文件上传客户端

   public class FileUploaderClient {

    public static void main(String[] args) {

        // the file we want to upload
        File inFile = new File("C://Users//BallZaR5R5//Desktop//nanana.docx");
        System.out.println(inFile.getAbsolutePath());
        FileInputStream fis = null;
        try {
            fis = new FileInputStream(inFile.getAbsolutePath());

             CloseableHttpClient httpclient = HttpClientBuilder.create().build();   

            // server back-end URL
            HttpPost httppost = new HttpPost("https://box.one.th/app/api/upload ");
            MultipartEntityBuilder builder = MultipartEntityBuilder.create(); 


            // set the file input stream and file name as arguments
            builder.addPart("file", new InputStreamBody(fis, inFile.getName()));
            HttpEntity entity = builder.build();
            httppost.setHeader(HttpHeaders.AUTHORIZATION,  "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9");
            httppost.setEntity(entity);


            // execute the request
            HttpResponse response = httpclient.execute(httppost);

            int statusCode = response.getStatusLine().getStatusCode();
            HttpEntity responseEntity = response.getEntity();
            String responseString = EntityUtils.toString(responseEntity, "UTF-8");

            System.out.println("[" + statusCode + "] " + responseString);

        } catch (ClientProtocolException e) {
            System.err.println("Unable to make connection");
            e.printStackTrace();
        } catch (IOException e) {
            System.err.println("Unable to read file");
            e.printStackTrace();
        } finally {
            try {
                if (fis != null) fis.close();
            } catch (IOException e) {}

堆栈跟踪中给出的 url 末尾有一个空格

HttpPost httppost = new HttpPost("https://box.one.th/app/api/upload"); 请修剪网址。空格对于 URI 是无效的字符。

引用这个在 url URL encoding the space character: + or %20? 中添加特殊字符
