问题 In a specific case I'd like to respond with a text/html content-type for an error as follows: class MyResource(Resource): def get(self): if some_condition: return 'bad argument', 400 The code above returns an application/json content-type: '"bad argument"' instead of a text/html content-type: 'bad argument' How can I force flask-restful to respond with text/html content-type? 回答1: You'll have to use flask.make_response() to return a 'pre-baked' response object: return flask.make_response('bad

问题 Spring 3.2.15, MVC-based REST API here ( not Spring Boot, sadly!). I am trying to implement an exception mapper/handler that meets the following criteria: No matter what happens (success or error), the Spring app always returns a response entity of MyAppResponse (see below); and In the event of processing a request successfully, return an HTTP status of 200 (typical); and In the event of processing a request and an exception occurs, I need to control the mapping of the specific exception to a

问题 I have a webform with a Download LinkButton , on the button's click event I'm fetching data and then generating an .XLSX file for download. During the generation of the file, Response.Clear() is called, Response.ContentType is set and eventually Response.End() is called. I need to display a spinner .gif during that operation.

问题 I have a java program, that calls a url. The response of url is a json/string. I have to write a program that fetches the data from this url, but I was wondering if there's a limit on the max size HTTP can pass back? I was going to write my server side (url) in such a way that it fetches all the data from db, but if there's a limit on the size I can fetch from server, I can do the read in batches also? So, is there a limit on the size of the response I can send over HTTP from server to my

问题 java.lang.IllegalStateException: Cannot call sendError() after the response has been committed As above mentioned I am getting an error in the line response .sendError() method.

Problem: When I try to get the contents of a specific local URL via file_get_contents() , it comes back as an empty string '' (length=0). What I've tried: $url = 'http://localhost/bbq/index.php/company/get/id/2131/return/json'; $results = file_get_contents($url); echo'<pre>Results:<br />',var_export($results),'</pre>'; When directly visiting http://localhost/bbq/index.php/company/get/id/2131/return

问题 This question already has answers here : HttpURLConnection.getResponseCode() throws IOException when code is known (2 answers) Closed 3 years ago .

So in this context why does it throw an IOException ? Am i missing something? 回答1: From javadoc: It will return 200 and 401 respectively. Returns -1 if no code can be discerned from the response (i.e

问题 I'm sending an http request using the http.request function, and I would like to read the whole http response like text; that is, the raw http protocol text. Is it possible? I've written the below code but it's not working. // Set up the request console.log('Sending request'); var post_req = http.request(post_options, function(res) { res.setEncoding('utf8'); console.log('Response statusCode: ' + res.statusCode); // res.on('data', function (chunk) { // console.log('Response: ' + chunk); // });

问题 I have a dedicated server with 256GB RAM 6 CPUs (12 Threads) on Hetzner, and it is located in Germany. I have CENTOS 7.5 . EA4 . My problem is with SSL.
