Question

所以我想使用flask将数组发送到python脚本。

这是我相关的javascript：

var blacklist = [1];
function getSents() {
 $.ajax({
    type: "POST",
    url: "script.py",
    data: {'blacklist':blacklist},
    dataType: 'json',
    success: function(response) {
        // do something
        },
    error: function (xhr, status, error) {
        console.log(error);
        }
});
}

在烧瓶中，我尝试了发现的每个请求属性。打印时，它始终会提供一个空字节字符串。

如果我使用

json.loads(request.data)

由于request.data为空，因此会引发错误。

相关的python代码：

from flask import Flask
from flask import render_template
from flask import request
from flask import jsonify
application = Flask(__name__)

@application.route('/', methods=['GET', 'POST'])
def something():
    blacklist = request.get_data()
    # do something

if __name__ == '__main__':
    application.run(debug=True)

Answer 1

尝试将contentType设置为'application / json'并对数据属性进行字符串化。然后在烧瓶中检查request.json

var blacklist = [1];
function getSents() {
 $.ajax({
    type: "POST",
    url: "script.py",
    data: JSON.stringify({'blacklist':blacklist}),
    contentType: "application/json",
    dataType: 'json',
    success: function(response) {
        // do something
        },
    error: function (xhr, status, error) {
        console.log(error);
        }
});
}

如果您正在寻找一个以此为起点的起点，那么应该可以

在app.py下

from flask import Flask
from flask import render_template
from flask import request
from flask import jsonify
application = Flask(__name__, static_url_path='/static')

@application.route('/', methods=['GET', 'POST'])
def something():
    if request.method == 'GET':
        return application.send_static_file('index.html')
    blacklist = request.json
    print(blacklist)
    return jsonify(blacklist)

if __name__ == '__main__':
    application.run(debug=True)

然后在/static/index.html

下

<!DOCTYPE html>
<html>
    <head>
        <title>Test</title>
        <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

    </head>
    <body>
       <script>
        var blacklist = [1];
        function getSents() {
         $.ajax({
            type: "POST",
            url: "script.py",
            data: JSON.stringify({'blacklist':blacklist}),
            contentType: "application/json",
            dataType: 'json',
            success: function(response) {
                // do something
                console.log(response)
                },
            error: function (xhr, status, error) {
                console.log(error);
                }
        });
        }
        getSents();
        </script>
    </body>
</html>

request.get_data（），request.form等始终为空
