在视图层 views.py
import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
from io import BytesIO
import base64
def get_picture(request):
plt.plot(randn(50).cumsum(), 'k--')
buffer = BytesIO()
plt.savefig(buffer)
plot_data = buffer.getvalue()
imb = base64.b64encode(plot_data) # 对plot_data进行编码
ims = imb.decode()
imd = "data:image/png;base64," + ims
context = {
'img': imd,
}
return render(request,'test.html',context)
