Hello everyone, I am not warm Bu fire, School of Computer Science is a big data professional junior, nickname comes from the phrase -
不温不火, which was intended希望自己性情温和. As a novice in the Internet industry, a blogger writes a blog to record his own learning process on the one hand, and on the other hand to summarize the mistakes he has made, hoping to help many young people who are just like him in their infancy. However, due to the limited level, there will inevitably be some mistakes in the blog. If there are any omissions, please let me know! For the time being, it will only be updated on the csdn platform, the blog homepage: https://buwenbuhuo.blog.csdn.net/ .

Ok! Please forgive the blogger for not being punctual recently. As for the reason~ Due to the crazy overdraft some time ago, now the blogger is really pale by comparison. There is a sentence that perfectly verifies the current situation of bloggers: there is really no drop -. -Here, the blogger just wants to say: Young people don’t know how expensive they are, but they are always crying when they are always looking. Ah sorry to drive 0.0
Although the energy is lacking, the update speed may be slower than before. But the blogger hereby guarantees that it is impossible to break, and it is impossible to break it in this life. During this period of time, the update Scrapy_Spiderpart may be suspended first Spider_Web, and some small demos updated first are for everyone. As for why Scrapy_Spiderthis part is suspended ? Don't ask, ask is precipitation-. -
Hahaha, well, no more nonsense. The following feature film begins...
Before starting to make a simple translation tool, we need to clarify which translation interface we use.
The blogger chose the interface of Baidu Translation this time.
The following is the URL translated by Baidu: https://fanyi.baidu.com/
However, by looking at the web page structure, we found that this URL is not what we need, so we need to find an interface.
1. Get the request interface of Baidu translation
- 1. Open the browser F12 to open the source code of Baidu translation webpage
If the above picture occurs, we can lose a few more times https://fanyi.baidu.com/sug. As shown below:
- 2. Find the parameter from the request whose method is POST: kw:hi (hi is the content of the input translation)
From the above figure, we can easily see that it datais a list, which is stored as key-value pairs, and there are several words and meanings, and only the first one is what we need, then we can go to the first The value of a key-value pair can be:["data"][0]["v"])
2. Writing ideas
Now that the interface has been found, the next step is to analyze how to write code. Writing code generally requires the following steps:
- 1. First, we need to set a request header to simulate it as a browser, which is the most basic countermeasure
headers = {
"user-agent": "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/55.0.2883.87 Safari/537.36",
}
- 2. Send a post request, get json, and convert it into a dictionary
#发送post请求
response = requests.post(url=url,params=params,headers=headers)
#获取返回内容，这里是json，获取json数据转字典
content = response.json()
#获取数据
print(content)
- 3. Get word meaning
print(content["data"][0]["v"])
3. Original program and package modification program
- 1. Original program
#!/usr/bin/env python
# encoding: utf-8
