Good Day,
I have created a java class in Adapter IBM Mobilefirst Platform that will get response from the Jax-ws service.
// read direct to soap service - 4/4/2017
protected JSONObject createJsonObjectFrmSOAPRequest(Map mapsData) throws IOException, SOAPException {
JSONObject jsonObj = new JSONObject();
String responseSoap="";
// Create SOAP Connection
SOAPConnectionFactory soapConnectionFactory = SOAPConnectionFactory.newInstance();
SOAPConnection soapConnection = soapConnectionFactory.createConnection();
try {
// Send SOAP Message to SOAP Server
String url = "http://XXXXX:001/test-pvr-ws/empl_get";
SOAPMessage soapResponse = soapConnection.call(createSOAPRequest(mapsData), url);
// Process the SOAP Response
responseSoap = printSOAPResponse(soapResponse);
// how to convert to jsonobject, the output is in xml string
// XMLToJSONTransformer.transform(responseSoap); - don't know how to use XMLToJSONTransformer
//JSONObject.parse(responseSoap); // convert String to JSONObject
logger.info("jsonObject : " + jsonObj);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return jsonObj;
}
protected String printSOAPResponse(SOAPMessage soapResponse) throws Exception {
String finalstringEnv = "";
try {
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();
Source sourceContent = soapResponse.getSOAPPart().getContent();
System.out.print("\nResponse SOAP Message = ");
//create a StringWriter for the output
StringWriter outWriter = new StringWriter();
// StreamResult result = new StreamResult(System.out); // this is for print line output
StreamResult result = new StreamResult(outWriter);
transformer.transform(sourceContent, result);
// how to convert Transformer.transform() to String java
StringBuffer sb = outWriter.getBuffer();
finalstringEnv = sb.toString();
} catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
}
return finalstringEnv;
}
2 . This code will get the Response in XML string, but I don't know how to use library com.ibm.json.*. Which I wanted to convert the String Response to JSONObject.
2.1. Result Response in XML Soap Envelope (example successful Result i got).
<?xml version="1.0" encoding="UTF-8"?><soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Body>
<a:getTheResponse xmlns:a="http://XXXXX:001/test-pvr-ws/empl_get/">
<getTheRecord>
<statusCode>0</statusCode>
<getTheRecord>
<userid>1212</userid>
</a:getTheResponse>
</soapenv:Body>
</soapenv:Envelope>
2.2. responseSoap String variable i need to convert String XML Soap response To JSONObject
// Process the SOAP Response
responseSoap = printSOAPResponse(soapResponse);
//.............. code to convert String XML Soap response To JSONObject
I answer my Question:
Recently I just trying , I need to use this method XMLToJSONTransformer (com.ibm.json.xml.XMLToJSONTransformer) to convert the XML string to JSONObject.
String jsonObjectStr ="";
// convert String to JSONObject
jsonObjectStr = xmlToJsonTransformer.transform(responseSoap);
jsonObj = JSONObject.parse(jsonObjectStr);
I'm trying to invoke following code.
// object
LoginVM loginVM = new LoginVM();
loginVM.setUserName("admin");
loginVM.setUserPassword("s#1234");
loginVM.setClientIpAddress("::1");
loginVM.setIsPinActive(false);
loginVM.setLoginWithPIN(false);
//connection
URL url = new URL("http://192.168.202.118/UMService/UserLogin/Login");
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setDoOutput(true);
conn.setRequestMethod("POST");
conn.setRequestProperty("Accept", "application/json");
conn.setRequestProperty( "Content-Type", "application/json");
conn.setDoOutput(true); //this is to enable writing
conn.setDoInput(true); //this is to enable reading
ObjectMapper mapper = new ObjectMapper();
String jsonInString = mapper.writeValueAsString(loginVM);
System.out.println(jsonInString);
ObjectOutputStream out = new ObjectOutputStream(conn.getOutputStream());
out.writeObject(jsonInString);
out.flush();
The service is successfully . But LoginVM 's values got null.Could you please point what is the error I have made?
Should work with something like:
JSONParser parser = new JSONParser();
JSONObject jsonObj = (JSONObject) parser.parse(jSonResponse);
You need to check the object in which you are assigning the response.
Also, check among JsonObject or array accordingly.
I am getting a JSON object POST request from android volley.I am trying to read the json using the following code.
