发送数据 json 通过使用模板的邮政呼叫 rest 的 spring

我经常出错言说这是错误的 json, 并继续弄错 400. 我认为我没有正确格式化数据的实现。
目的：尝试使用模板进行拨打电话 rest, 传输数据 JSON 作为一个身体。 似乎在转换数据时 map 在 json 它们被错误地转化为 json.


public void GetJsonData/String name, String city/ {

 Map<string, string=""> map = new HashMap<string, string="">//;

 map.put/"api_key", apikey/;







map.put/"venue_queries", "[{'name':'"+name+"', 'location': {'locality': '"+city+"'}}]"/;



 try {

 String resp = GlobalHelper.calltestService/RestServicesUrl, map/;

 System.out.println/resp/;

 } catch /Exception e/ {

 // TODO Auto-generated catch block

 e.printStackTrace//;

 }

 }





public String calltestService/String url, Map<string, string=""> data/ throws Exception {

 RestTemplate rest = new RestTemplate//;

 HttpHeaders headers = new HttpHeaders//;

 headers.setContentType/MediaType.APPLICATION_JSON/;

 headers.setAccept/Arrays.asList/MediaType.APPLICATION_JSON//;

 ResponseEntity<string> response = new ResponseEntity<string>/headers, HttpStatus.OK/;

 rest.getMessageConverters//.add/new MappingJackson2HttpMessageConverter///;

 Gson gson = new Gson//;

 System.out.println/gson.toJson/data//;

 try {

 response = rest.postForEntity/url, gson.toJson/data/, String.class/;

 System.out.println/response.getBody///; 

 System.out.println/response.getHeaders///;

 return response.getBody//;

 } catch /Exception e/ {

 e.printStackTrace//;

 System.out.println/"error in post entity"/;

 return "error";

 }

 }

    对，你的结果 JSON 无效的


    {
    
 "venue_queries": "[{\u0027name\u0027:\u0027yo\u0027, \u0027location\u0027: {\u0027locality\u0027: \u0027Solares\u0027}}]",
    
 "api_key": "asfasdfasfdasdfasdfa"
    
}


    你 JSON 无效，因为 GSON 屏幕符号 HTML 默认值并将单引号放置为等效符号代码 unicode U+0027

    如果你禁用
    http://google-gson.googlecode. ... %2529

    GsonBuilder builder = new GsonBuilder//;
    
builder.disableHtmlEscaping//;
    
Gson gson = builder.create//;


    你会得到


    {
    
 "venue_queries": "[{'name':'yo', 'location': {'locality': 'Solares'}}]",
    
 "api_key": "asfasdfasfdasdfasdfa"
    
}


    无论如何，你的 JSON 还是错了。

    你必须纠正你的
    venue_queries

    地图上的主要内容
    using double quotes


    "



    map.put/"venue_queries", "[{\"name\":\""+name+"\", \"location\": {\"locality\": \""+city+"\"}}]"/;


    然后是你的结果 JSON 将有效


    {
    
 "venue_queries": "[{\"name\":\"yo\", \"location\": {\"locality\": \"Solares\"}}]",
    
 "api_key": "asfasdfasfdasdfasdfa"
    
}


    分段 Tes


    import java.util.HashMap;
    
import java.util.Map;
    
import java.util.Map.Entry;
    

    
import com.google.gson.Gson;
    

    
public class GsonMap {
    

    
 public static void main/String[] args/ {
    
 Map<string, string=""> map = new HashMap<string, string="">//;
    
 String apikey = "asfasdfasfdasdfasdfa";
    
 map.put/"api_key", apikey/;
    
 String name = "yo";
    
 String city = "Solares";
    
 map.put/"venue_queries", "[{\"name\":\""+name+"\", \"location\": {\"locality\": \""+city+"\"}}]"/;
    
 Gson gson = new Gson//;
    
 String json = gson.toJson/map/;
    
 System.out.println/"Resulting JSON:" + json/;
    
 map = gson.fromJson/json, map.getClass///;
    
 System.out.println/"Resulting map values:"/;
    
 for /Entry<string, string=""> entry : map.entrySet/// {
    
 System.out.println/"Key:" + entry.getKey// + ", value:" + entry.getValue///;
    
 }
    
 }
    
}
