This is a common source of confusion, so I wanted to go into a bit more detail. I have a full working demo in this Gist, and you can view a live version of it thanks to RawGit. Here’s the relevant portion of the service worker code inline, for illustrative purposes: self.addEventListener(‘fetch’, event => { … Read more
This is an API issue, you won’t get this error if using Postman/Fielder to send HTTP requests to API. In case of browsers, for security purpose, they always send OPTIONS request/preflight to API before sending the actual requests (GET/POST/PUT/DELETE). Therefore, in case, the request method is OPTION, not only you need to add “Authorization” into … Read more
I do something like this in my development environment by configuring Apache on port 80 as a proxy for my application server on port 8080, with the following Apache config: NameVirtualHost * <VirtualHost *> <Proxy http://127.0.0.1:8080/*> Allow from all </Proxy> <LocationMatch “/myapp”> ProxyPass http://127.0.0.1:8080/myapp ProxyPassReverse http://127.0.0.1:8080/myapp Header add myheader “myvalue” RequestHeader set myheader “myvalue” </LocationMatch> … Read more
RFC 2616 is obsolete, the relevant part has been replaced by RFC 7230. The NUL octet is no longer allowed in comment and quoted-string text, and handling of backslash-escaping in them has been clarified. The quoted-pair rule no longer allows escaping control characters other than HTAB. Non-US-ASCII content in header fields and the reason phrase … Read more
Use Strings for your hash keys instead of Symbols. query = { “method” => “neworder”, “nonce” => 1404996028, “order_type” => “buy”, “quantity” => 1, “rate” => 1 } headers = { “key” => “8781974720909019987”, “sign” => “0a3888ac7f8e411ad73a0a503c55db70a291bfb9f9a47147d5200882674f717f6ede475669f3453” } HTTParty.post( “https://www.acb.com/api/v2/market/LTC_BTC/”, :query => query, :headers => headers ) It was probably only the headers that were … Read more
Easy, just use the HEAD method, instead of GET or POST: function UrlExists(url, callback) { var http = new XMLHttpRequest(); http.open(‘HEAD’, url); http.onreadystatechange = function() { if (this.readyState == this.DONE) { callback(this.status != 404); } }; http.send(); } This is just a short example to show how to use the HEAD method. Production code may … Read more
For people who still want an even more permissive posts, because the other answers were just not permissive enough, and they must work with google chrome for which * is just not enough: default-src * data: blob: filesystem: about: ws: wss: ‘unsafe-inline’ ‘unsafe-eval’ ‘unsafe-dynamic’; script-src * data: blob: ‘unsafe-inline’ ‘unsafe-eval’; connect-src * data: blob: ‘unsafe-inline’; … Read more
When creating your request use request.Header.Set(“key”, “value”): package main import ( “io” “log” “net/http” ) func main() { client := &http.Client{} req, err := http.NewRequest(“GET”, “http://httpbin.org/user-agent”, nil) if err != nil { log.Fatalln(err) } req.Header.Set(“User-Agent”, “Golang_Spider_Bot/3.0”) resp, err := client.Do(req) if err != nil { log.Fatalln(err) } defer resp.Body.Close() body, err := io.ReadAll(resp.Body) if err … Read more
This should be pretty close String dateString = “Wed, 09 Apr 2008 23:55:38 GMT”; SimpleDateFormat format = new SimpleDateFormat(“EEE, dd MMM yyyy HH:mm:ss zzz”); Date d = format.parse(dateString); SimpleDateFormat
For anyone else that comes across this post and might find it useful… There is actually nothing wrong with my code. I made the mistake of requesting client_credentials type access code instead of password access code (#facepalms). FYI I am using urlencoded post hence the use of querystring.. So for those that may be looking … Read more
