httprequest

问题 How can I make an HTTP request from within Node.js or Express.js? I need to connect to another service. I am hoping the call is asynchronous and that the callback contains the remote server's response. 回答1: Here is a snippet of some code from a sample of mine. It's asynchronous and returns a JSON object. It can do any form of GET request. Note that there are more optimal ways (just a sample) - for example, instead of concatenating the chunks you put into an array and join it etc... Hopefully,

问题 GET : $.get(..) POST : $.post().. What about PUT/DELETE ? 回答1: You could use the ajax method: $.ajax({ url: '/script.cgi', type: 'DELETE', success: function(result) { // Do something with the result } }); 回答2: $.ajax will work. $.ajax({ url: 'script.php', type: 'PUT', success: function(response) { //... } }); 回答3: We can extend jQuery to make shortcuts for PUT and DELETE: jQuery.each( [ "put", "delete" ], function( i, method ) { jQuery[ method ] = function( url, data, callback, type ) { if (

问题 In Firefox, I use Firebug which allows me to view every http request my ajax calls are making. I've switched over my development to Chrome and am liking it so far. My only complaint, however, is that the developer tools don't seem to allow you to view each ajax request. I've had it happen once where the Resources panel showed multiple requests to the same resource, but it's only done it once and never again. Is there a way to reliably see every http request that a page is making through

问题 I tried the sample provided within the documentation of the requests library for python. With async.map(rs) , I get the response codes, but I want to get the content of each page requested. This, for example, does not work: out = async.map(rs) print out[0].content 回答1: Note The below answer is not applicable to requests v0.13.0+. The asynchronous functionality was moved to grequests after this question was written. However, you could just replace requests with grequests below and it should

问题 I'm trying to figure out how to POST JSON from Android by using HTTPClient. I've been trying to figure this out for a while, I have found plenty of examples online, but I cannot get any of them to work. I believe this is because of my lack of JSON/networking knowledge in general. I know there are plenty of examples out there but could someone point me to an actual tutorial? I'm looking for a step by step process with code and explanation of why you do each step, or of what that step does. It

问题 I am using the following method to output objects with their properties. It works great with most objects, but throws when I pass a HttpRequest object. public static string ConvertToXML(object obj) { if (!obj.GetType().IsPrimitive && obj.GetType() != typeof(String) && obj.GetType() != typeof(Decimal)) { List<string> properties = new List<string>(); foreach (PropertyDescriptor descriptor in TypeDescriptor.GetProperties(obj)) { string name = descriptor.Name; object value = descriptor.GetValue

问题 I use a .htaccess file to redirect all requests to the same index.php . From there, I decide what to do depending on URL of the incoming request. For now, I map the request URL to directory structure relative to a source folder, so that example.com/user/create maps to source/user/create/index.php . The file located there can handle the request as needed, and generate HTML output. But that doesn't work for static assets, the browser may request. So my idea is to find out whether a request URL

问题 Hello everybody and thanks for your help, I am developing a web application using JSF and for security reasons i need to capture the user's IP when he does the log in.
