假设我有这个结构，它在给用户的 typedef struct {
cmd cmd; /// The processed command in each pipe stage
intt src1;
int src2; /// Actual value of src2 (considering forwarding mux, etc.)
} PipeStage;
头文件中定义：
sim.c现在假设我想在 typedef struct pipeStage{
cmd cmd;
pc_t PCofCmd;
int src1;
int src2;
int dstVal;
} PipeState;
文件中展开它的字段..我该怎么做？
import json
import requests
from bs4 import BeautifulSoup
from urllib.request import urlopen
import urllib.request
session = requests.Session()
session.cookies.get_dict()
url = 'http://www.citydis.com/'
headers = {'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/39.0.2171.95 Safari/537.36'}
response = session.get(url, headers=headers)
soup = BeautifulSoup(response.content, "html.parser")
metaConfig = soup.find("meta", property="configuration")
metaConfigTxt = metaConfig["content"]
csrf = json.loads(metaConfigTxt)["pageToken"]
jsonUrl = "https://www.citydis.com/s/results.json?&q=London& customerSearch=1&page=0"
headers.update({'X-Csrf-Token': csrf})
response = session.get(jsonUrl, headers=headers)
print(response.content)
甚至可能吗？

，其中一个（或多个）字段属于另一个struct（s）类型：
struct注意
如果字段的顺序很重要且typedef struct {
cmd cmd; /// The processed command in each pipe stage
int src1;
int src2; /// Actual value of src2 (considering forwarding mux, etc.)
} PipeStage;
typedef struct pipeStage{
// cmd cmd;
// int src1;
// int src2;
PipeStage stage; // or it might be a pointer: PipeStage *p_stage;
pc_t PCofCmd;
int dstVal;
} PipeState;
应该在pc_t PCofCmd之后，那么您没有太多选择，只能按原样定义新的cmd cmd;：
struct
