如何在 String 和 JsonNode 之间转换使用 toString() 方法和 JsonNode(String) 构造函数
How to convert between String and JsonNode use toString() method and JsonNode(String) constructor
我只是需要一些指导来写这篇文章,以便我理解这个概念:
基本上我需要在 String 和 JsonNode 之间进行转换,我看到了一个说明该怎么做的答案,但作为新手开发人员,我不确定这意味着什么。如果我能看到它的实施,那将会有所帮助。
下面是我的 json 回复节点:
public void hitEndpoint(String endpoint) {
DataStore dataStore = DataStoreFactory.getScenarioDataStore();
HttpResponse<JsonNode> httpResponse;
String url = "xxx/xxx";
try {
httpResponse = Unirest.post(url)
.asJson();
dataStore.put("httpResponse", httpResponse);
...
}
下面我正在尝试转换值,以便我可以从 json:
中检索一个值
public void RetrieveExampleNode(String endpoint){
DataStore dataStore = DataStoreFactory.getScenarioDataStore();
JsonNode httpResponse = (JsonNode) dataStore.get("httpResponse");
String getExampleNode = httpResponse.getBody().getObject().getJSONArray("test").getJSONObject(0).get("example").toString();
//issue above is that it doesn't recognise getBody. When I remove getBody() and run the code, it still gives me a class cast exception error in the line where states JsonNode httpResponse = ...
}
JSON 正在尝试解析并由上面代码中的 httpResponse 当前检索:
{"test": [{"example": "2019-09-18T04:32:12Z"}, {"type": "application/json","other": {"name": Test Tester}}]}
我正在使用 uniRest 1.4.9
下面的例子是将 JSON 字符串转换为 JSON 对象
import org.json.JSONArray;
import org.json.JSONObject;
String jsonString = "{\"test\": [{\"example\": \"2019-09-18T04:32:12Z\"}, {\"type\": \"application/json\",\"other\": {\"name\": Test Tester}}]}";
JSONObject jsonObject = new JSONObject(jsonString);
已编辑答案
//For Get using Unirest
HttpResponse<JsonNode> httpResponse = Unirest.get("https://jsonplaceholder.typicode.com/posts/1").asJson();
String responseString = httpResponse.getBody().toString();
JSONObject object = new JSONObject(responseString); //Converting to JSONObject since it supports more functionalities
System.out.println(object.keySet());
//For Post using Unirest
httpResponse = Unirest.post("https://jsonplaceholder.typicode.com/posts").body("This is sample Body").asJson();
object = new JSONObject(responseString);
System.out.println(object.keySet());
