【问题描述】：

我正在学习 Slack，目前我正在尝试获取用户的个人资料图片并将其发布在 Slack 通用频道中。

我尝试了users.profile.get api，我能够获得一些 JSON 响应，但不清楚将图像发布到频道。

收到的回复：

    }
}

我看过files.upload api 但不知道如何传递内容参数。

以下是用于向 Slack 发送消息的代码：

for (i = 0; i < arrayList.length; i++)
{
var rm = new sn_ws.RESTMessageV2();
rm.setHttpMethod('POST');
rm.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');
rm.setEndpoint('https://slack.com/api/chat.postMessage');
var bodyString = '';
bodyString += 'token=' + encodeURIComponent('TOKEN');
bodyString += '&channel=' + encodeURIComponent('CKZLVKNFM');
bodyString += '&text=' + encodeURIComponent('HBD ' + arrayList[i]);
rm.setRequestBody(bodyString);
var response1 = rm.execute();
var responsebody = response1.getBody();
var statuscode = response1.getStatusCode();
response1.getAllHeaders();}

运行以下代码后，从 SLACK 获取响应：

var rm = new sn_ws.RESTMessageV2();
     rm.setLogLevel('all');
    rm.setHttpMethod('POST');
    rm.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');
    rm.setEndpoint('https://slack.com/api/users.info');
    //encodeURIComponent
    var bodyString = '';
    bodyString += 'token=' + encodeURIComponent('xoxb-691106198192-692978264951-MxWbFRMgjb8xo6B9I3yHEu3i');
    bodyString += '&user=' + encodeURIComponent('UL4NBK3BK');
    //bodyString += 
    //bodyString += '&text=' + encodeURIComponent('HBD ' + arrayList[i] + ', ');
    rm.setRequestBody(bodyString);
    var response1 = rm.execute();
    var responsebody = response1.getBody();
    var statuscode = response1.getStatusCode();
    response1.getAllHeaders();
gs.info("Response: " +responsebody);
//var js = JSON.parse(responsebody);
//var jsf = JSON.stringify(responsebody);

var jss = JSON.stringify(JSON.parse(responsebody));
gs.info('Response Parsing: ' +jss);
gs.info('Response Parsing 11' +jss.user.profile.real_name);

粘贴收到的响应：

我现在收到了回复，但请检查我能够发送消息但无法发布图像的编码 URI。我可以手动设置网址，现在可以看到图片了。

var rm1 = new sn_ws.RESTMessageV2();
    //rm.setLogLevel('all');
    rm1.setHttpMethod('POST');
    rm1.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');
    rm1.setEndpoint('https://slack.com/api/chat.postMessage');
    //encodeURIComponent
    var bodyString1 = '';
    bodyString1 += 'token=' + encodeURIComponent('xoxb-691106198192-692978264951-MxWbFRMgjb8xo6B9I3yHEu3i');
    bodyString1 += '&channel=' + encodeURIComponent('CKZLVKNFM');
bodyString1 += '&image_url=' +encodeURIComponent(grimage.user.profile.image_512);
    bodyString1 += '&text=' + encodeURIComponent('Congrats hhhh' );
    rm1.setRequestBody(bodyString1);

    var response11 = rm1.execute();
    var responsebody1 = response11.getBody();
    var statuscode1 = response11.getStatusCode();
    response11.getAllHeaders();

【问题讨论】：

如果您使用的是 node.js，我建议您查看 Slack 的官方 Slack API 库。它使 Slack API 的开发变得更容易：github.com/slackapi/node-slack-sdk
kk。您可以选择任何以image_ 开头的网址。它们都是相同的图像，只是分辨率不同。所以image_512 是 512x512 像素。
我建议先将您从 API 获得的 JSON 转换为带有 JSON.parse 的对象。然后你可以更好地使用 URL。
您在 cmets 中发布的代码具有 JSON 格式的 URL，这将不起作用。您需要先将它们解析为 JS 对象。使用 JSON.parse()

【解决方案1】：

files.upload 要求您先将图像下载到本地服务器，然后再将其上传到 Slack。

这是一种非常强大的 API 方法，但在您的情况下可能没有必要，因为个人资料图片已经托管在 Slack 云上。

相反，我建议只在普通消息帖子的附件中包含图像 URL。由于这些 URL 是公开的，因此它们可以正常工作。

使用chat.postMessage 等发送的 JSON 格式的示例消息：

{
    "channel": "test",
    "attachments":
    [
        {
            "text": "Profile pic",
            "image_url": "https://secure.gravatar.com/avatar/d6ada88a40de8504c6b6068db88266ad.jpg?s=512&d=https%3A%2F%2Fa.slack-edge.com%2F27b6e%2Fimg%2Favatars%2Fsmiley_blobs%2Fava_0016-512.png"
        }

    ]
}

如果您想知道示例中 URL 中的额外反冲。该字符串是 JSON 编码的，需要先解码（我为 URL 做了解码）。

以下是有关如何向频道发送带有个人资料图片的用户的消息的概述：

使用他们的 Slack 用户 ID 获取您要向其发送消息的用户列表（如果您没有 Slack 用户 ID，请致电 users.list 并根据电子邮件地址进行匹配）。
为每个用户致电users.get.profile 以获取他们的图片网址
向每个用户发送消息。将图片 URL 添加为附件（参见我的示例）。

确保遵守 API 调用的速率限制，例如最大限度。每秒 1 条消息。

我可能还会在消息中添加对每个用户的提及，您可以通过在文本中添加 <@U1234567>（使用正确的用户 ID）来做到这一点。

嗨 Erik，议程是根据我们需要发送消息和照片的生日向 Slack 用户发送生日消息。目前我们有 Servicenow 到 Slack 的集成，现在我们正在从 ServiceNow 中提取 DOB，并使用 chat.postMessage api 在 Slack 中发布消息。现在的挑战是发送用户的图片。你能帮我解决这个问题吗？？？
