http-status-code-400

问题 I am trying to do a payment gateway integration using mvc4 in razor. In that i need to call a page with prefilled post form. Using the below method, I am forming the post method form: private static string PreparePOSTForm(string url, System.Collections.Hashtable data) // post form { //Set a name for the form string formID = "PostForm"; //Build the form using the specified data to be posted. StringBuilder strForm = new StringBuilder(); strForm.Append("<form id=\"" + formID + "\" name=\"" +

问题 I read What HTTP status response code should I use if the request is missing a required parameter? but it did not specifically ask about headers and there didn't seem to be a consensus. The context of this question assumes successful authentication. I'm currently favoring either a 400 (though that doesn't feel right because this isn't really a case of "malformed syntax") or 403. Given 403's description: The server understood the request, but is refusing to fulfill it. Authorization will not

问题 I'm trying to post data to website. It is login operation. I check form data hidden tag etc. In form data there is a hidden input _RequestVerificationToken. That's why first, I made get request to parse _RequestVerificationToken and for headers. StringRequest _StringRequest = new StringRequest(Request.Method.GET, url, new Response.Listener<String>() { @Override public void onResponse(String response) { //Parsing Process } }, new Response.ErrorListener() { @Override public void onErrorResponse

问题 Recently, i've been receiving 400 errors from my reactJS service urls, but I don't receive them on my other microservices. Here is what I tried: Looking into express to find out if 400 errors are coming from there, no success. Digging into react code, no 400 errors should be coming from there. Looking into the chrome console.... but it has nothing. It doesn't even look like i'm receiving any logs on my server so it's like it never hit, so no logs there. My node version is 10.15.3 but all my

问题 I have a WCF service that has been working fine for some time now, and I decided to add something to it. All of the old stuff works just as it should and the new stuff works for smaller transfers from the client to the host. However, it blows up with a "(400) Bad Request" when the client tries to send large strings to the host. Without changing anything, the host can send items that are just as large or larger to the client with no problem. I've looked around on here and other sites, and

问题 I need help creating a POST request to my Java Spring Restcontroller. This is my controller - @RestController @RequestMapping("hedgesimulator/") public class HedgeSimulatorController { @RequestMapping(value = "hedgesim/", method = RequestMethod.POST) @ResponseBody public HedgeSimulatorLog putHedgeSimulation( @RequestBody HedgeSimulatorLog hedgeSimulatorLog) { System.out.println(hedgeSimulatorLog.toJsonString()); return hedgeSimulatorLog; } } I am using Chrome's "Advanced Rest Client" Plugin

问题 How to catch 400 header and process error callback on jsonp request? Or it's a bug? Here is an example: http://jsfiddle.net/pLuPb/ Neither error, neither complete is triggered? How to catch error? I'm cursed? Last week i'm getting this kind of problems... :D Guess i'll have to report this one to jQuery tracker. Thanks ;) 回答1: jsopn is not regular ajax request, it actually creates a script tag in ur DOM that's the reason jsonp response data is in format abc_FunctionName(data) , and you gat get

问题 In jQuery I want to fetch some data from facebook using the $.getJSON() method, but if the token is invalid, Facebook is returning the 400 status. How I can catch the error in $.getJSON() instead of $.ajax() ? 回答1: I think this will work for you $.getJSON("example.json", function() { alert("success"); }) .success(function() { alert("success 2"); }) .error(function() { alert("error occurred "); }) .complete(function() { alert("Done"); }); 回答2: The jquery Ajax docs offer two solutions, the

问题 I've got an ArticleFormModel containing data sent by normal html form which is injected by Spring using @ModelAttribute annotation, i.e. @RequestMapping(value="edit", method=RequestMethod.POST) public ModelAndView acceptEdit(@ModelAttribute ArticleFormModel model, HttpServletRequest request, BindingResult errors) { //irrelevant stuff } Everything works perfectly fine up to some point. The problem is that the ArticleFormModel contains a double field ( protected , set using normal setter).

问题 I kept getting <Response [400]> in my terminal while running the script.
