如何从Postman到Java获取Body原始JSON数据

Question

I have the variable customer-id and a value in the raw data in JSON format. I want to get the value from postman to java. How can I implement it?

Answer 1

It is not a good idea to use Postman in Java.

But you can do the same thing using Java.

First, you should call the same endpoint that Postman calls. You can use Unirest to access this endpoint.

Unirest.post("http://api.callme.com/json")
    .asJson()

It is good to observe the METHOD that is called on Postman and use the same on Unirest. In the code above, I'm using the method POST.

Then, you will get a JSON object.

HttpURLconnection

 String url = "http//url"; //define the url here
    URL obj; //making the object 
    obj = new URL(url);         
    HttpURLConnection con = (HttpURLConnection) obj.openConnection();
    con.setRequestMethod("GET");

//add authorisation if you have any

con.setRequestProperty("Content-Type", "application/json");
con.setRequestProperty("Accept-Language", "UTF-8");
int responseCode = con.getResponseCode();
System.out.println("\nSending 'GET' request to URL : " + url);
System.out.println("Response Code : " + responseCode);
JSONObject jsonObject = new JSONObject(response.toString());
String nid = jsonObject.get("customer-id").toString();

Answer 3

You should have to set content type to application/json . And in your java web application side, you can fetch that json from request. If you are using servlet then you have to use request.getParameter("customer-id");
