A straightforward solution would be to cast self.request.get("tags") in a list() however this doesn't work with me when I send a Javascript array, but maybe it would work for your case

一个简单的解决方案是在列表中投射self.request.get(“tags”)(但是当我发送一个Javascript数组时,这对我不起作用,但也许它适用于你的情况

You could serialize it into a JSON string, and this string will be treated as the post data.

您可以将其序列化为JSON字符串,并将此字符串视为发布数据。

$.ajax({
    type: "POST",
    url: "/add",
    contentType: "application/json",
    data: JSON.stringify({tags:['first tag','second tag','third tag']}),

Parses the data for example (in Java):

例如,解析数据(在Java中):

    try {
        reader = request.getReader();
    } catch (final IllegalStateException illegalStateException) {
        reader = new BufferedReader(new InputStreamReader(
                request.getInputStream()));
    }

    String line = reader.readLine();
    while (null != line) {
        sb.append(line);
        line = reader.readLine();
    }
    reader.close();

    String tmp = sb.toString();
    if (Strings.isEmptyOrNull(tmp)) {
        tmp = "{}";
    }

    return new JSONObject(tmp);
