之前测试功能写过一次，因为代码忘记保存，导致真正用到的时候怎么也想不起来当初怎么写的了，复现后还是写个文章记录一下，省的下次再忘记。
php后端
/**
* 图片保存到本地
*/
public function uploadLocalImage()
{
try {
$img = $this->_request->file('img');
if (empty($img)) {
throw new \Exception('缺少图片参数');
}
$writeDir = "images/".date('Ymd');
$dir = "D:/phpstudy_pro/WWW/vkm_locarun_dist/dist/".$writeDir;
//$dir = "local_run/" . date('Ymd'); //linux调试地址
if (!file_exists($dir)) {
mkdir($dir, 0777, true);
}
$extension = substr($img->getMimeType(), -3);
if ($extension == 'bmp') {
$fileName = UtilService::createOrderNo() . '.bmp';
}if ($extension == 'png') {
$fileName = UtilService::createOrderNo() . '.png';
}else{
$fileName = UtilService::createOrderNo() . '.jpg';
}
$imgContent = file_get_contents($img);
file_put_contents($dir . '/' . $fileName, $imgContent);
$localhostImg = env('CLIENT_URL') . $writeDir . '/' . $fileName;
//http://127.0.0.1:8000/xxx/20231016/xxx.jpg 读取方式
$this->returnSuccess($localhostImg);
} catch (\Exception $e) {
$this->returnFault($e->getMessage());
}
}

WWWForm form = new WWWForm();

//最后一个参数是图片的mimeType, 因为上传的图片有jpg、png、bmp几种格式，此处取文件后缀和image组合字符串作为mimeType
form.AddBinaryData("img", fileByte, Path.GetFileName(filePath), $"image/{
Path.GetExtension(filePath)}");
Helper.Log($"{

搞定。
