slackapi:上传到slackchannel的文件

Question

我正试图将自动化套件中的图像发布到slack通道
要点击的URL：https://slack.com/api/files.upload
正文是表单数据类型，它有，

• 文件-图像文件上传
• initial_comment-某个字符串
• channels—要发布的空闲通道

我尝试在HttpPost 中使用MultipartEntity类

MultipartEntity multiPartEntity = new MultipartEntity();
FileBody fileBody = new FileBody(file);
//Prepare payload
multiPartEntity.addPart("file", fileBody);
multiPartEntity.addPart("file_type", new StringBody("JPG"));
multiPartEntity.addPart("initial_comment", new StringBody("cat shakes"));
multiPartEntity.addPart("channels", new StringBody("bot-e2e-report"));
//Set to request body
postRequest.setEntity(multiPartEntity);

我收到了来自http帖子的成功回复。但是这张图片没有发布在松弛的频道上。请帮忙！

问题出在标头上。实际上，即使对于错误的头，这个slackapi也会给出200响应。工作代码：

CloseableHttpClient httpclient = HttpClients.createDefault();
try {
//Set various attributes
MultipartEntityBuilder entitybuilder = MultipartEntityBuilder.create();
entitybuilder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
entitybuilder.addBinaryBody("file", file);
entitybuilder.addTextBody("initial_comment", "cat");
entitybuilder.addTextBody("channels","bot-e2e-report");
HttpEntity mutiPartHttpEntity = entitybuilder.build();
RequestBuilder reqbuilder = RequestBuilder.post("https://slack.com/api/files.upload");
reqbuilder.setEntity(mutiPartHttpEntity);
//set Header
reqbuilder.addHeader("Authorization", "Bearer xoxb-16316687382-1220823299362-fdkBklPrY7rc72bQk3WSOSjD");
HttpUriRequest multipartRequest = reqbuilder.build();
// call post
HttpResponse response = httpclient.execute(multipartRequest);
// Parse the response
HttpEntity entity = response.getEntity();
String json = EntityUtils.toString(entity, StandardCharsets.UTF_8);
System.out.println(json);
