Django的/ AJAX：无法获取阿贾克斯后的数据在views.py [英] django/ajax: Unable to get Ajax post data in the views.py

问题描述

我有一个问题，从Django的后端越来越阿贾克斯后的数据，我不知道该如何传递值，请大家帮忙。

I had a problem getting ajax post data from django backend, I don't know how to pass the value, please help.

在HTML我只是这样的：

In html I have simply this:

<form id="get_vulns_from_family">
    <label for="family_content">Enter a family name to display the NVTs</label>
    <input id="family_content" />
    <input type="submit" value="search" />
</form>

在JavaScript的我写的：

In javascript I wrote this:

$(function() {
    $("#get_vulns_from_family").submit(function(event) {
        var family_text = $("#family_content").val();
        var family_data = {"family": family_text};
        $.ajax({
            url: "/template_conf/get_vulns_from_family",
            type: "POST",
            data: family_data,
            success: function(response) {
                console.log(response);
            },
            error: function(response) {
                console.log("failed!");
            }
        });
        // prevent default posting of form
        event.preventDefault();
    });
});

在对应的URL Django的方法 / template_conf / get_vulns_from_family ，我想这样的：

In Django method corresponding to url /template_conf/get_vulns_from_family, I tried this:

def get_vuln_from_family(request):
    family = request.POST['family']
    # some other operations to get value for variable "json_data"
    return HttpResponse(simplejson.dumps(json_data))

不过在Django说： MultiValueDictKeyError：的QueryDict钥匙'家庭'未与＆lt发现：{}＆GT;，这意味着POST字典是空的。 我使用了错误的方式来获得数据后？如果是的话我该怎么办？谢谢你。

But django said: MultiValueDictKeyError: "Key 'family' not found in <QueryDict: {}>", which means the POST dictionary is empty. Am I using the wrong way to get post data? If so what should I do? Thanks.

推荐答案

您的网址/ template_conf / get_vulns_from_family缺少最后的斜线。 Django会通常重定向为/ template_conf / get_vulns_from_family /，下探 POST 数据

your url "/template_conf/get_vulns_from_family" is missing a trailing slash. django will typically redirect this to "/template_conf/get_vulns_from_family/", dropping the POST data
