add_post()
|
||||
Adds a post to the database.
|
||||
Parameters
|
||||
* login: login
|
||||
* password: password
|
||||
* file: file as a multipart form
|
||||
* source: source url
|
||||
* title: title **IGNORED**
|
||||
* tags: list of tags as a string, delimited by whitespace
|
||||
* md5: MD5 hash of upload in hexadecimal format
|
||||
* rating: rating of the post. can be explicit, questionable, or safe. **IGNORED**
|
||||
Notes
|
||||
* The only necessary parameter is tags and either file or source.
|
||||
* If you want to sign your post, you need a way to authenticate your account, either by supplying login and password, or by supplying a cookie.
|
||||
* If an account is not supplied or if it doesnt authenticate, he post will be added anonymously.
|
||||
* If the md5 parameter is supplied and does not match the hash of whats on the server, the post is rejected.
|
||||
Response
|
||||
The response depends on the method used:
|
||||
Post
|
||||
* X-Danbooru-Location set to the URL for newly uploaded post.
|
||||
Get
|
||||
* Redirected to the newly uploaded post.
