以json身份发送请求体，通过HTTPEntity获取请求 [英] Sending Request body as json to GET request through httpentity

问题描述

以Json身份发送外部API的GET请求的请求正文示例。

下面是示例json，需要在请求正文中添加才能通过GET请求发送 至外部接口： ‘

        {"nameidentify":["Name-1","Name-2","Name-3"]}
                
         '''
        
         'Assume i am getting values from one API like.. "Name-1","Name-2","Name-3" those values i need to 
      pass to other API through GET request.For example below i am hardcoding the values for reference...'
        
         
        '''
        String[] namesArray={"Name-1","Name-2","Name-3"}
            JSONObject jsobObject=new JSONObject();
            jsonObject.put("nameidentify",namesArray);
            
            HttpHeaders headers=new HttpHeaders();
            headers.add("Accept",MediaType.APPLICATION_JSON);
            headers.add("Content-Type",MediaType.APPLICATION_JSON);
            
            HttpEntity<String> otherentity=new HttpEntity<>(jsobObject.toString(),headers);
            
            


List<Map>getnameResponse=restTemplate.
exchange(externalAPIurl,HttpMethod.GET
,otherentity,ArrayList.class)
.getBody();
             
          

当我调用外部API时，收到上述代码的400个错误请求。可能是他们没有收到的身体。有谁能对此提供一些想法。提前谢谢…… ‘

推荐答案

请编写代码可能有帮助。这对我很管用，从&q；Res&q；取回你的POJO。

import org.springframework.web.client.RestTemplate;
import com.google.gson.JsonObject;
import org.springframework.http.HttpHeaders;
import org.springframework.http.HttpEntity;
import org.springframework.http.HttpMethod;
import org.springframework.http.MediaType;


RestTemplate restTemplate = new RestTemplate();
            
String url = "<external api url>";
            
JsonObject jsobObject=new JsonObject();
jsobObject.addProperty("someJsonProperty", "someJsonPropertyValue");
HttpHeaders headers=new HttpHeaders();
headers.add("Accept", MediaType.APPLICATION_JSON.toString());
headers.add("Content-Type",MediaType.APPLICATION_JSON.toString());
            
HttpEntity<String> httpEntity = new HttpEntity<>(jsobObject.toString(), headers);
            
String res = restTemplate.exchange(url, HttpMethod.GET, httpEntity, String.class).getBody();
