以下示例使用 cURL 上传包含为二进制文件的图像文件.

The example below uses cURL to upload image file included as a binary file.

curl -i --upload-file /path/to/image.png --header "Authorization: Token" 'url....'

它工作正常.我需要从我的 Java 应用程序发出这个请求.

It works fine. I need to make this request from my Java application.

我已经尝试了下一个代码

I have tried next code

URL image_url = Thread.currentThread().getContextClassLoader().getResource("jobs_image.jpg"); String path = image_url.getFile(); HttpResponse<String> response = Unirest.post(uploadUrl) .header("cache-control", "no-cache") .header("X-Restli-Protocol-Version", "2.0.0") .header("Authorization", "Bearer " + token + "") .field("file", new File(path)) .asString();

但是，它返回状态 400 Bad Request.有没有办法从Java调用这样的请求?

However, it returns status 400 Bad Request. Is there any way to call such request from Java?
