authorization_page_sha1 = hashlib.sha1(authorization_page.encode('utf8')).hexdigest()

这是一个用于将字符串 `authorization_page` 进行 SHA1 哈希加密的 Python 代码,`encode('utf8')` 是将字符串编码为 UTF-8 格式。哈希加密是一种将任意长度数据映射为固定长度的技术,通常用于确保数据的完整性和安全性。`hexdigest()` 则将哈希结果转换为十六进制字符串形式。

micropython连接阿里云调用接口代码
以下是一个基于MicroPython的示例代码,用于连接阿里云并调用API接口:
```python
import urequests
import ujson
import utime
import hashlib
import hmac
def generate_signature(method, content_type, body, access_key_secret):
timestamp = str(int(utime.time() * 1000))
content_md5 = hashlib.md5(body.encode('utf-8')).hexdigest()
string_to_sign = method + '\n' + content_md5 + '\n' + content_type + '\n' + timestamp
signature = hmac.new(access_key_secret.encode('utf-8'), string_to_sign.encode('utf-8'), hashlib.sha1).digest()
signature = signature.decode('utf-8').strip()
return 'ACS ' + access_key_id + ':' + signature
access_key_id = 'your_access_key_id'
access_key_secret = 'your_access_key_secret'
url = 'https://your_domain.com/your_api'
headers = {
'Content-Type': 'application/json',
}
data = {
'param1': 'value1',
'param2': 'value2'
}
body = ujson.dumps(data)
signature = generate_signature('POST', 'application/json', body, access_key_secret)
headers['Authorization'] = signature
headers['Date'] = str(int(utime.time() * 1000))
response = urequests.post(url, headers=headers, data=body)
print(response.content.decode())
```
其中,`generate_signature`函数用于生成请求签名,需要传入请求方法、请求内容类型、请求体、以及阿里云的Access Key Secret。`access_key_id`和`access_key_secret`需要替换为你自己的阿里云Access Key信息。`url`、`headers`和`data`根据你具体的API接口进行修改。
生成一个调用腾讯API实现图像滤镜的代码
以下是一个调用腾讯云API实现图像滤镜的Python代码示例:
```python
import base64
import hashlib
import hmac
import json
import random
import time
import urllib.parse
import urllib.request
# 腾讯云API配置信息
secret_id = 'your_secret_id'
secret_key = 'your_secret_key'
endpoint = 'face.tencentcloudapi.com'
service = 'face'
version = '2018-12-03'
algorithm = 'TC3-HMAC-SHA256'
# 图片地址
image_url = 'your_image_url'
# API请求参数
params = {
'Image': image_url,
'FilterType': 1 # 滤镜类型,1表示黑白
}
# 生成TC3-HMAC-SHA256签名
def sign(secret_key, algorithm, datetime, service, version, action, params):
# 生成规范请求串
canonical_uri = '/'
canonical_querystring = ''
canonical_headers = 'content-type:application/json\nhost:{}\n'.format(endpoint)
signed_headers = 'content-type;host'
payload_hash = hashlib.sha256(json.dumps(params).encode('utf-8')).hexdigest()
canonical_request = 'POST\n{}\n{}\n{}\n{}\n{}\n{}'.format(
canonical_uri, canonical_querystring, canonical_headers, signed_headers, payload_hash, ' '.join(sorted(signed_headers.split(';')))
)
# 生成待签名字符串
date = datetime.split('T')[0]
credential_scope = '{}/{}/{}/tc3_request'.format(date, service, 'tc3_request')
hashed_request = hashlib.sha256(canonical_request.encode('utf-8')).hexdigest()
string_to_sign = '{}\n{}\n{}\n{}'.format(
algorithm, datetime, credential_scope, hashed_request
)
# 生成签名
secret_date = hmac.new(('TC3' + secret_key).encode('utf-8'), date.encode('utf-8'), hashlib.sha256).digest()
secret_service = hmac.new(secret_date, service.encode('utf-8'), hashlib.sha256).digest()
secret_signing = hmac.new(secret_service, 'tc3_request'.encode('utf-8'), hashlib.sha256).digest()
signature = hmac.new(secret_signing, string_to_sign.encode('utf-8'), hashlib.sha256).hexdigest()
# 生成Authorization头部信息
authorization = '{} Credential={}/{}, SignedHeaders={}, Signature={}'.format(
algorithm, secret_id, credential_scope, signed_headers, signature
)
return authorization
# 发送API请求
def request_api(image_url, params):
# 生成请求时间戳和随机字符串
datetime = time.strftime('%Y-%m-%dT%H:%M:%SZ', time.gmtime())
nonce = ''.join(random.choice('0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz') for i in range(32))
# 生成请求头部信息
headers = {
'Content-Type': 'application/json',
'Host': endpoint,
'X-TC-Action': 'StyleImage',
'X-TC-Version': version,
'X-TC-Timestamp': str(int(time.time())),
'X-TC-Nonce': nonce,
'Authorization': sign(secret_key, algorithm, datetime, service, version, 'StyleImage', params)
}
# 发送POST请求
req = urllib.request.Request('https://{}'.format(endpoint), data=json.dumps(params).encode('utf-8'), headers=headers, method='POST')
resp = urllib.request.urlopen(req)
result = json.loads(resp.read().decode('utf-8'))
return result
# 将返回结果中的base64编码的图片保存到本地
def save_image(base64_data, file_path):
with open(file_path, 'wb') as f:
f.write(base64.b64decode(base64_data))
# 调用API并保存结果
result = request_api(image_url, params)
save_image(result['StyledImage'], 'output.jpg')
```
需要替换代码中的 `your_secret_id` 和 `your_secret_key` 为自己的腾讯云API密钥,以及 `your_image_url` 为需要处理的图片地址。同时还可以根据需要修改滤镜类型等参数。该代码将使用黑白滤镜处理图片,并将结果保存到本地文件 `output.jpg` 中。
