Python使用POST方法发送HTTP请求的15个示例（基于requests）

以下是使用requests库调用HTTP接口进行POST请求的15个示例：

1. 发送简单的POST请求：

import requests

payload = {
            'key1': 'value1', 'key2': 'value2'}
response = requests.post('http://example.com', data=payload)
print(response.text)

2. 发送JSON格式的POST请求：

import requests
import json

payload = {
            'key1': 'value1', 'key2': 'value2'}
response = requests.post('http://example.com', json=json.dumps(payload))
print(response.text)

3. 发送XML格式的POST请求：

import requests

payload = '<xml><key1>value1</key1><key2>value2</key2></xml>'
response = requests.post('http://example.com', data=payload, headers={
            'Content-Type': 'application/xml'})
print(response.text)

4. 发送文件的POST请求：

import requests

files = {
            'file': open('file.txt', 'rb')}
response = requests.post('http://example.com', files=files)
print(response.text)

5. 发送二进制数据的POST请求：

import requests

data = b'\x00\xff\x00\xff'
response = requests.post('http://example.com', data=data, headers={
            'Content-Type': 'application/octet-stream'})
print(response.text)

6. 发送多个文件的POST请求：

import requests

files = [('file1', open('file1.txt', 'rb')), ('file2', open('file2.txt', 'rb'))]
response = requests.post('http://example.com', files=files)
print(response.text)

7. 发送表单的POST请求：

import requests

payload = {
            'key1': 'value1', 'key2': 'value2'}
response = requests.post('http://example.com', data=payload, headers={
            'Content-Type': 'application/x-www-form-urlencoded'})
print(response.text)

8. 发送JSON格式的POST请求并带认证信息：

import requests
import json

payload = {
            'key1': 'value1', 'key2': 'value2'}
auth = ('user', 'password')
response = requests.post('http://example.com', json=json.dumps(payload), auth=auth)
print(response.text)

9. 发送JSON格式的POST请求并带Headers：

import requests
import json

payload = {
            'key1': 'value1', 'key2': 'value2'}
headers = {
            'Content-Type': 'application/json'}
response = requests.post('http://example.com', json=json.dumps(payload), headers=headers)
print(response.text)

10. 发送JSON格式的POST请求并带Cookies：

import requests
import json

payload = {
            'key1': 'value1', 'key2': 'value2'}
cookies = {
            'name': 'value'}
response = requests.post('http://example.com', json=json.dumps(payload), cookies=cookies)
print(response.text)

11. 发送JSON格式的POST请求并设置超时时间：

import requests
import json

payload = {
            'key1': 'value1', 'key2': 'value2'}
timeout = 10
response = requests.post('http://example.com', json=json.dumps(payload), timeout=timeout)
print(response.text)

12. 发送JSON格式的POST请求并设置代理：

import requests
import json

payload = {
            'key1': 'value1', 'key2': 'value2'}
proxies = {
            'http': 'http://proxy.example.com:8080'}
response = requests.post('http://example.com', json=json.dumps(payload), proxies=proxies)
print(response.text)

13. 发送JSON格式的POST请求并设置SSL认证：

import requests
import json

payload = {
            'key1': 'value1', 'key2': 'value2'}
response = requests.post('https://example.com', json=json.dumps(payload), verify=True)
print(response.text)

14. 发送JSON格式的POST请求并禁用SSL认证：

import requests
import json

payload = {
            'key1': 'value1', 'key2': 'value2'}
response = requests.post('https://example.com', json=json.dumps(payload), verify=False)
print(response.text)

15. 发送JSON格式的POST请求并设置SSL认证证书：

import requests
import json

payload = {
            'key1': 'value1', 'key2': 'value2'}
cert = ('client.crt', 'client.key')
response = requests.post('https://example.com', json=json.dumps(payload),cert=cert)
print(response.text)