#POST
#Path("/driver/insertTripLog")
#Consumes(MediaType.APPLICATION_JSON)
#Produces(MediaType.TEXT_PLAIN)
public String insertTripLog(InputStream incomingData) throws Exception
{
StringBuilder sb = new StringBuilder();
try {
BufferedReader in = new BufferedReader(new InputStreamReader(incomingData));
String line = null;
while ((line = in.readLine()) != null) {
sb.append(line);
}
} catch (Exception e) {
System.out.println("Error Parsing: - ");
}
String data=sb.toString();
System.out.println("Data Received: " +data );
return data;
}
The output i am getting json object but the special characters are encoded with %XX format.
Sample Output:
json=%5B%7B%22name%22%3A%22value%22%7D%5D
how to read properly post json data sent from volley.
Use the URLDecoder class to handle the percent encoded content which you are seeing:
String data = sb.toString();
data = java.net.URLDecoder.decode(data, "UTF-8");
Output:
json=[{"name":"value"}]
I am struggling to make an HTTP POST request with JSON object as data.
As you can see below, first I created an HTTP Post request. Then I commented out part of it and attempted to modify it in order to add JSON related code.
Any advice about how to make this code work would be much appreciated.
import java.io.*;
import java.net.*;
import org.json.simple.JSONObject;
public class HTTPPostRequestWithSocket {
public void sendRequest(){
try {
JSONObject obj = new JSONObject();
obj.put("instructorName", "Smith");
obj.put("courseName", "Biology 101");
obj.put("studentName1", "John Doe");
obj.put("studentNumber", new Integer(100));
obj.put("assignment1", "Test 1");
obj.put("gradeAssignment1", new Double("95.3"));
/*
//Note that this code was taken out in order to attempt to send
//the information in the form of JSON.
String params = URLEncoder.encode("param1", "UTF-8")
+ "=" + URLEncoder.encode("value1", "UTF-8");
params += "&" + URLEncoder.encode("param2", "UTF-8")
+ "=" + URLEncoder.encode("value2", "UTF-8");
*/
String hostname = "nameofthewebsite.com";
int port = 80;
InetAddress addr = InetAddress.getByName(hostname);
Socket socket = new Socket(addr, port);
String path = "/nameofapp";
// Send headers
BufferedWriter wr = new BufferedWriter(new
OutputStreamWriter(socket.getOutputStream(), "UTF8"));
wr.write("POST "+path+" HTTP/1.0rn");
wr.write("Content-Length: "+obj.length()+"rn");
wr.write("Content-Type: application/x-www-form-urlencodedrn");
wr.write("rn");
// Send parameters
wr.write(obj);
wr.flush();
// Get response
BufferedReader rd = new BufferedReader(new InputStreamReader(socket.getInputStream()));
String line;
while ((line = rd.readLine()) != null) {
System.out.println(line);
}
wr.close();
rd.close();
socket.close();//Should this be closed at this point?
}catch (Exception e) {e.printStackTrace();}
}
}
I am having problems indexing in elasticsearch. I have a function which creates an index and another one that creates a type mapping for a json I will be indexing. Both of these work fine but when I try calling the function to index something, it gives me a WebException saying that the remote server returned an error: (503) Server Unavailable. Any help will be greatly appreciated! Thanks!
