使用Slack sdk for java将文件上传到slack

Question

我正在尝试使用slack sdk for java和file.upload method将文件上传到slack

我尝试过使用.file()和.fileData()，但在控制台中没有收到任何错误，事实上，在调用这两个方法中的任何一个之后，似乎都没有输出任何内容。使用content("something")方法时，我只得到"All ok“和松弛的消息。

下面是我的代码：

    File report = new File(System.getProperty("user.dir") + "\\report.zip");
    
    if(!report.exists()) {
        System.out.println("Report Zip Doesnt Exist");
        return false;
    }
    
    FilesUploadRequest request = FilesUploadRequest.builder()
            .channels(channels)
            .initialComment(comment)
            .filename(report.getName())
            //.file(report) doesnt work
            //.fileData(FileUtils.readFileToByteArray(report)) doesnt work
            .content("something") // works
            .title("Report")
            .filetype("zip")
            .build();

    try {
        FilesUploadResponse response = methods.filesUpload(request);
        if (response.isOk()) {
            System.out.println("All ok");
            return true;
        } else {
            System.out.println(response.getError());
            return false;
        }
    } catch (SlackApiException requestFailure) {
        System.out.println("Request failed");
        return false;
    } catch (IOException connectivityIssue) {
        System.out.println("Connectivity issue");
        return false;
    }

有一种方法

在slack ->中创建您的应用程序转到添加特性和功能->转到权限->转到范围-> Bot令牌作用域->使用生成的files.write ->令牌添加Oauth作用域

HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.MULTIPART_FORM_DATA);
headers.setBearerAuth(token); // pass generated token here
MultiValueMap<String, Object> bodyMap = new LinkedMultiValueMap<>();
bodyMap.add("file", bos.toByteArray(),fileName )); // convert file to ByteArrayOutputStream and pass with toByteArray() or pass with new File() 
bodyMap.add("initial_comment", message); // pass comments with file 
bodyMap.add("channels", "XXXXXX"); // pass channel codeID
HttpEntity<MultiValueMap<String, Object>> entity = new HttpEntity<>(bodyMap, headers);
ResponseEntity<Object> responseEntity = restTemplate.postForEntity("https://slack.com/api/files.upload", entity,
            Object.class);
System.out.println("sendEmailWithAttachment() response status: "+ responseEntity.getStatusCode().toString());
