如何让 Ajax.Net PageMethod 返回 JSON

发布于 2024-08-17 19:25:39 字数 916 浏览 12 评论 0 原文

我正在使用 AJAX.Net 调用 ASP.Net PageMethod，它返回 JSON 序列化 JSON 数据

{"d":"[{\"Fromaddress\":\"[email protected]\",\"Toaddress\":\"[email protected]\"},{\"Fromaddress\":\"[email protected]\",\"Toaddress\":\"[email protected]\"}]"}

响应标头将内容类型声明为

"Content-Type   application/json; charset=utf-8"

但是，数据仅作为字符串提供，并且似乎不作为 JSON 数据提供来自 JavaScript。我需要做什么才能使用 javascript 返回的 JSON 数据？

I am using an AJAX.Net to call an ASP.Net PageMethod, which returns JSON serialized JSON data

{"d":"[{\"Fromaddress\":\"[email protected]\",\"Toaddress\":\"[email protected]\"},{\"Fromaddress\":\"[email protected]\",\"Toaddress\":\"[email protected]\"}]"}

The Response Header states the content type as

"Content-Type   application/json; charset=utf-8"

However, the data is just available as a string, and does not seem to be available as JSON data from javascript. What do I need to do to work with the returned data as JSON from javascript?

var myData = eval('(' + text + ')');

尽管这可能存在安全风险。相反，您可能想使用 JSON 解析器，例如这个可用的形式 https://github.com/douglascrockford/JSON-js/blob/master/json2.js

然后你会得到如下符号：

var myData = JSON.parse(text);

参见 http://www.json.org/js.html 有关此特定解析器的更多信息...我相信还有其他解析器可供选择，并且它们的工作方式非常相似。

var myData = eval('(' + text + ')');

Although this can be a security risk. Instead you might want to use a JSON parser, such as this one available form https://github.com/douglascrockford/JSON-js/blob/master/json2.js

Then you get notation like:

var myData = JSON.parse(text);

See http://www.json.org/js.html for more info on this particular parser... I believe there are others to choose from, and that they work very similarly.
