xmlhttprequest

问题 I make a firefox extension that get all the request url's and displays them. But the code only works if I paste it in the console. when the extension loads it doesn't show any error, it seems like it just won't run here is the full code xhrScript.js (function(){ const proxiedOpen = XMLHttpRequest.prototype.open; window.XMLHttpRequest.prototype.open = function ( _, url) { this.__URL = url; return proxiedOpen.apply(this, arguments); }; const proxiedSend = window.XMLHttpRequest.prototype.send;

问题 I was trying to modify the adblockplus code for testing purpose. I was modifying the code to send a http get request on a URL and get the final URL from the response. I tried using the below code, but the response doesn't contain the Location field in the header response. I am doing this within a firefox-extension, so I dont think cross-domain request would be any issue. Why is it that I am not able to fetch the Location field from the response? Is there a better way to accomplish this task ?

问题 On local testing server url have ssl certificate error so i have to disable ssl check. I have read many solutions on stackoverflow none of them helped. Problem is i can't make any change on server. So i want to know how to disable ssl check or is there any other api like fetch api or Retrofit for react native.? My fetch api code as follows fetch('https://example.com/logincheck', { method: 'post', headers: { 'Accept': 'application/json, text/plain,', 'Content-Type': 'application/json' }, body:

问题 On Chrome, I'm having no troubles making a cross domain request, however on Firefox (Ubuntu 14.04), I get an error that consists only of a colon on the line that calls for the xmlhttprequest. xmlhttp.open("GET", "http://x.x.x.x:xxxx/folder/file.xml", false); The error message is just ":". 回答1: Try Disabling AdBlock I was having a similar issue where all of my XMLHttpRequests were going through except for a few very specific ones where even minor URL changes fixed the problem. And the only

问题 I'm bound to use native javascript (although a jQuery solution can also work if I convert it to native javascript). Also, I have no handles to existing AJAX requests so I can't access them directly. I am searching for something like: var ajaxRequestsInProgress = document.getAllAjaxRunning(); ajaxRequestsInProgress[1].getStatus(); // will return the status of the request, for example so I can access this object and check / manipulate existing ajax requests. 回答1: This is, shall we say, a little

问题 Mixed content isn't blocked for potentially trustworthy origins, including IP addresses from 127.0.0.0 to 127.255.255.255. Can browsers be configured to block mixed content for such addresses? This would make local testing easier. 回答1: I have found no browser settings to treat potentially trusted domains as untrusted, BUT here are several options to make 127.0.0.1 and untrusted domains behave the same, or to generate a report of items that would normally generate a warning. XHR For XHR,

问题 I have an XHR response that looks something like this: [ [ "e33222", "1730-06-27", "Lewis Morris", [ "Edward Wynne; ", "William Bulkeley" ] ], [...] ] It is used to populate a table with var table = $('#mainTable').DataTable() table.rows.add(result) table.draw(); It all works great, except for an annoying comma added at the beginning of every subsequent sub-item (or, better, at the end of every first sub-item which has a following one, see "Edward Wynne; ", "William Bulkeley"). The end result

问题 I found an XHR request for a website, now I want to convert this request to corresponding python/requests code and struggled at how to parse the responseType to corresponding replacement code, here is the download script: const download = (url, params = {}, dowType, name, img, method) => new Promise((resolve, reject) => { const _tmpArr = Object.keys(params) || []; const _formData = new FormData(); _tmpArr.map(value => { if (params[value] || params[value] === 0 || params[value] === '') {

问题 My goal … is to have a web extension (in Firefox for now) that intercepts and modified XMLHttpRequests issues by a site as transparently as possible. Best case is that the extension is undetectable by the site even when explicitly looking for it. For example, I want to be able to automatically redact/replace critical data before it is send out or enforce caching of large images despite the original page disabling that explicitly. Original approach Use a background script and browser

问题 I'm trying to upload a file in my s3 bucket with a aws presigned-URL. Here is my js function function UploadObjectUsingPresignedURL() { var file = document.getElementById('customFile').files[0]; console.log(file); var xhr = new XMLHttpRequest(); xhr.open('PUT', 'hereMyPresignedURL', true); //xhr.setRequestHeader('Content-Type', 'image/jpeg'); xhr.onload = () => { if (xhr.status === 200) { console.log('Uploaded data successfully'); } }; xhr.onerror = () => { console.log('Nope') }; xhr.send
