I am calling rest api(thingworx url) from java eclipse but throwing error in java.Below is my code

 

String b64 = Base64.getEncoder().encodeToString(bytes);

//Construct jsoninput body//

JSONObject params=new JSONObject();

params.put("path","/Motivation.pdf");

params.put("content", b64);

 

//Load pdf to Thingworx repository//

String url = "HiddenServerurlforsafetypurpose/Thingworx/Things/komal_FileRepo/Services/SaveBinary";

 

URL obj = new URL(url);

 

HttpURLConnection con = (HttpURLConnection) obj.openConnection();

 

//add request header

 

con.setRequestMethod("POST");

 

con.setRequestProperty("Accept", "application/json");

 

con.setRequestProperty("Content-Type", "application/json");

 

con.setRequestProperty("appKey", "removedforsafetypurpose");

 

con.setRequestProperty("Body", params.toJSONString());

 

// Send post request

 

con.setDoOutput(true);

 

DataOutputStream wr = new DataOutputStream(con.getOutputStream());

 

wr.flush();

 

wr.close();

 

int responseCode = con.getResponseCode();

 

System.out.println("\nSending 'POST' request to URL : " + url);

 

System.out.println("Response Code : " + responseCode);

 

BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream()));

 

String inputLine;

 

StringBuilder response = new StringBuilder();

 

while((inputLine = in.readLine()) != null) {

 

response.append(inputLine);

 

}

 

in.close();

 

//print result

 

System.out.println(response.toString());

 

Error in Thingworx :

Hi @KN_9954684 

 

I think there is some bug in the code. You are setting Body as POST Header Property.

 

Please refer to this one -

In the first example they are not setting body.

 

As per second example I set the body and changed the code but still I am getting error as "No path was specified"

 

Please check below code

 

String url = "Hiddenforsecuritypurpose/Things/komal_FileRepo/Services/SaveBinary";

 

String jsonInputString = "{"+"path"+":"+"/Motivation.pdf"+","+"content"+":"+b64+"}";

 

 

URL obj = new URL(url);

 

HttpURLConnection con = (HttpURLConnection) obj.openConnection();

 

//add request header

 

con.setRequestMethod("POST");

 

con.setRequestProperty("Accept", "application/json");

 

con.setRequestProperty("Content-Type", "application/json; charset=UTF-8");

 

con.setRequestProperty("appKey", "Hidden");

 

//con.setRequestProperty("Body", jsonInputString);

 

 

// Send post request

 

con.setDoOutput(true);

 

// DataOutputStream wr = new DataOutputStream(con.getOutputStream());

//

// wr.flush();

//

// wr.close();

//

// int responseCode = con.getResponseCode();

//

// System.out.println("\nSending 'POST' request to URL : " + url);

//

// System.out.println("Response Code : " + responseCode);

//

// BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream()));

//

// String inputLine;

//

// StringBuilder response = new StringBuilder();

//

// while((inputLine = in.readLine()) != null) {

//

// response.append(inputLine);

//

// }

//

// in.close();

//

// //print result

//

// System.out.println(response.toString());

try(OutputStream os = con.getOutputStream()) {

byte[] input = jsonInputString.getBytes("utf-8");

os.write(input, 0, input.length);

}

try(BufferedReader br = new BufferedReader(

new InputStreamReader(con.getInputStream(), "utf-8"))) {

StringBuilder response = new StringBuilder();

String responseLine = null;

while ((responseLine = br.readLine()) != null) {

response.append(responseLine.trim());

}

System.out.println(response.toString());

}
