HTTP Post

HTTP Post uploads a file to a website, using HTTP[S] with the POST verb. POST is the mechanism used by most websites that accept browser-based uploads.

Use this script like a destination, as a per-file process. Typically you would use this in a task with one or more sources.

Input Parameters

• HTTP_URL (Required) - The URL to post to; for example, https://myserver/cust/upload.aspx. May include macros.
• HTTP_IgnoreCertProblems - Whether to ignore problems with the remote server certificate (such as signer not trusted). Default is False.
• HTTP_User - The username, for HTTP authentication.

  Note: If the website uses form-based authentication rather than HTTP authentication, this script does not work.

• HTTP_Password - The password, for HTTP authentication.
• HTTP_DestFilename - The destination filename. If not specified, the original filename is used.
• HTTP_FileFormField (Required) - The name of the form field for the file contents. Can include macros.
• HTTP_ExtraFields - The names and values of optional extra form fields to be provided along with the POSTed file. This is very application-specific. The format is a string like fldname1=value1|fldname2=value2|... Can include macros.
• HTTP_MaxFileSizeMB - If a file is larger than this (MB), then skip that file and signal an error. Default 100; max value 500.

Notes

HTTP Post works only when the website requires either no authentication, or HTTP authentication.

HTTP Post does not work for websites that require the user to sign on via a web form to authenticate.

This script is not suitable for files larger than a few dozen megabytes, because it loads the entire file into memory before saving it.
