英文:
Problem in opening link via python webbrowser
问题
当我通过Postman发送GET请求时，有一个选项来发送并下载文件（一个HTML文件），该文件可以在浏览器中打开并执行。我希望通过以下Python代码以相同的方式执行：
from requests import get as GET
import webbrowser
tokenUrl = '...'
tokenParams = {}
r = GET(tokenUrl, params=tokenParams)
print(r.text)
webbrowser.open(r.text)
然而，这会在浏览器中显示一个错误，显示"文件未找到"错误。完整的错误消息如下：

When I send the GET request via postman there is an option to send and download and the download file(an html file) is executable which opens In a browser.
I wish to do the same via python via following code.
from requests import get as GET
import webbrowser
tokenUrl = '...'
tokenParams = {}
r = GET(tokenUrl,params = tokenParams)
print(r.text)
webbrowser.open(r.text)
However this displays an error in browser saying filenotfound error.

我发现[如何处理响应][1]的请求文档对解决错误很有帮助。
现在的代码看起来如下：
```python
r = GET(tokenUrl, params=tokenParams)
with open('response.html', 'wb') as fd:
for chunk in r.iter_content(chunk_size=128):
fd.write(chunk)
webbrowser.open('response.html')
英文:
I found the requests' documentation on how to handle response helpful in resolving the error.
Code now looks as
r = GET(tokenUrl,params = tokenParams)
with open('response.html', 'wb') as fd:
for chunk in r.iter_content(chunk_size=128):
fd.write(chunk)
webbrowser.open('response.html')
