我正在尝试将空格键发送到应用程序而不先激活它.以下代码几乎可以实现我想要的功能,但它首先将应用程序带到前台.

tell application "X"
    activate
    tell application "System Events" to key code 49
end tell

这两个步骤是否必须删除模型？

var model = collection.get(id);
model.destroy();
collection.remove(model);

当从模型中删除模型时,是否有办法销毁模型？

如何指定multipart/form-data请求的特定部分的内容类型？图像的内容类型正在发送application/octet-stream,但服务器期望它image/jpeg.这会导致服务器拒绝我的请求.

$data["file"] = "@/image.jpg";
$data["title"] = "The title";
$data["description"] = "The description";

//make the POST request
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL,$url);
curl_setopt($curl, CURLOPT_VERBOSE, 1);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_HTTPHEADER, $header);
curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
$result = curl_exec($curl);

这是请求的相关部分:

Content-Type: multipart/form-data; boundary=----------------------------fc57f743c490

------------------------------fc57f743c490
Content-Disposition: form-data; name="file"; filename="NASA-23.jpg"
Content-Type: application/octet-stream

我希望它是:

Content-Type: multipart/form-data; boundary=----------------------------fc57f743c490

------------------------------fc57f743c490
Content-Disposition: form-data; name="file"; filename="NASA-23.jpg"
Content-Type: image/jpeg
