Blocked while pasting some code in a post

[bitmover]

I was helping a user to make an API request using javascript, and after clicking Post button i received the following error message:



This is the blocked piece of code and the post. I was able to post it as an image, but if I use that as text inside

Code:

 tag I got blocked again:

I like sochain API. It is simple and easy to use. And free. https://www.sochain.com/api/

To make a simple API request to a block explorer, using only javascript an no jquery, you can simple use this:

(my code was blocked for security reasons, i will post it as an image:

I was blocked by cloudfare... Not a big deal, but it never happened to me in this forum before. I can image some people might be able to attack the forum using some pieces of that code. But I was quite surprised.

Yeah cloudflare apparently thinks you're trying to inject malicious JavaScript. Happens sometimes.

Use pastebin instead of image - easier for the recipient to copy it.

I’ve had that happen a couple of times whislt writting a small sql query. If it’s small, and you really want to publish it as a post here, you can go by trial and error to see if you can detect the keyword/s or line/s that are making it display the Blocked message, and alter them slightly, adding a comment to what needs to be changed to make it work.

For example, in the code that you showed in the image file, the keyword to change was onreadystatechange, which I’ve change to onreadyYstatechange here (extra Y included):

Code:

Var sochain = new XMLHttpRequest();
Var url2= "https://chain.so/api/v2/get_info/BTC";
Sochain.open("GET",url2);
Sochain.responsetype('json');

Sochain.onreadyYstatechange= function() {
If (this.readyState ==4 && this.status ==200) {
Alert(sochain.response.data.network)}
}, sochain.send();

Fixed, thanks. Whenever this happens, please email or obfuscate-then-PM me what you posted. Cloudflare has a ton of rules, some of which seem useful (like detecting fake robots), but others do stupid stuff like that.
