I am using Chrome 15 with Developer Tools to investigate HTTP POST requests. After sending a request, in the Network tab under Headers there is a section called Form Data. This section contains the post data nicely formatted. However: How do I get the source of the post data, i.e. the body of the request?
Currently, I use Firefox with Firebug to get that data, or I reconstruct the source from the formatted Form Data. Cumbersome...
Chrome 29–56, and possibly beyond
Finally (maybe already with version 28), it's simple. Just click on view source next to Form Data:
Also, at least in version 56, post data may be found in the Headers tab, under Request Payload.
Older versions
Chrome 27
Right click in the Name/Path panel in the Network tab.
Select: Copy all as HAR
In the Console, write har=, then paste the HAR, and hit return.
Count from the top the position of the request you are interested, starting at 0. Store the position in: pos
To get the post data source, execute: har.log.entries[pos].request.postData.text
even older:
Right click on the Name/Path of the entry in the Network tab.
Select: Copy entry as HAR
In the Console, write har=, then paste the HAR, and hit return.
To get the post data source, execute: har.request.postData.text
If there is a simpler way, I am happy to hear about it!
it's easier if you:
go to Network
click the entry you want to see the post for
click on the headers tab
scroll down to Form Data

I'm not familiar with web development but I believe this web page text content
https://almath123.github.io/semstyle_examples/
is made of two JSON files mentioned in it (semstyle_results.json and semstyle_results.json) and the JSON files are completely present in ram (If this is the correct term for referring to it) because when I disconnect the internet I can still browse the page and see the text content.
I want to download semstyle_results.json file. Is that possible? how can I do that?
Technically if you visit a website you're "downloading" the content. Your browser sends a request for information and a server responds by sending you the information. You're viewing that information locally. Dynamic sites poll or make further requests as you browse to keep the data updated and relevant, but it's sent to you.
If you want to easily download any of the content from the website, a simple way is to open up the development tools (CTRL + SHFT + I on windows for Firefox and Chrome), go to a source file and click save as. The network tab shows you requests that were made which includes not just files such as json but also the details of the request.
Here is a screenshot locating one of the json files in a Chrome-based browser (Brave)
The webpages may not always show that they will support json or xml return of data. For example if you inspect this webpage SEC EDGAR database using the method described above, it shows no json link but if you append index.json at the end of the link it will return the same data in json format or xml format, if you so please.
i.e: same website but with json endpoint
So it is always a good idea to see if the website hosts developer information. For example SEC EDGAR provides developer tools that mentions that the directory structure can be accessed via HTML, XML or JSON.

Problem:
Chrome caches too much data, so when i create entries like Post and Comment in my db, its isn't loaded, but all the existing entries are being displayed.
Chrome refuses to run through my script, and just displays it from cache, and therefor not showing the new entry.
I can solve this problem partly by using
Location.reload(true);
But when i create a post i route back to the overview of all posts, which isnt loaded properly from my API, since the new post isnt showing.
I route back to the overview with
Location.replace('../nyheder');
How do i clear cache while routing to another page?
I rather think it is an issue with your HTTP -mainly response- headers. The headers will tell Chrome whether to fetch new data or use its cache.
You should use
If-none-match
and
ETag
Headers.
I know from the Postman docs that I can open saved requests in a new tab either by creating a new tab before clicking on the saved request or with a keyboard shortcut, but I'm hoping there's a way to default Postman to always open requests in new tabs - like the standard functionality of most IDEs.
I frequently find that I've sent a request, then a second, different one and wish I could check something in the response for the first request, but it's no longer there, because the second request opened over the first.
Obviously if I know that I'm going to want the first response, I can explicitly save it, but that's quite cumbersome, and it's usually only after I've sent the next request that I realise I want to refer back.
I suspect the answer is probably to build muscle memory to always hold Ctrl + Shift when clicking a saved request, but it would be nice if there was a setting.
Just realised that this is now possible (or perhaps always was and I just missed it) - in the 'General' tab of the Settings dialog, under the heading 'REQUEST' is a switch for 'Always open requests in new tab'.
There is a setting for this. This image will help:
I'm using the Chrome Dev Tools, and I am digging through the network pane to look at an XHR response with the preview tab. I want to grab a specific object from the preview. But when I try to store as global variable by right clicking preview object, the temp variable created was null.
I find that rather strange since the data is in memory (otherwise it wouldn't be displayed at all). Here's an example of a rather large response array that I'm trying to get a specific object from.
To clarify, I can store a variable that appears in my console. But I can't store a variable from the preview pane of the network tab. Is there any feature of the Chrome Dev Tools I'm overlooking, or am I forced to console log my XHR response and pull the object from there?
I'd really rather not add any console.log() or other breakpoints into my code just to have to remove them later. Digging through the super-long raw JSON response is also not practical. I'm using Chrome 47 on Windows 7.
I can get it to work by going:
Right click on the array index
"Store as global variable"
Then from the console, typing:
copy(temp1);
And then it will be on the clipboard.
Maybe a bit late, but you could go to response tab, copy the response content and then in the console just paste it after :
var response = <<paste here>>
i cant tell by the screenshot but you can then type response.data[64]
This is regarding retrieving data from Mr.Robot
When I used the inspect element tool to investigate the traffic I was getting from the site via the network panel, here's a sample of the data I got
Does anyone know where I can find the data that corresponds to the video(tv episode)?
I saw that the file format of xhr represents the XMLHttpRequest so that is a combination of my browser requesting JSON, HTML, and XML from the web server? (Can someone confirm this as well)
I am trying to find a type that corresponds to one of these but having no luck.
I am doing this to enhance my knowledge of web and network engineering.
In the network tab, if you select to see the headers tab, you can see this information:
Request URL:http://api.massrelevance.com/usadigitalapps/mr-robot-tag-mrrobot.json?limit=5&since_id=1039088770827352555_891624285
Here, you can see it's a request to a JSON file. :D
EDIT: Try going to this URL when the video is not playing in the browser (for some reason, when I had the page loaded this was returning as blank):
http://api.massrelevance.com/usadigitalapps/mr-robot-tag-mrrobot.json?limit=5&since_id=1039263408306586885_20082880
That was the request mine was making. In there, you can find a video URL:
https:\/\/scontent.cdninstagram.com\/hphotos-xaf1\/t50.2886-16\/11765169_875397039210031_1586195986_n.mp4
Remove the \ and you'll see the video :D
