如何做好网站内链爱站网注册人查询

一、接口请求

http 请求包含：请求行、请求头、请求体。【关于详情】

http协议报文

1.请求报文　(请求行/请求头/请求数据/空行)	请求行： 　　请求方法字段、URL字段和HTTP协议版本 　　例如：GET/index.htmlHTTP/1.1 　　　　get方法将数据拼接在url后面，传递参数受限 　　请求方法： 　　　　GET、POST、HEAD、PUT、DELETE、OPTIONS、TRACE、CONNECT 请求头(key－value形式)： 　　User-Agent：产生请求的浏览器类型。 　　Accept：客户端可识别的内容类型列表。 　　Host：主机地址 请求数据： 　　post方法中，会把数据以keyvalue形式发送请求 空行： 　　发送回车符和换行符，通知服务器以下不再有请求头
2.响应报文　(状态行、消息报头、响应正文)	状态行 消息报头 响应正文

request

import requestsr = requests.get('https://api.github.com/events')                      # 获取网页信息
r = requests.post('http://httpbin.org/post', data = {'key':'value'})   # 发送信息请求r = requests.put('http://httpbin.org/put', data = {'key':'value'})
r = requests.delete('http://httpbin.org/delete')
r = requests.head('http://httpbin.org/get')
r = requests.options('http://httpbin.org/get')payload = {'key1': 'value1', 'key2': 'value2'}
r = requests.get("http://httpbin.org/get", params=payload)print(r.url)       # 有返回，则URL已被正确编码
print(r.text)      # 推测的文本编码
print(r.content)   # 找到 （HTTP 和 XML自身可以指定编码格式）文本编码
print(r.encoding)  # 常用于中文乱码解决。用于修改编码方式（使用 codecs 模块进行注册）

Requests 也可以使用定制的编码：
创建了自己的编码，如r.encoding = ‘ISO-8859-1’ 并使用 codecs 模块进行注册，你就可以轻松地使用这个解码器名称作为 r.encoding 的值， 然后由 Requests 来为你处理编码。
关于【响应中文乱码问题请点击】。

二、二进制请求与响应

GET 请求

以请求返回的二进制数据保存图片，保存文件。

import requests
from PIL import Image
from io import BytesIOurl = 'https://api.github.com/some/endpoint'
headers = {'user-agent': 'my-app/0.0.1'}
r = requests.get(url, headers=headers)i = Image.open(BytesIO(r.content))with open(filename, 'wb') as fd:for chunk in r.iter_content(chunk_size):fd.write(chunk)

POST 请求

import requestspayload = {'key1': 'value1', 'key2': 'value2'}r = requests.post("http://httpbin.org/post", data=payload)  # 简单地传递一个字典给 data 参数
r = requests.post(url, data=json.dumps(payload))            # 传递str 而不是dict，数据会被直接发布出去。
print(r.text)
print(r.content)
print(r.url)
print(r.status_code)

多部分编码(Multipart-Encoded)的文件

url = 'http://httpbin.org/post'
files = {'file': open('report.xls', 'rb')}# 显式地设置文件名，文件类型和请求头
files = {'file': ('report.xls', open('report.xls', 'rb'), 'application/vnd.ms-excel', {'Expires': '0'})}# 发送作为文件来接收的字符串
files = {'file': ('report.csv', 'some,data,to,send\nanother,row,to,send\n')}>>> r = requests.post(url, files=files)

建议你用二进制模式(binary mode)打开文件。这是因为 Requests 可能会试图为你提供 Content-Length header，在它这样做的时候，这个值会被设为文件的字节数（bytes）。如果用文本模式(text mode)打开文件，就可能会发生错误。
最好先用二进制的形式打开文件，将其编码成base64来进行传输：
a = open("pdf_reference.pdf", "rb").read().encode("base64")

带参数，带请求头
小示例：

import requests
import jsonurl = 'http://official-account/app/messages/group'
body = {"type": "text", "content": "text", "tag_id": "20717"}
headers = {'content-type': "application/json", 'Authorization': 'APP appid = 4abf1a,token = 9480295ab2e2eddb8'}response = requests.post(url, data = json.dumps(body), headers = headers)

三、关于图片的请求

图片和二进制格式互转

# 以 二进制方式 进行图片读取
with open("img.jpg","rb") as f:img_bin = f.read() # 以二进制方式读取的图片内容# 将 图片的二进制内容 转成 真实图片
with open("img.jpg","wb") as f:f.write(img_bin) # img_bin里面保存着二进制流的图片内容

图片转成字节数组 image2bytearray
我打印了这两者输出，有些微差别，可以都试一下

import io
from PIL import Image#================ 方法一 ===================
img = Image.open(r"C:\Users\xxx\Desktop\111.png", mode='r')imgByteArr = io.BytesIO()
img.save(imgByteArr, format='png')imgByteArr = imgByteArr.getvalue()
print('imgByteArr:',imgByteArr)#================ 方法二 ==================
data = open(r"C:\Users\xxx\Desktop\111.png", 'rb').read()
print('bytearray:',bytearray(data))

