限和所有权都可以。

希望它对你有所帮助。

不使用Base64直接将图像发送到.PHP
