POST 请求没问题，GET 方式请求出错：
解决方法
json方法有一个重构：
<span class="kwd">public</span><span class="pln"> </span><span class="typ">JsonResult</span><span class="pln"> </span><span class="typ">GetPersonInfo</span><span class="pun">()</span><span class="pln"> </span><span class="pun">{</span><span class="pln"></span><span class="kwd">var</span><span class="pln"> person </span><span class="pun">=</span><span class="pln"> </span><span class="kwd">new</span><span class="pln"> </span><span class="pun">{</span><span class="pln"></span><span class="typ">Name</span><span class="pln"> </span><span class="pun">=</span><span class="pln"> </span><span class="str">"张三"</span><span class="pun">,</span><span class="pln"></span><span class="typ">Age</span><span class="pln"> </span><span class="pun">=</span><span class="pln"> </span><span class="lit">22</span><span class="pun">,</span><span class="pln"></span><span class="typ">Sex</span><span class="pln"> </span><span class="pun">=</span><span class="pln"> </span><span class="str">"男"</span><span class="pln"></span><span class="pun">};</span><span class="pln"></span><span class="kwd">return</span><span class="pln"> </span><span class="typ">Json</span><span class="pun">(</span><span class="pln">person</span><span class="pun">,</span><span class="typ">JsonRequestBehavior</span><span class="pun">.</span><span class="typ">AllowGet</span><span class="pun">);</span><span class="pln"></span><span class="pun">}</span> |
这样一来我们在前端就可以使用Get方式请求了：
<span class="pln">$</span><span class="pun">.</span><span class="pln">getJSON</span><span class="pun">(</span><span class="str">"/FriendLink/GetPersonInfo"</span><span class="pun">,</span><span class="pln"> </span><span class="kwd">null</span><span class="pun">,</span><span class="pln"> </span><span class="kwd">function</span><span class="pun">(</span><span class="pln">data</span><span class="pun">)</span><span class="pln"> </span><span class="pun">{</span><span class="pln">$</span><span class="pun">(</span><span class="str">"#friendContent"</span><span class="pun">).</span><span class="pln">html</span><span class="pun">(</span><span class="pln">data</span><span class="pun">.</span><span class="typ">Name</span><span class="pun">);</span><span class="pln"></span><span class="pun">})</span> |