安装依赖：pip3 install Pillow

from io import BytesIO
from PIL import Image
import requestsres = requests.get('http://p1.pstatp.com/list/300x196/pgc-image/152923179745640a81b1fdc.webp', stream=True)  # 获取字节流最好加stream这个参数
byte_stream = BytesIO(res.content)   # 把请求到的数据转换为Bytes字节流(这样解释不知道对不对，可以参照[廖雪峰](https://www.liaoxuefeng.com/wiki/0014316089557264a6b348958f449949df42a6d3a2e542c000/001431918785710e86a1a120ce04925bae155012c7fc71e000)的教程看一下)roiImg = Image.open(byte_stream)      # Image打开Byte字节流数据imgByteArr = io.BytesIO()             # 创建一个空的Bytes对象
roiImg.save(imgByteArr, format='PNG') # PNG就是图片格式，我试过换成JPG/jpg都不行
imgByteArr = imgByteArr.getvalue()    # 这个就是保存的图片字节流# 写入本地
with open("./abc.png", "wb") as f:f.write(imgByteArr)#================ 方法三 ==================
img = Image.open(BytesIO(byte_stream))
img.save(save_name + img.format, quality=95)img = Image.open(BytesIO(byte_stream))
img.save(save_name + img.format, quality=95)img = Image.frombytes("RGB", (18,18), img) # 图片格式，图片大小，图片数据流
img.save("111.png")

四、Python调用WebService接口

关于WebService查看【wiki网址】。
Python的WebService开发库是soaplib。 【关于开发示例】
Suds: 是一个轻量级的SOAP客户端，suds-jurko是suds的一个分支版本。

suds：https://pypi.org/project/suds/ 最近维护时间: Sep 15, 2010
suds-jurko 0.4.1.jurko.2：https://pypi.org/project/suds-jurko/0.4.1.jurko.2/最近维护时间:Dec 25, 2011
安装 pip install suds
安装：pip install suds-jurko==0.4.1.jurko.2

免费的webserver网址：http://www.webxml.com.cn/zh_cn/web_services.aspx
测试工具：
接口使用cxf编写：SoapUI 5.2.1：下载地址，测试查看1。测试查看2。
也可以用：Webservice测试工具 Storm测试。

#encoding:utf-8
import json
from suds.client import Client# import logging
# logging.basicConfig(level=logging.INFO)
# logging.getLogger('suds.client').setLevel(logging.DEBUG)# username = 'api_user'
# password = 'api_pwd'url="http://192.168.18.74/api/Calculator/soap11/description"
headers = {'Content-Type': 'application/soap+xml; charset="UTF-8"'}client = Client(url,headers=headers,faults=False,timeout=15)def call_api_test(num1,num2):try:#--WSDL请求Header----------------------------------------------# auth = client.factory.create('AuthenticationInfo')# auth.userName = username# auth.password = password# client.set_options(soapheaders=auth)#--WSDL请求Body----------------------------------------------result = client.service.add(a=num1,b=num2)if result[0] == 200:return (True, result[1])else:return (False, result[1])except Exception as e:return (False, e)if __name__ == '__main__': #get_softwarea= call_api_test(2,3)print (json.loads(a[1]))

python3测试一个小案例

from suds.client import Clienturl = "http://www.webxml.com.cn/webservices/qqOnlineWebService.asmx?wsdl"client = Client(url)    #创建Webservice Client对象
print(client)           #打印出Client对象所有的方法result = client.service.qqCheckOnline("xxxxxxxx")  #使用client.service.qqCheckOnline方法
print("结果为："+result)

suds-community 0.8.4：https://pypi.org/project/suds-community/ 最近维护时间: Dec 22, 2019
安装：pip install suds-community

from suds.client import Client# 连接到webservice服务，获取查询天气服务方法
client = Client('http://ws.webxml.com.cn/WebServices/WeatherWS.asmx?wsdl')
print(client)

报错：suds.TypeNotFound: Type not found:

# 解决错误
from suds.client import Client
from suds.xsd.doctor import ImportDoctor, Import# 导入正确的命名空间。
imp = Import('http://www.w3.org/2001/XMLSchema', location='http://www.w3.org/2001/XMLSchema.xsd')
imp.filter.add('http://WebXml.com.cn/')
doctor = ImportDoctor(imp)
client = Client('http://ws.webxml.com.cn/WebServices/WeatherWS.asmx?wsdl', doctor=doctor)
print(client)

五、Python HmacSHA1 加密与签名

#!/usr/bin/env python3
# -*- coding: utf-8 -*-import json
import math
import os
import io
import requests

import datetime
import hashlib
