slack api : 上传到 slack 频道的文件

Posted 2023-02-25

【中文标题】slack api : 上传到 slack 频道的文件

【英文标题】：slack api : files to upload to slack channel

【发布时间】：2020-09-11 05:15:47

【问题描述】：

我正在尝试将图像从我的自动化套件发布到松弛通道。 要点击的网址：https://slack.com/api/files.upload Body 是表单数据类型，它有，

文件-图片文件上传 initial_comment - 一些字符串 channels - 要发布的松弛通道。

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);

我从 http post 获得成功响应。但是图片没有发布在松弛频道中。任何帮助！

问题出在标题上。实际上，即使是错误的标头，这个 slack api 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);
