查看Json輸出的*最方便*的方法 (轉(zhuǎn))
更新時(shí)間：2009年11月24日 20:40:08 作者：
項(xiàng)目的表現(xiàn)層使用MVC+Extjs。在開(kāi)發(fā)過(guò)程中，一旦頁(yè)面顯示不正常，第一個(gè)需要排查的總是“Action是否輸出了正確的Json？”。
不用耗費(fèi)額外的精力隨時(shí)查看Json輸出
“不用耗費(fèi)額外的精力”指的是：當(dāng)需要查看Json輸出時(shí)，只要轉(zhuǎn)轉(zhuǎn)眼球（可能至少還需要點(diǎn)兩下鼠標(biāo)，恐怕）就能很快找到想看的結(jié)果。
查看Json輸出的方法很多，我們所能找的最接近這個(gè)目標(biāo)的方案是“Fiddler2+JsonViewer插件+自定義Fiddler2過(guò)濾條件”。想要查看Json輸出時(shí)，只要先將Fiddler運(yùn)行起來(lái)，然后在瀏覽器里正常操作Web頁(yè)面，就可以在Fiddler里面看到截獲的Json輸出了，效果如下圖所示。
<configuration>
<runtime>
<generatePublisherEvidence enabled="false"/>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<probing privatePath="Inspectors" />
</assemblyBinding>
</runtime>
</configuration>
注意 IE7 和 .NET Framework 被硬編碼成只要是對(duì)localhost的請(qǐng)求，就不通過(guò)代理服務(wù)器。所以像“http://localhost:8000/Default.aspx”這樣的請(qǐng)求不會(huì)被Fiddler2截獲。解決方法是：1) 將“l(fā)ocalhost”替換成“l(fā)ocalhost.”,如“http://localhost.:8000/Default.aspx”；2) 將“l(fā)ocalhost”替換成本機(jī)IP地址，如“http://172.16.75.78:8000/Default.aspx”。
現(xiàn)在，讓我們把Fiddler2運(yùn)行起來(lái)，再操作一下頁(yè)面，就可以在Fiddler2窗體左側(cè)的“Web Sessions”列表里看到一大堆請(qǐng)求/應(yīng)答。點(diǎn)擊返回Json的那一條，再點(diǎn)擊進(jìn)入右側(cè)的“Inspectors”、“Json”Tab頁(yè)，就可以了。只是，F(xiàn)iddler2默認(rèn)會(huì)把所有經(jīng)過(guò)IE的任何請(qǐng)求/應(yīng)答全都顯示出來(lái)，這樣一來(lái)，“Web Sessions”列表里的東東就嫌太多了，能不能把與Json不相干的東東全部過(guò)濾掉呢？這個(gè)并不難，只要在Fiddler2的“CustomRules”里面增加幾行代碼就可以了。
自定義過(guò)濾條件
點(diǎn)擊Fiddler2的菜單“Rules|Customize Rules...”，會(huì)自動(dòng)由記事本打開(kāi)可添加自定義規(guī)則的代碼文件。
在第81行增加如下代碼，目的是在Fiddler2的Rules菜單里增加一個(gè)“只顯示Json”的菜單項(xiàng)：
// jcl20091121
public static RulesOption("只顯示 &Json")
var m_ShowJsonOnly: boolean = false;
在OnBeforeResponse事件里增加如下代碼，意思是如果“Rules|只顯示Json”菜單項(xiàng)被選中了，就過(guò)濾掉所有Content-Type!="application/json; charset=utf-8"的應(yīng)答。
// jcl:2009-11-21
if(m_ShowJsonOnly) {
//MessageBox.Show(oSession.oResponse.headers.Item("Content-Type").ToString());
if (!oSession.oResponse.headers.ExistsAndContains("Content-Type", "application/json; charset=utf-8")) {
oSession["ui-hide"] = "hide"; // String value not important
}

現(xiàn)在“Web Sessions”列表已經(jīng)清爽多了，可是，如果我們想忙里偷閑，去博客園首頁(yè)逛逛，就會(huì)發(fā)現(xiàn)“Web Sessions”列表里面多了幾條博客園首頁(yè)的Json輸出，這是因?yàn)镕iddler2默認(rèn)會(huì)截獲所有經(jīng)由IE的請(qǐng)求/應(yīng)答。能不能讓它只顯示本機(jī)的請(qǐng)求/應(yīng)答呢？這個(gè)只需要配置一下Fiddler2的Filter選項(xiàng)就可以了，如下圖所示。
“不用耗費(fèi)額外的精力”指的是：當(dāng)需要查看Json輸出時(shí)，只要轉(zhuǎn)轉(zhuǎn)眼球（可能至少還需要點(diǎn)兩下鼠標(biāo)，恐怕）就能很快找到想看的結(jié)果。
