I'm trying to get this json request into df, my code is like this
gateio = requests.get("https://data.gateapi.io/api2/1/tickers")
e = gateio.json()
gateio = json_normalize(e)
print(gateio)
I get the data not correctly.

Use:
gateio = pd.json_normalize(e)
gateio.columns = gateio.columns.str.split('.', expand=True)
df = gateio.rename_axis(('symbol', None), axis=1).stack(0).droplevel(0).reset_index()

Another idea is create DataFrame by constructor and pivoting:
gateio = requests.get("https://data.gateapi.io/api2/1/tickers")
e = gateio.json()
df = pd.DataFrame([(k,k1, v1) for k, v in e.items() for k1, v1 in v.items()]).pivot(0,1,2)
print(df)
