React access control allow origin5/1/2024 I don't really understand the mechanism that react-pdf uses to load the image and how that would be different from a regular HTML tag. Where to add Access-Control-Allow-Origin using ReactJS Ask Question Asked 7 years, 1 month ago. Ultimately, this image is hosted on an external server I have no access to, so I can't change the CORS settings in the server. I've tried the no-cache suggestions in #766 and other suggestions in the issues section, but I haven't found a solution. 2-set headers manually like this: resonseobject.header('Access-Control-Allow-Origin', '') resonseobject. You can also load the image with a regular HTML img tag, but when using the Image tag from react-pdf it won't load due to CORS. there are 6 ways to do this in React, number 1 and 2 and 3 are the best: 1-config CORS in the Server-Side. You can load the image by copying the url in your web browser on a new tab. It's a technology that allows your web app to break free from the restrictions of the Same Origin Policy, which is a security measure that prevents resources from different origins from interacting with each other. The image loads fine in my HTML using an img tag, but when I try to load it in react-pdf I get the following errorĪccess to XMLHttpRequest at '' from origin ' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. I want to know how set Access-Control-Allow-Origin in axios post method at reactJS or react-native environment I use CORS Add-ons and it works but I want to set it in the header too, I try these ways but none of them does not work. I need to load an image hosted in an external domain I have no access to.
