Question

在谷歌应用发动机(python sdk)中,我会利用 j,发出Ajax请求,储存一个问题的答案。

向服务器发送这一数据的最佳方式是什么? 目前,我有:

function storeItem(question_id) {
        var answerInputControl = ".input_answer_"+question_id;
        var answer_text = $(answerInputControl).text();
        $.ajax({
            type: "POST",
            url: "store_answer.html",
            data: "question="+question_id,
            success: function(responseText){
                alert("Retrieved: " + responseText);
            }
        });
    }

这是一个问题,通过电梯向服务器提供。但是,在服务器方面,我无法查阅我想要储存的答案控制的内容。如果没有Ajax,我就能够以下列方式开展这一行动:

class StoreAnswers(webapp.RequestHandler):
def post(self):
    question_id = self.request.get("question_id")
    answer_text = self.request.get("input_answer" + question_id)

但在通过Ajax发出这一呼吁时,我的<代码>answer_text是空的。

Do I need to send the contents of this control as part of the data with the Ajax request?
Do I add the control itself to the query string? Its contents? Does it matter that the content might be a few hundred characters long? Is this the most-recommended practice?
If sending it as a query string, what s the best way to escape the content so that a malicious user doesn t harm the system?

www.un.org/Depts/DGACM/index_french.htm 电话必须包括你希望发送的所有数据——寄出数百个特性绝对不是问题,而且无疑是所建议的做法。

http://www.un.org。使用<条码>GET,代替<条码>POST-<>>>。 (我怀疑是你所称的“ que”的意思)只能购买你的各种麻烦,并且违反了的语义。 (应限于“单纯的”查询,而不附带影响。)

Answer 2

你的数据格式不正确:

data: {
    question_id: question_id,
    input_answer: $(answerInputControl).text()
}
