将附件上传至 azure devops [REST API]

Question

我很难在我的 azure devops repo 中通过 api 添加附件。

public static void putAttachments(Integer id) {
        try {
            URL url = new URL(
                    "https://dev.azure.com/marcoparra0034/AgileFr/_apis/wit/attachments?api-version=5.1&fileName=imageAs.png");
            HttpURLConnection con = ResApiMain.apiConnectionAttachments(PAT, url);
            File file = new File("C:\\Users\\marco.parra\\Pictures\\Screenshots\\new.png");
            String base64Image = encodeFileToBase64Binary(file);

//                  String jsonInputString = "[{\"op\":\"add\",\"path\":\"/fields/System.Title\",\"value\":\"" + "tpain"
//                          + "\"}]";
            base64Image = "[" + base64Image + "]";
            System.out.println("Base xs" + base64Image);

            try (OutputStream os = con.getOutputStream()) {
                byte[] input = Base64.decodeBase64(base64Image.getBytes("utf-8"));
                System.out.println(new String(input));
                os.write(input, 0, input.length);
            } catch (Exception ex) {
                System.out.println(ex.getMessage());
            }

            try (BufferedReader br = new BufferedReader(new InputStreamReader(con.getInputStream(), "utf-8"))) {
                StringBuilder response = new StringBuilder();
                String responseLine = null;
                while ((responseLine = br.readLine()) != null) {
                    response.append(responseLine.trim());
                }
                System.out.println(response.toString());
            } catch (Exception ex) {
                System.out.println(ex.getMessage());
            }
            con.disconnect();
        } catch (Exception ex) {

        }

这是连接方法

public static HttpURLConnection apiConnectionAttachments(String PAT, URL url) {
        HttpURLConnection con = null;
        try {
            String AuthStr = ":" + PAT;
            Base64 base64 = new Base64();

            String encodedPAT = new String(base64.encode(AuthStr.getBytes()));
            con = (HttpURLConnection) url.openConnection();
            con.setRequestProperty("Authorization", "Basic " + encodedPAT);
            con.setDoOutput(true);
            System.out.println("URL - " + url.toString());
            System.out.println("PAT - " + encodedPAT);

            // Image Requierements
//          con.setRequestProperty("Content-Type", "image/jpeg");
            con.setDoInput(true);
            con.setUseCaches(false);
            con.setRequestProperty("X-HTTP-Method-Override", "PATCH");
            con.setRequestMethod("POST");

            con.setRequestProperty("Content-Type", "application/octet-stream");
//      con.setRequestProperty("Accept", "application/json");

        } catch (Exception e) {
            System.out.println(e.getMessage());
        }
        return con;
    }

当我运行这个程序时，它显示了下一个错误代码。

Server returned HTTP response code: 405 for URL: https://dev.azure.com/marcoparra0034/AgileFr/_apis/wit/attachments?api-version=5.1&fileName=imageAs.png

更新 我看到了如何用python和c#工作，但我不能按照这个逻辑来创建一个附件

期望示例

{
  "id": "a5cedde4-2dd5-4fcf-befe-fd0977dd3433",
  "url": "https://dev.azure.com/fabrikam/_apis/wit/attachments/a5cedde4-2dd5-4fcf-befe-fd0977dd3433?fileName=imageAsFileAttachment.png"
}

任何帮助将被感激...。

我解决了这个问题，在con.setRequestProperty("X-HTTP-Method-Override", "PATCH")这一行做了注释。
