為{幸葍}努か 提交于 2020-01-11 03:20:09

I think XhrIo should work because from my machine when I use any other rest client ,like Firefox browser app RESTClient or Chrome's Simple Rest Client , I can make POST request to the server and content type is application/json. But from my application I am unable to make a post. I am using the following code xhr = new goog.net.XhrIo; xhr.send('http://myhost:8181/customer/add','POST', goog.json.serialize(data)); If I leave the headers default, I

I am looking to convert them to GWT-RPC calls if that brings in performance improvement. I would like to know about pros/cons of each... Also any suggestions on tools to measure performance of Async calls... [A good article on various Server communication strategies which can be

与世无争的帅哥 提交于 2020-01-10 12:38:31
问题 I've got a JSON object that looks something like { "version" : "22", "who: : "234234234234" } And I need it in a string ready to be sent as a raw http body request. So i need it to look like version=22&who=234324324324 But It needs to work, for an infinite number of paramaters, at the moment I've got app.jsonToRaw = function(object) { var str = ""; for (var index in object) str = str + index + "=" + object[index] + "&"; return str.substring(0, str.length - 1); }; However there must be a
