如何在Java中获取没有转义序列的post请求的响应主体？

Question

I am trying to convert the HttpResponse's response body to a String using the following piece of code:

HttpGet request = new HttpGet(url);
request.setHeader("Accept", "application/json");
response = client.execute(request);
EntityUtils.toString(response.getEntity(), standardCharsets.UTF_8.displayName());

The expected response after converting it to a String is as follows:

{"errors": ["permission denied"]}

This code was working fine until recently. But now the response body is somehow being modified to this:

{"errors":["1 error occurred:\n\t* permission denied\n\n"]}

I do not understand how the "1 error occurred" message is being inserted into the response body as the response from the same call in Postman gives me the appropriate response ie:

{"errors": ["permission denied"]}

And I've checked the code thoroughly and am certain that the "1 error occurred" message is not being inserted manually.

EDIT:

These were the response headers from Postman:

cache-control →no-store
content-length →33
content-type →application/json
date →Thu, 30 May 2019 06:52:33 GMT
status →403

And these were the response headers from the HttpClient call:

Cache-Control: no-store
Content-Type: application/json
Date: Thu, 30 May 2019 09:06:21 GMT
Content-Length: 60

The only difference is that the status code isn't being printed. But checking the status code through the response.getStatusLine().getStatusCode() yields 403 as well.

Looks like you are using Apache HttpClient, which does not modify responses this way. It's definitely the response generated by server. Check your configuration of request in Postman to see if there are any additional headers, that may alter server behavior.
