Fix upload photo

[manslaughter03]

Hi,

First thanks for the works.

I start to investigate upload photo bad request #281, i need this feature and not wanting to use another libray. So i try to fix this issue.

I got inspired by https://github.com/dilame/instagram-private-api/blob/master/src/repositories/upload.repository.ts#L18.

• I use the same endpoint /rupload_igphoto/${name} instead of /upload/photo/
• I add some headers, like : X-Instagram-Rupload-Params, Offset, X-Entity-Length.
• I use application/octet-stream as Content-Type
• The same for configure request i add some value in config

I add an example: examples/upload-photo/main.go, I have to update goinsta import, for test purpose i import my repository.

If you have time to review my code and test this fix in your environment.

Thanks.

Hi, I have applied goinsta like format and added uploadPhoto as a method to media.
See my latest commits:

Hi, i think we should take an io.Reader as parameter on uploadPhoto function, we should remove postPhoto and use only uploadPhoto ? Otherwise it's good idea to add switchCookiesBetweenDomains. I'm going to commit your changes in my fork and test it.

Hey,
uploadPhoto is not only used in uploading a new photo to feed, but also in changing profile picture, sending a new story, or sending someone a new photo message; as far as I know.
Therefore, I think it's better to have a single uploadPhoto function that accepts a file name, for a reader we have to read the file each time before passing it to uploadPhoto.

why this is needed?

[manslaughter03]

I add this random number to generate name of the upload (part of url) and then use as value of 'X-Entity-Name' header. I use the same range used by https://github.com/dilame/instagram-private-api/blob/master/src/repositories/upload.repository.ts#L20. When i listen instagram api call from app, the requested url for upload fit this generate string.

nitpick:
var buf bytes.Buffer

[manslaughter03]

It seems buf need to be initialize to be use as a reader
./media.go:960:71: cannot use buf (type bytes.Buffer) as type io.Reader in argument to http.NewRequest
