如何在python中进行api调用？

Question

我在我的机器上运行了 tika 服务器并使用终端调用 api，它工作正常。我能够从图像和 pdf 中提取文本。但是，我想在我的 python 应用程序中实现 api 调用。

curl -T price.xls http://localhost:9998/tika --header "Accept: text/plain"

以上是我必须进行的 api 调用。我可以在我的终端中运行它并且工作正常，但是如何在 python 应用程序中实现。我已经安装并尝试了请求。

API_URL = 'http://localhost:9998/tika'
APP_ROOT = os.path.dirname(os.path.abspath(__file__))
tika_client = TikaApp(file_jar=join(APP_ROOT,'../tika-app-1.19.jar'))
data = {
    "url": join(APP_ROOT,'../static/image/a.pdf')
}
response = requests.put(API_URL, data)
print(response.content)

任何帮助将不胜感激。谢谢:)

错误输出

Answer 1

您需要定义数据（有效负载），标头。

url = 'http://localhost:9998/tika/......'
headers = {"Accept: text/plain"}
response = requests.put(url,data = data, headers=headers)
