Step 5: "code on demand teach [sic] clients how to behave in specific situations that were not foreseen, i.e. a new media type definition."

第五步：“通过应变能力强的代码去指导用户如何应对特定的从未遇见过的媒体类型，比如新出现的媒体类型定义。”

With code generation, you can also build validation into the constructed classes, either automatically checking values when they are set or checking validity on demand.

用代码生成，您还可以将验证构建进所构造的类中，从而要么自动检查值(当设置好它们时)，要么按照需要检查有效性。

According to the system's practical demand, the thesis designs the key techniques including fleetly logging, bar code management and so on.

并结合系统的实际需求设计了包含快速录入、条码管理等一系列的关键技术。

You can prevent this vulnerability by ensuring that on-demand scripts are validated and that content generated from the scripts is encoded properly to prevent execution of malicious code.

通过确保按需脚本被验证并确保从那些脚本生成的内容被适当编码以阻止恶意代码的执行，您可以避免这类漏洞。
