如何使用JavaREST模板添加原始数据(如以下示例)作为正文请求

{
  "body": {
    "content": "This is sent via postman to MS-team general channel"
  }
}

我在使用JavaREST模板发送请求体中的原始数据时遇到了困难,所以我在这里添加此代码以供将来参考(我是java编码的新手)

以下代码适用于我向MS团队频道发送消息

    public JSONObject sendMessage(String team_ID, String channel_ID){
        JSONObject res =null;        
        RestTemplate restTemplate = new RestTemplate();
        String url="https://graph.microsoft.com/beta/teams/"+team_ID+"/channels/"+channel_ID+"/messages";
        HttpHeaders headers = new HttpHeaders();
        headers.setContentType(MediaType.APPLICATION_JSON);                
        String token = "xxxxxxxxxx";
        headers.set("Authorization","Bearer "+token);
        


         // This  didn't worked 
        /*MultiValueMap<String, Object> map = new LinkedMultiValueMap<String, Object>();
        map.add("content", "Welcome to General channel message sent via intellij IDE");

        MultiValueMap<String, String> map1= new LinkedMultiValueMap<String, String>();
        map1.add("content", "Welcome to General channel message sent via intellij IDE");
        //map.add("body", "Welcome to General channel message sent via intellij IDE");*/
        
         // This one also didn't worked 
        //JSONObject jsonObject = new JSONObject();
        //jsonObject.put("body", "{ \"body\": {\"content\":\"Welcome to General channel message sent via intellij IDE  using java coding & http rest-Template\"}}");

        // This one also didn't worked 
        //JSONObject jsonObject = new JSONObject();
        //jsonObject.put("body", "{\"content\":\"Welcome to General channel message sent via intellij IDE  using java coding & http rest-Template\"}");
        
        // This one worked
        String requestJson = "{ \"body\": {\"content\":\"Welcome to General channel message sent via intellij IDE using java coding & http rest-Template\"}}";
        
                 
        // HttpEntity<String> request = new HttpEntity<String>(jsonObject.toString(),headers);
        HttpEntity<String> request = new HttpEntity<String>(requestJson,headers);
        ResponseEntity<String> response=null;
        try {
            response = restTemplate.postForEntity(url, request, String.class);
            res= new JSONObject(response.getBody());
            System.out.println(res);
        }catch(Exception e){
            e.printStackTrace();
        }
        return  res;
    }
publicJSONObject发送消息(字符串团队ID、字符串通道ID){
JSONObject res=null;
RestTemplate RestTemplate=新RestTemplate();
字符串url=”https://graph.microsoft.com/beta/teams/“+team_ID+”/channels/“+channel_ID+”/messages”;
HttpHeaders=新的HttpHeaders();
headers.setContentType(MediaType.APPLICATION_JSON);
字符串标记=“XXXXXXXXX”;
headers.set(“授权”、“承载人”+令牌);
//这不管用
/*MultiValueMap=新链接的MultiValueMap();
添加(“内容”,“欢迎通过intellij IDE发送到通用频道消息”);
MultiValueMap map1=新链接的MultiValueMap();
添加(“内容”,“欢迎通过intellij IDE发送到通用频道消息”);
//添加(“正文”,“欢迎通过intellij IDE发送通用频道消息”)*/
//这个也没用
//JSONObject JSONObject=新的JSONObject();
//put(“body”、“{\“body\”:{\“content\”:\“欢迎使用java编码和http rest模板通过intellij IDE发送通用通道消息”}”);
//这个也没用
//JSONObject JSONObject=新的JSONObject();
//put(“body”,“content\:\”欢迎使用java编码和http rest模板通过intellij IDE发送的常规频道消息\“}”);
//这个成功了
String requestJson=“{\'body\':{\'content\':\”欢迎使用java编码和http rest模板通过intellij IDE发送的常规频道消息\“}”;
//HttpEntity请求=新的HttpEntity(jsonObject.toString(),标头);
HttpEntity请求=新的HttpEntity(requestJson,headers);
ResponseEntity response=null;
试一试{
response=restTemplate.postForEntity(url、请求、字符串、类);
res=新的JSONObject(response.getBody());
系统输出打印项次(res);
}捕获(例外e){
e、 printStackTrace();
}
返回res;
}

您试过什么吗?如果是的话,你为什么不展示?若否,原因为何?
