read excel data from stream
Sure, you can use the pandas library in Python to read Excel data from a stream. Here's an example code snippet:
```
import pandas as pd
import io
# Assume input_data is a stream containing Excel data
input_data = b"..."
# Load the data into a pandas dataframe
df = pd.read_excel(io.BytesIO(input_data), sheet_name="Sheet1")
# Do whatever you want with the dataframe!
print(df.head())
```
This will read the Excel data from the stream `input_data`, and load it into a pandas dataframe. You can then use the dataframe to do whatever you want with the data.
vue get data from http
To get data from an HTTP endpoint in Vue.js, you can use the built-in `axios` library. Here's an example:
1. Install axios by running `npm install axios` in your project directory.
2. Import axios into your Vue component:
```javascript
import axios from 'axios';
```
3. In your component's `mounted()` function, make a GET request to the HTTP endpoint:
```javascript
mounted() {
axios.get('https://example.com/api/data')
.then(response => {
// handle successful response
console.log(response.data);
})
.catch(error => {
// handle error
console.log(error);
});
}
```
4. In the `then` block, you can access the response data using `response.data`. You can then update your component's data with this information.
Note that this example assumes that your HTTP endpoint returns JSON data. If your endpoint returns a different format, you'll need to adjust your code accordingly.
