问题 Lets say we have a web page with a search input form, which submits data to server via HTTP GET. So that's mean server receive search data through query strings. User can see the URL and can also initialize this request by himself (via URL + Query strings). We all know that. Here is the question. What if this web page submits data to the server via HTTP POST? How can user initialize this request by himself? Well I know how to capture HTTP POST (that's why network sniffers are for), but how

问题 What is the difference between PUT, POST and PATCH methods in HTTP protocol? 回答1: POST HTTP.POST can be used when the client is sending data to the server and the server will decide the URI for the newly created resource.

问题 I need to open a JSF page in a new window by POST on click of a <h:commandButton> . I know I can acheive this using the JavaScript. But I would like to achive this using JSF and not JavaScript.

问题 I would like to submit some information collected from user during Inno setup installation to our server via POST. Obvious solution would be to include an .exe file that the setup would extract into temporary location and launch with parameters. However, I'm wondering - is there is any easier/better way? 回答1: Based on jsobo advice of using WinHttp library, I came with this very simple code that does the trick. Say, you want to send serial number for verification just before the actual

问题 I already have a sub class of Request that is used for http post to the server. The problem is, I have no idea on how can I add a parameter for a file. Posting string to the server is easy. but I need to add file as a different parameter.

问题 I know it is pretty simple to add a certificate to a HttpWebRequest. However, I have not found a way to do the equivalent using WebClient. Basicly, I want to send out a POST with a specific certificate using WebClient. How would you accomplish this exact code using WebClient: var request = (HttpWebRequest) WebRequest.Create("my-url"); request.Method = "POST"; request.ClientCertificates.Add(new X509Certificate()); //add cert 回答1: You must subclass and override one or more functions. class
