httprequest

问题 Scenario: The browser submits a HTTP request to a server. The user simultaneously clicks on a bookmark or on another link on the page resulting in a new request to the server. The server now sends back two HTTP responses (or the browser gets responses from two servers). How does the browser decide which of the responses to actually process? I know what will happen - am trying to understand why. Any references or websites that explain this would also be much appreciated. Thank you, vivek. Edit

问题 I read this question but it didn't answer my question. To me Headers and Parameters are both dictionaries with the difference that headers is [String : String] while Parameters is [String : AnyObject]? and so if your parameters are also Strings then you could send them within the headers (while using a 'x-' prefix to signify they aren't standard headers) which is a common but not good practice. Is that correct? Are there other difference between headers and parameters ? What kind of other non

问题 I was wondering if you can help me with a bug I ma having. I have a HTTP Manager I have created that helps me dealing with POSTing/GETing data from websites. It has worked fine until recently when I am trying to use a mixture of both. First loop round everything works, on the second loop it hangs on HttpWebRequest.GetRequestStream(). I have read all over the net and have found no real solution. Below are the codeblocks for the fetching/receiving: ASCIIEncoding encoding = new ASCIIEncoding();

问题 I try to parse data using json and AsyncTask . But am getting the error on these line: JSONObject json = jsonParser.makeHttpRequest(url_product_detials, "GET", params); this is my code: public class EditWatchListProducts extends Activity { EditText txtName; EditText txtPrice; Button btnSave; Button btnDelete; String pid; private ProgressDialog pDialog; JSONParser jsonParser = new JSONParser(); private static final String url_product_detials = "http://192.168.2.22/android_connect/get_product

问题 I am using Javascript (in the Google Apps Script Editor) to make HTTP requests to the Google Drive API. I've successfully made individual calls to the API, so I know my Oauth 2 works, but now I'm working on making a batch request. I will loop through each file, and make 2 API calls per file. My request: var newOwnerEmail = 'archive@test.com'; var newEditorEmail = 'admin@test.com'; var fileIds = ['a', 'b', 'c']; const boundary = 'testboundaryname'; const delimiter = "\r\n--" + boundary + "\r\n

问题 I'm trying to implement a simple HTTP endpoint for an application written in node.js. I've created the HTTP server, but now I'm stuck on reading the request content body: http.createServer(function(r, s) { console.log(r.method, r.url, r.headers); console.log(r.read()); s.write("OK"); s.end(); }).listen(42646); Request's method, URL and headers are printed correctly, but r.read() is always NULL. I can say it's not a problem in how the request is made, because content-length header is greater

问题 Is it possible to create a HTTP HEAD request with the new HttpClient in .NET 4.5? The only methods I can find are GetAsync , DeleteAsync , PutAsync and PostAsync . I know that the HttpWebRequest -class is able to do that, but I want to use the modern HttpClient . 回答1: Use the SendAsync method with an instance of HttpRequestMessage that was constructed using HttpMethod.Head . GetAsync , PostAsync , etc are convenient wrappers around SendAsync ; the less common HTTP methods such as HEAD ,

问题 If you do a simple index into Request's items via Request[key], it looks in 4 locations. What's the order? Someone makes a guess on that page at "Cookies, ServerVariables, Form and QueryString". Does anyone know for sure? Documentation would be a bonus :) 回答1: public string this[string key] { get; } Declaring Type: System.Web.HttpRequest Assembly: System.Web, Version=2.0.0.0 public string this[string key] { get { string str = this.QueryString[key]; if (str != null) { return str; } str = this

问题 I'm calling an API hosted on Apache server to post data. I'm using HttpWebRequest to perform POST in C#. API has both normal HTTP and secure layer (HTTPS) PORT on the server. When I call HTTP URL it works perfectly fine. However, when I call HTTPS it gives me time-out exception (at GetRequestStream() function). Any insights? I'm using VS 2010, .Net framework 3.5 and C#. Here is the code block: string json_value = jsonSerializer.Serialize(data); HttpWebRequest request = (HttpWebRequest)System

问题 Should the PATCH method return all fields of the resource in the response body? Or should it return only updated fields? I'm reading this For example, if it returns only updated fields, the user could know which fields were updated in the server, while the user updated some fields. **Users resource representations** name: string age: number createdon: date modifiedon: date PATCH /users/{userId} Request body { name: 'changedname', } Response body Case1 { name: 'changedname', age: 20, createdon
