httprequest

问题 I'm using Ruby 1.9.3 and need to GET a URL. I have this working with Net::HTTP , however, if the site is down, Net::HTTP ends up hanging.

问题 I have an Android application from which I want to upload some data to a database on my web server.

How do I make sure that only I can call this? I don't want people to sniff up the URL and call it outside my application. Thanks 回答1: Use a simple static token to identify the client is yourself or in an

问题 With Postman, I can attach files in requests with form-data, I can also send nested JSON object in raw format, but how can I do both: sending nested-structure data with file, e.g: "data": { "normal_fields": { "field1": "value1", "field2": "value2" }, "image_file": <file> } 回答1: Try setting values like below and choose file to upload. 回答2: It didn't worked for me like that.

问题 I am running JMeter and I want a count of all the failed requests that either timed out, or, just plain failed. I see that some of the listeners show that there have been failures, but none see to have a field that displays the total number of failed requests versus successful requests. Does anyone know how I can easily get this data without having to count each failure by hand? 回答1: Add timeout to your sampler Add assertions on code and response content Use aggregate report You should have

问题 I'm developing Java Servlets. At the point of checking whether a user is logged in, I want to check if the HTTP request has a valid session. For checking that, I have 2 possibilities: (1) protected void processRequest(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { HttpSession session = request.getSession(false); if (session != null) { // user is logged in ... } } Since I pass false as an argument, there is no new session created if there is no

问题 "Simple" question. Is it better to use large spritesheets for site elements than using multiple images? I mean,do the additional CSS image manipulation (background positioning a large image and cropping it) compensate for the fewer HTTP image requests? 回答1: The number of concurrent HTTP/1 connections to a host is limited to about 6.
