如何使用 java restTeplate 將原始數據添加到正文請求

Question

如何使用 java rest-template 添加如下示例的原始數據作為正文請求

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

Answer 1

我在使用 java 其余模板在請求正文中發送原始數據時遇到困難，所以我在此處添加此代碼以供將來參考（我是 java 編碼的新手）。

下面的代碼對我有用，可以向 MS-Team 頻道發送消息

    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;
    }
