Javascript analyze（）缺少一个位置参数：'；请求'；

我正在尝试发送一个图像URL

var photoData = $("#photo").attr("src");

// console.log(photoURL);
console.log(photoData);

var data = photoData;
$.post("/analyze", data)
      .done((prediction) => {
           console.log('success')
      })

使用flaskpython创建此路由

@app.route('/analyze', methods=['POST'])
async def analyze(request):
    predictionRaw = learn.predict(open_image(get_image_files(request)[0]))
    prediction = str(predictionRaw)
    return prediction

learn.predict（）

使用快速人工智能库。对于Python代码，我实际上遵循了这一点

但出于某种原因，它总是给我这个错误

analyze（）缺少一个必需的位置参数：“request”

为什么会这样？我做错了什么？我确信我已经正确地使用JS Ajax发送了请求参数

您没有在url中传递

请求

。它自动进入请求范围。尝试：

from flask import request

@app.route('/analyze', methods=['POST'])
def analyze():

    print(request.get_data()) # to see what you're sending

    predictionRaw = learn.predict(open_image(get_image_files(request.data)))
    prediction = str(predictionRaw)
    return prediction

始终将完整的错误消息（从单词“Traceback”开始）作为文本（而不是屏幕截图）进行讨论（不是评论）。还有其他有用的信息。@furas我刚刚用回溯编辑了我的问题。我想它有用吧？输出终端上不再有回溯错误，但在浏览器控制台上我得到了

POSThttp://url/analyze 500（内部服务器错误）

错误。
