HTTP multipart-mixed POST (for a UPS Package Level Detail PLD Request)
See more HTTP Examples
Demonstrates how to create a POST for a UPS Package Level Detail PLD Request. The request must be a multipart-mixed request having two sub-parts. The first is a application/x-www-form-urlencoded with name=value URL encoded pairs. The second is a application/x-ups-binary containing a UPS PLD request.The HTTP request created by this example looks like this:
POST /hapld/tos/kdwhapltos HTTP/1.1 Content-Type: multipart/mixed; boundary=------------050801040202040701030308 Host: domain Content-Length: 658 --------------050801040202040701030308 Content-type: application/x-www-form-urlencoded Content-length: 134 AppVersion=1.0&AcceptUPSLicenseAgreement=YES&VersionNumber=V4R1&UserId=myUser&Password=myPassword&ResponseType=application/x-ups-pld --------------050801040202040701030308 Content-type: application/x-ups-binary Content-length: 721 020094 2014041500000594196532600 000000001*AAV0Y203 DE 5941965326000001*BA1ZV0Y2036650001829 00001+0000000000000012 +0000000000000000KGS07COL10 3CMEUR000001*CA18TC239 AOK Bahnhofstr.

// method is called.
