How to POST NON-JSON request using Apache HttpClient?

问题

I am to hitting an API which will return string data and as well I want to send data of string type(textfile in a paragraph).

You can use Apache httpcomponents, with http entities

Here is an example for sending a file in your POST request:

File file = new File("somefile.txt");
FileEntity entity = new FileEntity(file, ContentType.create("text/plain", "UTF-8"));        

HttpPost httppost = new HttpPost("http://localhost/action.do");
httppost.setEntity(entity);

If you want a text content, you can use StringEntity:

StringEntity myEntity = new StringEntity("something", ContentType.create("text/plain", "UTF-8"));
