我正在尝试使用psutil获取进程列表及其cpu使用情况,我以管理员身份运行脚本,遇到进程DymoPnpService.exe时失败,可能是什么问题？
import psutil
def process():
plist = psutil.get_process_list()
plist = sorted(plist, key=lambda i: i.name)
for i in plist:
print i.name, i.get_cpu_percent()
def main():
process()
main()
AcroRd32.exe 0.0 AcroRd32.exe 0.0 DymoPnpService.exe
Traceback (most recent call last):

API 服务器接收带有这些参数的请求，即邮政编码和房屋

但是，从 API 网关到 Lambda 代理的测试不返回值
https://xxxxxxxxxx.execute-api.eu-west-1.amazonaws.com/Test/getaddressproxy?postcode=XX2YZ&house=123
我认为问题在于 lambda 函数没有将查询字符串参数传递给 API 服务器。
知道如何将查询字符串参数传递给请求对象吗？
代码：
from __future__ import print_function
import json
import urllib2
import ssl
print('Loading function')
target_server = "https://api.domain.com"
def lambda_handler(event, context):
print("Got event\n" + json.dumps(event, indent=2))

ctx.check_hostname = False
ctx.verify_mode = ssl.CERT_NONE

print(event['path'])
print(event["queryStringParameters"])

我在程序中的一个函数检查哈希文件的md5sum
def check():
print "checking integrity status.."
md5 = subprocess.Popen(["md5sum", "-c", hashfile],shell=False, stdout=subprocess.PIPE)
#fopen = open(basefile, "r")
for f in md5.stdout.readlines():
fc = f.rstrip("\n")
sys.stdout.write("\rChecking..." + fc)
sys.stdout.flush()
现在发生的事情是整个命令首先执行然后使用md5.stdout.readlines从md5进行循环读取,因此它不是动态的,即我执行命令时没有得到输出....有没有办法我可以在命令执行时获得输出...
修复使用glglgl的答案:
def check():
print "checking integrity status.."
md5 = subprocess.Popen(["md5sum", "-c", hashfile],shell=False, stdout=subprocess.PIPE)
#fopen = open(basefile, "r")
fc = "NULL"
i = 0
for f in iter(md5.stdout.readline, ''):
k = fc
fc = f.rstrip("\n")
if "FAILED" in fc:
print fc
i = i + 1
sys.stdout.write("\rChecking... "+ str(i)+ " " + …这个bash脚本可以捕获数据通过STDIN传递时设置的所有环境变量,例如:
echo "Hello" | ./script.sh

exit 1
它有什么方法我可以在python中做同样的事情？
解决:
这是由此产生的python版本..

log = os.environ
data = open("/tmp/capture.log", "a")
for key in log.keys():
data.write((key))
data.write(" : ")

data.write("\n")
data.close()
