The correct content-type for JSON data is <code>application/json</code>. I assume that is what you are missing.

blocks|key|908279|text|我不认为Chrome开发者工具能很好地打印XHR内容。请参阅：Viewing+HTML+response+from+Ajax+call+through+Chrome+Developer+tools?|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|908280|entityMap|0|LINK|mutability|MUTABLE|url|https://stackoverflow.com/questions/3181287/viewing-html-response-from-ajax-call-through-chrome-developer-tools^0|V|1W|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

I don't think the Chrome Developer tools pretty print XHR content. See:

Google Chrome now supports this (<code>Developer Tools &gt; Network &gt; [XHR item in list] Preview</code>). 

In addition, you can use a third party tool to format the json content. <a href="http://jsonviewer.stack.hu/" rel="noreferrer">Here</a>'s one that presents a tree view, and <a href="http://www.jsonlint.com/" rel="noreferrer">here</a>'s another that merely formats the text (and does validation).

blocks|key|908424|text|我找到了答案：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|908425|您必须这样编码您的json：{"c":21001,"m":"p"}，而不是{c:21001,m:"p"}或{'c':21001,'m':'p'}|offset|length|style|CODE|908426|因此，dict的关键字必须用双引号括起来："，然后chrome会将其预览为json而不是纯文本。|908427|entityMap^0|0|E|J|11|F|1H|J|0|L|1|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|M|8|@$D|N|E|O|F|G]|$D|P|E|Q|F|G]|$D|R|E|S|F|G]]|9|@]|A|$]]|$1|H|3|I|5|6|7|T|8|@$D|U|E|V|F|G]]|9|@]|A|$]]|$1|J|3|-4|5|6|7|W|8|@]|9|@]|A|$]]]|K|$]]

I've found the answer:

You MUST encode your json like this: <code>{"c":21001,"m":"p"}</code> but not <code>{c:21001,m:"p"}</code> or <code>{'c':21001,'m':'p'}</code>

Thus, the key of a dict must be wrapped in double quotes:<code>"</code>, then chrome will preview it as json rather than plain text.

blocks|key|1123498|text|为了让它正确地显示JSON消息，它必须具有"application/json“mime类型，并且结构正确。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1123499|您可以检查结构here|offset|length|1123500|entityMap|0|LINK|mutability|MUTABLE|url|http://jsonlint.com/^0|0|7|4|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|O|8|@]|9|@$D|P|E|Q|1|R]]|A|$]]|$1|F|3|-4|5|6|7|S|8|@]|9|@]|A|$]]]|G|$H|$5|I|J|K|A|$L|M]]]]

I cannot find an answer to this one:
My AJAX calls return JSON data. In Google Chrome Developer Tools &gt; Resources &gt; XHR when I click on the resource on the left and then on the Content tab I see the JSON string as a string and not as a tree as Firebug and Firebug Lite do.
How do I force Chrome to display it as a tree. Is there a Content-type that my PHP file must have???

Google Chrome display JSON AJAX response as tree and not as a plain text
