使用python请求传递参数时出现的问题

import requests

url = "https://example.com/api"
params = {
    'key1': 'value1',
    'key2': 'value2'
}

response = requests.get(url, params=params)
print(response.text)

import requests
import json

url = "https://example.com/api"
data = {
    'key1': 'value1',
    'key2': 'value2'
}

headers = {
    'Content-Type': 'application/json'
}

response = requests.post(url, data=json.dumps(data), headers=headers)
print(response.text)

from urllib.parse import urlencode

params = {
    'key1': 'value1',
    'key2': 'value with spaces'
}

encoded_params = urlencode(params)
url = f"https://example.com/api?{encoded_params}"

response = requests.get(url)
print(response.text)

try:
    response = requests.get(url, params=params)
    response.raise_for_status()  # 如果响应状态码不是200，会抛出异常
except requests.exceptions.HTTPError as errh:
    print ("Http Error:",errh)
except requests.exceptions.ConnectionError as errc:
    print ("Error Connecting:",errc)
except requests.exceptions.Timeout as errt:
    print ("Timeout Error:",errt)
except requests.exceptions.RequestException as err:
    print ("Something Else:",err)
