We Keep Coding

okhttp call paybylink bad request but it does work in postman

I am trying to connect to pay by link by json.
We first tried with json and it worked like a charm.
I used the code postman provided to create this,
But we keep getting 400 bad request,
If we change the credentials we get unauthorized, se wo know it's not that
But if we go look in the request log of pay by link we see that the request send from java does not appear here at all, it does not show error, but nothing.
Does anybody know how we can fix it?
Thanks in advance!
Sincerely,
Laurens

Okhttp3 Base URL for calling

I am using an OkHttp Client for my Webservice call, its working successfully with JAVA Main function and returning response.
Now, I want to call this client from Postman; but I dont know what URL Shall i call? Like in jersey we create a base URL from #PATH annotation in Spring we use #service. What shall be done in okhttp to create a base url to call? Please help.
public String soapCaller() throws IOException, JSONException {
Response response = null;

OkHttpClient client = new OkHttpClient();

When sending okhttp request: HTTP ERROR 405 and invalid_client

I'm making a request to a website. However, I keep getting a returned JSON of {"error":"invalid_client"}. Additionally, when I navigate to the URL I'm making the request to through a web browser it shows HTTP ERROR 405.
From what I read on those errors that might mean that my request isn't structured correctly.
According to the API's documentation, this is an example of the request type I'm trying to do:
OkHttpClient client = new OkHttpClient();
MediaType mediaType = MediaType.parse("application/x-www-form-urlencoded");
RequestBody body = RequestBody.create(mediaType, "client_secret={your_client_secret}&client_id={your_client_id}&code={your_authorization_code}&grant_type=authorization_code&redirect_uri={your_redirect_uri}");
Request request = new Request.Builder()
.url("https://api.website.com/v2/oauth2/token")
.post(body)
.addHeader("content-type", "application/x-www-form-urlencoded")
.addHeader("cache-control", "no-cache")
.build();
Response response = client.newCall(request).execute();
From what I can tell mine should be doing the same thing, just a little differently.
Here is a Pastebin of my doInBackground method (I'm using AsynchTask). Here is the more applicable part:
OkHttpClient client = new OkHttpClient();
// A section here gets strings from a JSON file storing values such as client_id
RequestBody bodyBuilder = new FormBody.Builder()
.add("client_secret", CLIENT_SECRET)
.add("client_id", CLIENT_ID)
.add("code", AUTHORIZATION_CODE)
.add("grant_type", GRANT_TYPE)
.add("redirect_uri", REDIRECT_URI)
.build();
System.out.println("Built body: " + bodyBuilder.toString());
String mediaTypeString = "application/x-www-form-urlencoded";
MediaType mediaType = MediaType.parse(mediaTypeString);
RequestBody body = RequestBody.create(mediaType, requestbodyToString(bodyBuilder)); // See Edit 1
Request request = new Request.Builder()
.url(TARGET_URL)
.post(body)
.addHeader("content-type", mediaTypeString)
.addHeader("cache-control", "no-cache")
.build();
try {
System.out.println("Starting request.");
Response response = client.newCall(request).execute();
String targetUrl = request.url().toString() + bodyToString(request);
System.out.println("request: " + targetUrl);
String responseBodyString = response.body().string();
System.out.println("response: " + responseBodyString);
return responseBodyString;
} catch (IOException ex) {
System.out.println(ex);
}
Like I said, I keep getting a returned JSON of {"error":"invalid_client"}, and when I navigate to the URL I'm making the request to through a web browser it shows HTTP ERROR 405.
I'd love to provide as much additional information as you need. Thanks!
Edit 1: The second parameter of this used to be "bodyBuilder.toString()", but I changed it because I realized it wasn't actually sending the body. The result is still the same - {"error":"invalid_client"}. The method now used comes from here.

I figured out what it was - I hadn't actually been writing the authentication_code to the file, only adding it to another JSONObject. Oops. :)

Spring Boot multipart content type HTTP Request using RestTemplate

I am trying to emulate this request using RestTemplate in Spring Boot
curl -X POST
'https://my.craftar.net/api/v0/image/?api_key=123456789abcdefghijk123456789abcdefghijk'
-F "item=/api/v0/item/4fe672886ec142f6ab6d72d54acf046f/"
-F "file=#back_cover.png"
Here's my code:
MultiValueMap<String, Object> params= new LinkedMultiValueMap<>();
params.add("item", "/api/v0/item/4fe672886ec142f6ab6d72d54acf046f/");
final String filename=file.getOriginalFilename();
Resource contentsAsResource = new ByteArrayResource(file.getBytes()){
#Override
public String getFilename(){
return filename;
}
};
HttpHeaders imageHeaders = new HttpHeaders();
imageHeaders.setContentType(MediaType.IMAGE_PNG);
HttpEntity<Resource> imageEntity = new HttpEntity<Resource>(contentsAsResource, imageHeaders);
params.add("file", imageEntity);
HttpHeaders headers = new HttpHeaders();
headers.setAccept(Collections.singletonList(MediaType.ALL));
headers.setContentType(MediaType.MULTIPART_FORM_DATA);
HttpEntity<MultiValueMap<String,Object>> requestEntity =new HttpEntity<>(params,headers);
try {
ResponseEntity<String> responseEntity = restTemplate.exchange(url,HttpMethod.POST, requestEntity, String.class);
return responseEntity.getBody();
} catch (final HttpClientErrorException httpClientErrorException) {
return httpClientErrorException.getResponseBodyAsString();
} catch (Exception exception) {
return exception.getMessage();
}
The above request throws a HttpClientErrorException and this what the response body looks like
{"error": {"message": "Expected multipart/form-data; boundary=<..> content but got multipart/form-data;boundary=x6G0xWVxdZX4n8pYNU8ihGAnCg4Twj3DgMARYDs.", "code": "WRONG_CONTENT_TYPE"}}
I have also tried using FileSystemResource, but it throws the same exception. The problem probably lies in formatting the data in multipart content-type.
If it can help, this is the code template generated by Postman on a successful request using Okhttp.
OkHttpClient client = new OkHttpClient();
MediaType mediaType = MediaType.parse("multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW");
RequestBody body = RequestBody.create(mediaType,
"------WebKitFormBoundary7MA4YWxkTrZu0gW\r\n
Content-Disposition: form-data; name=\"item\"\r\n\r\n/api/v0/item/3d8dcdd1daa54bcfafd8d1c6a58249b5/\r\n------WebKitFormBoundary7MA4YWxkTrZu0gW\r\n
Content-Disposition: form-data; name=\"file\"; filename=\"times_logo.png\"\r\nContent-Type: image/png\r\n\r\n\r\n------WebKitFormBoundary7MA4YWxkTrZu0gW--");
Request request = new Request.Builder()
.url("https://my.craftar.net/api/v0/image/?api_key=c6d4750c7368806fab27294fba8d0f93d48e1e11")
.post(body)
.addHeader("content-type", "multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW")
.addHeader("cache-control", "no-cache")
.addHeader("Postman-Token", "cf09a989-338e-4d68-8968-b30a43384e5f")
.build();
Response response = client.newCall(request).execute();

just add the Resource to params instead of creating a HttpEntity
params.add("file", contentsAsResource);

How to generate access token on OS version 19 for payment gateway

This code is working in os version 5.1 and above.
Access token is not generated in 5.0 os version and below.
// getting exception ssl layer connection closed by peer
OkHttpClient client = new OkHttpClient.Builder()
