How to read request method from response

[windwalker]

I'm writing a hook on fetch response. I need both the URL and the method of the request to decide whether the hook should be called or not.

However, in the response hook, I can only get URL. Do you know where could I get the method('post', 'get', 'put', etc.) that the request is using in the response hook?

fetchIntercept.register({
  response: function(response) {
      if(response.url === predefinedURL   &&   response.method /* I don't know how to get it */  === predefinedMethod) {
           //do something here
      }
  }
});

Many Thanks

This is currently not possible you can take a look at the angular $http inteceptors how they doing something like this.

Thanks. I guess the only way around is to proxy fetch. I end up writing some code like this:

window.fetch = (function(oldFetch) {
  if (oldFetch.__mocked__) {
        return oldFetch
  } else {
        var mock = function(url, config) {
              var custom = {url, config};
              return oldFetch(url, config).then(function(res) {
                    res.__params__ = custom;
                    return res;
             });
        mock.__mocked__ = true;
        return mock;
  }
})(window.fetch)
