推荐答案

您需要将PDU解析为易于阅读的文本(如果存在).请考虑以下内容(如果在SMPP 3.3/3.4中)

http://en.wikipedia.org/wiki/SMPP [ http://www.spboss.com/download/%E8%BF%90% E8％90％A5％E5％95％86％E9％80％9A％E8％AE％AF％E5％8D％8F％E8％AE％AE/SMPP_v3_4_Issue1_2.pdf [

You need to parese the PDU back into human readable text if any exist. Consider the following (if it is in SMPP 3.3/3.4)

http://en.wikipedia.org/wiki/SMPP[^]

This will give you a little insight on how the PDU is constructed and can be deconstructed. Specifically, the link at the bottom of the page to the SMPP 3.4 specification (http://www.spboss.com/download/%E8%BF%90%E8%90%A5%E5%95%86%E9%80%9A%E8%AE%AF%E5%8D%8F%E8%AE%AE/SMPP_v3_4_Issue1_2.pdf[^]) will show you exactly how many bytes are for what.

Give it a try and post back if you get stuck in your programming.
