如何通过HTTP接口进行调用

[taoshihan1991]

在docker部署后，不能通过python调用，如何进行http接口调用呢？

[Zengyi-Qin]

you need to deploy http service by your own

[lonngxiang]

like this

api.py

from flask import Flask, Response, request
import io
from melo.api import TTS

app = Flask(__name__)


# Speed is adjustable
speed = 1.0
device = 'cuda:0' # or cuda:0



@app.before_request
def load_model():
    if not hasattr(app, 'model'):
        app.model = TTS(language='ZH', device=device)


@app.route('/audio', methods=['POST'])
def get_audio():
    bio = io.BytesIO()
    speaker_ids = app.model.hps.data.spk2id
    data = request.json
    text = data.get('text')
    print(speaker_ids, text)
    app.model.tts_to_file(text, speaker_ids['ZH'], bio, speed=speed)
    return bio.getvalue()


if __name__ == '__main__':
    app.run(host='***', port=***, debug=True)

我是在本地windows docker部署的，直接python类库没法调用，想调用docker部署好的http服务端的接口

Thanks for the tip. I tried your code. It returned the follow error.

api.py trying to write to a file and _io.BytesIO does not contain file format information. Anything else I can try here, thanks.
