Python 如何解决'；请求此服务器无法理解'；错误？

我用Flask构建了一个API，在用postman测试它时不断出现错误

我只是在添加线程以便在将数据返回给postman后可以继续运行scraper时才开始出现此错误，现在我不确定如何克服此问题

我的代码如下所示：

from threading import Thread
from flask import Flask

application = Flask(__name__)

class Compute(Thread):
    def __init__(self, request):
        print("init")
        Thread.__init__(self)
        self.request = request

    def run(self):
        print("RUN")
        command = './webscraper.py -us "{user}" -p "{password}" -url "{url}"'.format(**self.request.json)
        output = subprocess.call(['bash','-c', command])
        print("done")

@application.route('/scraper/run', methods=['POST'])
def init_scrape():
    thread_a = Compute(request.__copy__())
    thread_a.start()
    return jsonify({'Scraping this site: ': request.json["url"]}), 201

if __name__ == '__main__':
    application.run(host="0.0.0.0", port="8080")

我的帖子数据只是一个站点url和登录到它的详细信息，看起来像这样

data = {

{
    "user":"username",
    "password":"password",
    "url":"www.mysite.com/"

}

如果我与邮递员一起向

localhost:8080/scraper/run

发出POST请求，我会收到以下错误：

我正在发送我在没有线程的情况下工作时使用的同一个POST请求检查日志，在我们的函数中添加打印内容，并让我们知道发生了什么事情。如果包含您要求邮递员发送的请求的详细信息，我也会很有帮助。更新了我的帖子，并提供了两个建议检查日志，在我们的功能中添加打印内容，让我们知道什么是Happenst，包括您要求邮递员发送的请求的详细信息也会有所帮助。更新了我的帖子，并提供了这两个建议
