urllib.urlencode(param)

`urllib.urlencode(param)` is a function in Python's `urllib` module that takes a dictionary or sequence of two-element tuples and returns a string in the format of a query string. It is often used to encode the parameters of a GET request for a web API.
For example, if you have a dictionary `params` with the values `{'name': 'John', 'age': 30}`, calling `urllib.urlencode(params)` would return the string `"name=John&age=30"`, which can then be appended to the end of a URL to make a GET request with those parameters.

import urllib.parse
`import urllib.parse` 是Python中用于解析URL的模块。它提供了一些函数和类,用于处理URL字符串的各个部分,例如协议、主机、路径、查询参数等。
该模块中最常用的函数是`urllib.parse.urlparse()`,它可以将一个URL字符串解析成一个包含各个部分的元组。例如:
```python
from urllib.parse import urlparse
url = "https://www.example.com/path?param1=value1¶m2=value2"
parsed_url = urlparse(url)
print(parsed_url.scheme) # 输出:https
print(parsed_url.netloc) # 输出:www.example.com
print(parsed_url.path) # 输出:/path
print(parsed_url.query) # 输出:param1=value1¶m2=value2
```
除了`urlparse()`函数外,`urllib.parse`模块还提供了其他一些函数,例如:
- `urlunparse()`:将一个包含各个部分的元组拼接成一个完整的URL字符串。
- `urlencode()`:将字典或元组形式的查询参数编码成URL编码格式。
- `quote()`和`quote_plus()`:对URL中的特殊字符进行编码。
- `unquote()`和`unquote_plus()`:对URL中的特殊字符进行解码。
def get_result(self): uploadresp = self.upload() orderId = uploadresp['content']['orderId'] param_dict = {} param_dict['appId'] = self.appid param_dict['signa'] = self.signa param_dict['ts'] = self.ts param_dict['orderId'] = orderId param_dict['resultType'] = "transfer,predict" print("") print("查询部分:") # print("get result参数:", param_dict) status = 3 # 建议使用回调的方式查询结果,查询接口有请求频率限制 while status == 3: response = requests.post(url=lfasr_host + api_get_result + "?" + urllib.parse.urlencode(param_dict), headers={"Content-type": "application/json"}) # print(response.text) # print("get_result_url:",response.request.url) result = json.loads(response.text) # print(result) order_result_str = result['content']['orderResult'] print(order_result_str)帮我每行加上注释
当然,我可以帮你给每行代码加上注释。下面是带注释的代码:
```python
def get_result(self):
# 上传文件并获取订单号
uploadresp = self.upload()
orderId = uploadresp['content']['orderId']
param_dict = {}
param_dict['appId'] = self.appid
param_dict['signa'] = self.signa
param_dict['ts'] = self.ts
param_dict['orderId'] = orderId
param_dict['resultType'] = "transfer,predict"
print("")
print("查询部分:")
# 建议使用回调的方式查询结果,查询接口有请求频率限制
status = 3
while status == 3:
# 发送查询结果的请求
response = requests.post(url=lfasr_host + api_get_result + "?" + urllib.parse.urlencode(param_dict),
headers={"Content-type": "application/json"})
result = json.loads(response.text)
order_result_str = result['content']['orderResult']
print(order_result_str)
```
