The above exception was the direct cause of the following exception:

可以在调用 load_module 的时候指定 trace_inst=True，这样会把模拟的指令输出出来，可以根据程序的实际执行情况定位问题；或者提供一下二进制文件，我看下什么情况。

佬，辛苦看下

我看了一下，你这个调用点是比较外层的一个位置，是构造一整个请求头，逻辑越复杂，调用遇到的问题就会越多，也会包含很多没必要的逻辑。一般建议尽量从更内层去调用，比如，调用某个字段的生成方法或者更核心的加密函数。

如何调用c函数，有没有例子可以参考

我的意思是，你主要目标是哪个字段，我们从字段层面来看问题
