Ajax cross-domain access, the options preview request cannot access through the background, cause errors, such as return 403500


Online to find a lot of, is the background makes the options request directly pass away, this let a person very uncomfortable, like, predecessors in order to let you live in safety door, made a door for you, you don't know the key, so open the door,

So want to ask, if there is a know "keys", please inform, thank you very much

Can consult CROS, json
Json is not recommended, however, can be to get request way

The emergence of the options, is the request cross-domain and brought the custom of the header; If don't want to let the back-end to modify the original code or the backend is third-party interface cannot be modified; You can only build on their server proxy server;

CodePudding user response:

Cross-domain, generally not framework development suggest using nginx proxy cross-domain (my blog posts), as well as webpack framework recommends own proxy (has), json is in itself a get request for temporary, there is a lot of limitations, is not suitable for development
