I am trying to implement sample spring boot project and trying to retrieve result using POSTMAN application. But when using POSTMAN , I am not able to see that response for a GET request. But I can see by using browser properly. POSTMAN returning "Expected ':' instead of 't'" as result. But I can see result properly by using browser.
And my controller code is like the following,
#GetMapping("/check")
public List<Users> check() {
return (List<Users>) userObj.findAll();
}
Can anyone help me to find out why I am not able to see result using POSTMAN application please?
You are saying to postman (for that matter any client) that your api is producing json and instead you are returning just a string.
Check your header you will have a field called
Content-Type → application/json;charset=UTF-8
All you need to do is ensure you are sending valid json or remove that header entry so clients do not try to read it as json.
Or just to check you are getting right data by changing format from json to text in postman
You server application needs to understand the incoming request type. can you define the Content-Type=application/json and give a try.

I am trying to get an access token via RestTemplate.postForEntity().
myRestTemplate.postForEntity(authBaseUrl, request, Object.class);
I have a specific class for it, but let's use now a simple Object as type. It contains an access_token field.
It works, because I can get response, but the length if the access tokens (which is a string)
is 1196 character long. And I can get the same length in Postman too.
But if I use the intelliJ built-in REST client, the length is 1199.
Only the token from the intelliJ rest client works (So the longer).
Because I always get a new access token, it is impossible to get the same token twice.
How can I debug it?
What could be the problem?
Is the code that generates the response available to you? if so in your response add a header content-length so you can see what the server sent and what you received. Also, debug the server side and see what is being generated. In addition take another 3d party Http client and test it with this client see if you see a difference. The Http clients that you can try are Apache Http client, OK Http client, or my favorite - a very simplistic client written by me as part of my own Open Source MgntUtils library. Here is the Javadoc for my http client Here is a link to a similar question where you can get the references for any of above mentioned Http clients: How to check the status of POST endpoint/url in java
I am trying to implement sample spring boot project and to ensure my endpoints are working properly, i'm using POSTMAN. When using POSTMAN , I am not able to see the response(i.e in Pretty) for a POST request. But the Status is 200 OK and I am able to see the result using GET request.
No Pretty response for POST request
GET Response ensuring that the previous POST request works fine
And my controller code is the following
#PostMapping("/message")
public Message createMessage(#RequestBody Message message)
{
return service.createMessage(message);
}
Can anyone help me to find out why I am not able to see the result while using POST method please?
Like Rafael says it is good to return a Response with the object entity. I haven't been working with Spring myself but with JavaEE and in JavaEE it is perfectly possible to return the object directly without using a Response. I use Responses anyways though, because it is much nicer to work with, and you can create your own custom responses and status codes.
Maybe check if your createUser service actually returns a message.
I don't know much about Spring, but usually what works for me is using a ResponseEntity as the object returned by the function. Also, maybe you should use #RestController as the annotation to your class controller
#PostMapping("/message")
public ResponseEntity<Message> createMessage(#RequestBody Message message)
{
Message msg = service.createMessage(message);
return ResponseEntity.ok(msg);
}
I setup a GET scripted rest API. However, when I try to send a GET request with a body, ServiceNow (before it hits my code) complains that GET is not allowed to have a body.
Is there a way to disable this restriction? For now as a temporary workaround, I converted the request into a POST. However, this request does not change any state, so I believe it should be a GET. The request only searches for existing items.
GET is used without body, any configuration of a GET is in the URL and header. A query URL looks like this:
https://instance.service-now.com/api/now/table/problem?sysparm_query=active=true^ORDERBYnumber^ORDERBYDESCcategory&sysparm_limit=1
See the documentation here:
https://developer.servicenow.com/app.do#!/rest_api_doc?v=madrid&id=r_TableAPI-GET
Generally it's OK to use a POST to get data, graphQL does this for example, but i think SNOW is configured for GETs only.
I fetching data from an api end point.
When I use postman to send the request, I get an array of of objects (non empty).
However when I simply request it via the browser I get an array of empty objects...
Why is this happening?
You need to pass authorization token and Content-Type headers while making a request through the browser.
Browser only able to make a get request, it doesn't set header value(s) directly for you. You need to add extension of chrome like ModHeader, which will help you to set request and response header.
Moreover, I don't think you need to worry about it, as I assume you will need application internal call instead.
IN magento, as I am using REST api to get the product details with url like http://myserver.com/magento/api/rest/products? But this url returns only in XML format. But I need it in the JSON format.
Can anyone suggest me how to get it in JSON format without using REST client??
you need to set request header explicitly to application/json then the response is served in json.
