要实现边循环爬取json边写入Excel,可以按照以下步骤进行操作:
1. 导入所需的库:
```python
import requests
import json
import openpyxl
```
2. 循环请求API并获取JSON数据:
```python
url = 'https://example.com/api/data'
response = requests.get(url)
data = json.loads(response.text)
```
3. 创建一个Excel文件并设置活动工作表:
```python
workbook = openpyxl.Workbook()
worksheet = workbook.active
```
4. 循环遍历JSON数据并将其写入Excel行:
```python
for row in data:
worksheet.append(row.values())
```
5. 保存Excel文件:
```python
workbook.save('data.xlsx')
```
6. 将以上步骤放入一个循环中,以便可以持续爬取JSON数据并将其写入Excel中:
```python
while True:
response = requests.get(url)
data = json.loads(response.text)
workbook = openpyxl.Workbook()
worksheet = workbook.active
for row in data:
worksheet.append(row.values())
workbook.save('data.xlsx')
```
这样就可以实现边循环爬取JSON边写入Excel的操作了。
