从线程名获取pid

可以通过以下方式从线程名获取pid:
1. 获取当前进程的所有线程信息:
```python
import psutil
pid = os.getpid()
process = psutil.Process(pid)
threads = process.threads()
```
2. 遍历所有线程,查找指定线程名的线程:
```python
thread_name = "my_thread_name"
for thread in threads:
if thread.name() == thread_name:
thread_pid = thread.id
break
```
3. 如果找到了指定线程名的线程,则可以通过 `thread.id` 获取该线程的pid。如果没有找到,则 `thread_pid` 值为 `None`。
完整代码示例:
```python
import os
import psutil
def get_pid_by_thread_name(thread_name):
pid = os.getpid()
process = psutil.Process(pid)
threads = process.threads()
thread_pid = None
for thread in threads:
if thread.name() == thread_name:
thread_pid = thread.id
break
return thread_pid
```
调用示例:
```python
thread_name = "my_thread_name"
thread_pid = get_pid_by_thread_name(thread_name)
print("Thread name: {}, PID: {}".format(thread_name, thread_pid))
```
