在下面的脚本，我张贴JSON格式到服务器的数据，但响应发送回纯文本。

In the following script, I post data in JSON format to the server, but the response is sent back in plain-text.

    var regCredentials = {

        "username": creds.username,
        "password": creds.password,
        "fname": creds.fname,
        "lname": creds.lname

    };

    request = $.ajax({

        url: "internet.com/register",
        type: "POST",
        crossDomain: true,
        data: regCredentials,
        dataType: "json";

        request.always(function (data) {

                console.log("Response: " + data);
                postResponse(data);

        };

    });

由于该函数需要JSON回来，追加到返回的数据。它很可能已经分析过，这不出于某种原因抛出异常。

Because the function expects JSON back, a " is appended to the returned data. It's probably parsed too, which doesn't throw an error for some reason.

我怎么能写一个jQuery AJAX后接受纯文本格式的反应呢？

编辑：

我的困惑我认识，是我觉得数据确定传出和传入期望的格式，而不是仅仅传入。嗯，这没有太大的意义不是吗？感谢您的回答！

My confusion I realize, is that I thought data determined the outgoing and incoming expected format rather than just incoming. Well that doesn't make much sense does it? Thanks for the answer!

推荐答案

在的dataType 参数是用来设置预期的反应类型。在你的情况下，将其设置为文本。这不影响其以任何方式发送的信息。当你发送一个POST请求，该信息将被放置在请求标题。如果这是一个GET，它会被序列化到一个字符串，并追加到查询字符串的URL。

The dataType parameter is used to set the expected response type. In your case, set it to text. This does not affect the information which is sent in any way. As you are sending a POST request, the information will be placed in the requests' header. If it was a GET, it would be serialised to a string and appended to the URL in the querystring.

您身边的处理函数的语法是有点过了。试试这个：

Your syntax around the handler function was a little off too. Try this:

var regCredentials = {
    "username": creds.username,
    "password": creds.password,
    "fname": creds.fname,
    "lname": creds.lname
};

request = $.ajax({
    url: "internet.com/register",
    type: "POST",
    crossDomain: true,
    data: regCredentials,
    dataType: "text",
    success: function (data) {
        console.log("Response: " + data);
        postResponse(data);
    }
});