查看Json輸出的方法很多，我們所能找的最接近這個(gè)目標(biāo)的方案是“Fiddler2+JsonViewer插件+自定義Fiddler2過(guò)濾條件”。想要查看Json輸出時(shí)，只要先將Fiddler運(yùn)行起來(lái)，然后在瀏覽器里正常操作Web頁(yè)面，就可以在Fiddler里面看到截獲的Json輸出了，效果如下圖所示。
安裝Fiddler2+JsonViewer插件
Fiddler2是一款老牌Web調(diào)試工具。下載、安裝之后，通過(guò)點(diǎn)擊“開(kāi)始|程序|Fiddler2”或點(diǎn)擊IE的菜單“工具|Fiddler2”將其運(yùn)行起來(lái)后，它會(huì)自動(dòng)把自己注冊(cè)成IE的代理服務(wù)器，從而截獲任何經(jīng)過(guò)IE的請(qǐng)求/應(yīng)答；當(dāng)關(guān)閉它時(shí)，它又會(huì)自動(dòng)把代理服務(wù)器配置取消（當(dāng)年使用Fiddler1的時(shí)候，還得自己添加代理服務(wù)器配置，很麻煩的說(shuō)）。
JsonViewer是一款查看Json對(duì)象的小工具。解壓后，可以看到3個(gè)子目錄：
- JsonView：可獨(dú)立運(yùn)行版。
- Visualizer：VS2005插件。
- Fiddler：Fiddler2插件。
我們接下來(lái)要安裝JsonViewer的Fiddler2插件。方法是，將Fiddler目錄中的所有文件復(fù)制到“Fiddler2的安裝目錄\Inspectors\”。然后修改“Fiddler2的安裝目錄\fiddler.exe.config”，如下圖所示，粗體部分是需要我們添加的配置信息。
復(fù)制代碼 代碼如下:
<configuration>
<runtime>
<generatePublisherEvidence enabled="false"/>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<probing privatePath="Inspectors" />
</assemblyBinding>
</runtime>
</configuration>
注意 IE7 和 .NET Framework 被硬編碼成只要是對(duì)localhost的請(qǐng)求，就不通過(guò)代理服務(wù)器。所以像“http://localhost:8000/Default.aspx”這樣的請(qǐng)求不會(huì)被Fiddler2截獲。解決方法是：1) 將“l(fā)ocalhost”替換成“l(fā)ocalhost.”,如“http://localhost.:8000/Default.aspx”；2) 將“l(fā)ocalhost”替換成本機(jī)IP地址，如“http://172.16.75.78:8000/Default.aspx”。
現(xiàn)在，讓我們把Fiddler2運(yùn)行起來(lái)，再操作一下頁(yè)面，就可以在Fiddler2窗體左側(cè)的“Web Sessions”列表里看到一大堆請(qǐng)求/應(yīng)答。點(diǎn)擊返回Json的那一條，再點(diǎn)擊進(jìn)入右側(cè)的“Inspectors”、“Json”Tab頁(yè)，就可以了。只是，F(xiàn)iddler2默認(rèn)會(huì)把所有經(jīng)過(guò)IE的任何請(qǐng)求/應(yīng)答全都顯示出來(lái)，這樣一來(lái)，“Web Sessions”列表里的東東就嫌太多了，能不能把與Json不相干的東東全部過(guò)濾掉呢？這個(gè)并不難，只要在Fiddler2的“CustomRules”里面增加幾行代碼就可以了。
自定義過(guò)濾條件
點(diǎn)擊Fiddler2的菜單“Rules|Customize Rules...”，會(huì)自動(dòng)由記事本打開(kāi)可添加自定義規(guī)則的代碼文件。
在第81行增加如下代碼，目的是在Fiddler2的Rules菜單里增加一個(gè)“只顯示Json”的菜單項(xiàng)：
// jcl20091121
public static RulesOption("只顯示 &Json")
var m_ShowJsonOnly: boolean = false;
在OnBeforeResponse事件里增加如下代碼，意思是如果“Rules|只顯示Json”菜單項(xiàng)被選中了，就過(guò)濾掉所有Content-Type!="application/json; charset=utf-8"的應(yīng)答。
復(fù)制代碼 代碼如下:
// jcl:2009-11-21
if(m_ShowJsonOnly) {
//MessageBox.Show(oSession.oResponse.headers.Item("Content-Type").ToString());

現(xiàn)在“Web Sessions”列表已經(jīng)清爽多了，可是，如果我們想忙里偷閑，去博客園首頁(yè)逛逛，就會(huì)發(fā)現(xiàn)“Web Sessions”列表里面多了幾條博客園首頁(yè)的Json輸出，這是因?yàn)镕iddler2默認(rèn)會(huì)截獲所有經(jīng)由IE的請(qǐng)求/應(yīng)答。能不能讓它只顯示本機(jī)的請(qǐng)求/應(yīng)答呢？這個(gè)只需要配置一下Fiddler2的Filter選項(xiàng)就可以了，如下圖所示。
