httprequest

问题 I'm trying to get the source of an HTML file with an HTTP request in node.js - my problem is that it returns data twice. Here is my code: var req = http.request(options, function(res) { res.setEncoding('utf8'); res.on('data', function (chunk) { if(chunk.length > 1000) { console.log(chunk.length); } }); req.on('error', function(e) { console.log("error" + e.message); }); }); req.end(); This then returns: 5637 3703 The hell! When I just console.log(chunk), it returns all the data as if it were

问题 Now on my Flutter application I am trying to do the same thing: after run this App... {"error":true,"message":"Sorry, Auth key is not defined"} My code is: class Post { String username; Post({this.username});// call post API factory Post.fromJson(Map<String, dynamic> json) { return Post(username: json['username']); } Map toMap() { var map = new Map<String, dynamic>(); map["username"] = username;// post username return map; } } class MyApp extends StatelessWidget { final Future<Post> post;

问题 We had a form which was submitting the data to a page in a new tab. Like, <form name='formOne' action='/action.cfm' method='post' target='_blank'> <input type='hidden' name='employee' value='{"first_name": "test","last_name":"name"}' /> <input type='hidden' name='contact' value='{"phone": "1233214090","fax":"1098760982"}' /> <input type="submit" /> </form> But now "action.cfm" page is expecting a JSON value in http request body. Like { "employee": { "first_name": "test", "last_name": "name" }

问题 Is there any difference between doing a "GET" request (type URL and Enter ) compared to simply refreshing ( Ctrl R ) the page? 回答1: No, it is not simply a get request, because on a page that you've POSTed to (from a separate form), the browser will confirm with you that you want to refresh the page because it is a POST request. As for your question, you'll need to provide specifics for debugging purposes. 回答2: It is simply telling the browser to repeat the page load, which implies repeating

问题 I want to have my Android app track its own data usage. I can get the Content-Length of the HTTP response, but I can't find how to get the size of the request before it's sent out. All the requests (GET, POST, PUT, etc) are instances of HttpUriRequest . Thanks 回答1: All requests with content should be a subclass of HttpEntityEnclosingRequestBase . HttpUriRequest req = ...; long length = -1L; if (req instanceof HttpEntityEnclosingRequestBase) { HttpEntityEnclosingRequestBase entityReq =

问题 Trying to find a work around for users who have IE 7. Basically in my client-side javascript application the below code makes a httprequest to a server running node.js and I get a succesful connection if the client has IE8 but it's unsuccesful in IE7. Thoughts? var myxmlhttp; doRequest(); function doRequest() { var url = "http://someserver:8000/" + username; myxmlhttp = CreateXmlHttpReq(resultHandler); if (myxmlhttp) { XmlHttpGET(myxmlhttp, url); } else { alert("An error occured while

问题 I'm trying to send a list of datetimes to the client by JSON formatted as its locale. So the main issue is actually trying to get the locale of the client. I tried to use request.META['LC_TIME'] (which seems to be the client's prefered locale for dates and times) This key is here in development but not in production. KeyError: 'LC_TIME' How can it be explained ? Am I on the right track ? 回答1: First, let's determine what you mean under 'Production environment'. Under DEV environment, the

问题 Okay. I've been working with raw HTTP Request and found out that I can post the Raw HTTP Response into NSLog and i've nearly cracked the raw HTTP Request into NSLog. I'm just abit stuck now. Code Example NSString *CurrentWebURL = webView.request.URL.absoluteString; NSURLSession *session= [NSURLSession sessionWithConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]]; [[session dataTaskWithRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:CurrentWebURL]]

问题 so, I have page doing a number of ajax and jsonp(i.e. injection) to get data. I would like to know how to find out the request URL I have made without using debugging tools, like firebug. etc. i.e. the history of GET request of the browser. Thanks 回答1: For the most part, browsers do NOT log a history of their HTTP GET requests. Also, if you're using ajax, you're probably doing HTTP POST requests as well. You don't have to use an in-browser tool like Firebug, but you will need some tool to

问题 I am trying to use the Dart HttpClient class (io library / server-side!) and I can not think how to do the EQUIVALENT of the Dart (client-side) call to setRequestHeader. Specifically I want to set "Content-type" to "application/json" as per this line (from Client-side): request.setRequestHeader("Content-type", "application/json"); I'm using the format: new HttpClient().postUrl(Uri.parse(url)) .then((HttpClientRequest request) => request.close()) .then((HttpClientResponse response) => response
