It is possible to filter all har object and get only POST request/response? Maybe during initialized BrowserMobProxyServer is way to do it? I need to save har object into file and upload into har viewer.
Har har = proxyServer.getHar();
I don't know if you can do it with ProxyServer configuration, but I'm sure you can filter requests like this:
Har har = proxyServer.getHar();
try {
har.getLog().getEntries().removeIf(x-> !x.getRequest().getMethod().equals("POST"));
har.writeTo(new File("har.json"));
} catch (IOException e) {
e.printStackTrace();
}
It will create new file named "har.json" with only POSTs.