This is my code:
public static void Main(string[] args)
{
string endpoint = "http://localhost:9200";
string index = "logs";
string type = "activity-log";
createIndex(endpoint, index);
createMapping(endpoint, index, type);
indexEvent(endpoint, index, type);
}
public static void createIndex(string endpoint, string index)
{
//Build request url
WebRequest request = WebRequest.Create(string.Format("{0}/{1}/", endpoint, index));
request.ContentType = "application/json"; //set content type of json
request.Method = "PUT"; //use POST method when creating an index
string json = "{\"settings\":{\"number_of_shards\":3,\"number_of_replicas\":2}}";
byte[] byteData = Encoding.GetEncoding("UTF-8").GetBytes(json);
string result = System.Convert.ToBase64String(byteData);
Stream dataStream = request.GetRequestStream();
dataStream.Write(byteData, 0, byteData.Length);
dataStream.Close();
//create a web response
WebResponse response = request.GetResponse();
StreamReader sr = new System.IO.StreamReader(response.GetResponseStream());
Console.WriteLine(sr.ReadToEnd().Trim());
Console.ReadKey();
response.Close();
}
public static void createMapping(string endpoint, string index, string type)
{
//Build request url
WebRequest request = WebRequest.Create(string.Format("{0}/{1}/{2}/_mapping", endpoint, index, type));
request.ContentType = "application/json"; //set content type of json
request.Method = "PUT"; //use POST method when creating an index
string json = "{\"activitylogevent\":{\"properties\":{\"id\":{\"type\":\"string\",\"index\":\"not_analyzed\"},\"parentId\":{\"type\":\"string\",\"index\":\"not_analyzed\"},\"event\":{\"type\":\"string\",\"index\":\"not_analyzed\"}}}}";
byte[] byteData = Encoding.GetEncoding("UTF-8").GetBytes(json);
string result = System.Convert.ToBase64String(byteData);
Stream dataStream = request.GetRequestStream();
dataStream.Write(byteData, 0, byteData.Length);
dataStream.Close();
//create a web response
WebResponse response = request.GetResponse();
StreamReader sr = new System.IO.StreamReader(response.GetResponseStream());
Console.WriteLine(sr.ReadToEnd().Trim());
Console.ReadKey();
response.Close();
}
public static void indexEvent(string endpoint, string index, string type)
{
//build the request URL
WebRequest request = WebRequest.Create(string.Format("{0}/{1}/{2}/", endpoint, index, type);
request.ContentType = "application/json"; //set content type of json
request.Method = "POST"; //use POST method when indexing a record without specifying id, and PUT when you specify an id
string jsonEvent = "{\"id\":\"123546789\",\"parentId\":\"abc123\",\"event\":\"CloseAccount\"}";
byte[] byteData = Encoding.GetEncoding("UTF-8").GetBytes(json);
string result = System.Convert.ToBase64String(byteData);
Stream dataStream = request.GetRequestStream();
dataStream.Write(byteData, 0, byteData.Length);
dataStream.Close();
//create a web response
WebResponse response = request.GetResponse();
Console.WriteLine("after get response");
Console.ReadLine();
StreamReader sr = new System.IO.StreamReader(response.GetResponseStream());
Console.WriteLine(sr.ReadToEnd().Trim());
Console.ReadKey();
response.Close();
}
I was doing something wrong in my createIndex function but here is my working function incase anyone finds it helpful:
public static void createIndex(string endpoint, string index)
{
//Build request url
WebRequest request = WebRequest.Create(string.Format("{0}/{1}/", endpoint, index));
request.ContentType = "application/json"; //set content type of json
request.Method = "PUT"; //use PUT method when creating an index
string json = "{\"settings\":{\"activity-log-events\":{\"number_of_shards\":3,\"number_of_replicas\":2}}}";
byte[] byteData = Encoding.GetEncoding("UTF-8").GetBytes(json);
string result = System.Convert.ToBase64String(byteData);
Stream dataStream = request.GetRequestStream();
dataStream.Write(byteData, 0, byteData.Length);
dataStream.Close();
//create a web response
WebResponse response = request.GetResponse();
StreamReader sr = new System.IO.StreamReader(response.GetResponseStream());
Console.WriteLine(sr.ReadToEnd().Trim());
Console.ReadKey();
response.Close();
}
You have at least one error in your indexEvent() function. You are setting the string jsonEvent but then using an undefined string json when setting up byteData:
string jsonEvent = "{\"id\":\"123546789\",\"parentId\":\"abc123\",\"event\":\"CloseAccount\"}";
byte[] byteData = Encoding.GetEncoding("UTF-8").GetBytes(json);
You'll note that you are doing this correctly in the other two functions, using the string json in both places. From createIndex:
string json = "{\"settings\":{\"number_of_shards\":3,\"number_of_replicas\":2}}";
byte[] byteData = Encoding.GetEncoding("UTF-8").GetBytes(json);
and from createMapping:
string json = "{\"activitylogevent\":{\"properties\":{\"id\":{\"type\":\"string\",\"index\":\"not_analyzed\"},\"parentId\":{\"type\":\"string\",\"index\":\"not_analyzed\"},\"event\":{\"type\":\"string\",\"index\":\"not_analyzed\"}}}}";
byte[] byteData = Encoding.GetEncoding("UTF-8").GetBytes(json);
There may be other things wrong in the code but that's definitely not going to work.
I made a some changes to my createIndex function and it worked. I posted the changes above.
