Question

我必须在python中发送post请求以获取以下数据

curl -X POST -u "{username}":"{password}"
--header "Content-Type: audio/flac"
--data-binary "@audio-file1.flac"
"https://stream.watsonplatform.net/speech-to-text/api/v1/recognize?timestamps=true&word_alternatives_threshold=0.9&keywords=%22colorado%22%2C%22tornado%22%2C%22tornadoes%22&keywords_threshold=0.5"

Answer 1

您可以先阅读post requests的文档。

这将向您的curl命令发送类似的请求：

import requests

url = 'https://stream.watsonplatform.net/.......'
auth = ('{username}', '{password}')
headers = {'Content-type': 'audio/flac'}

with open('audio-file1.flac', 'rb') as f:
    r = requests.post(url, auth=auth, headers=headers, data=f)

部分标题会有所不同，例如User-Agent，但请求是相同的。

您可以改为使用字典并将其传递给requests.post()，而不是在查询字符串中手动放置和转义查询参数：

url = 'https://stream.watsonplatform.net/speech-to-text/api/v1/recognize'
params = {
    'keywords': '"colorado","tornado","tornadoes"',
    'keywords_threshold': '0.5',
    'timestamps': 'true',
    'word_alternatives_threshold': '0.9'
}

with open('audio-file1.flac', 'rb') as f:
    r = request.post(url, params=params, auth=auth, headers=headers, data=f)
