No extra effort to view JSON output at any time
"No extra effort" means that when you need to look at the JSON output, just turn the eyeball (and maybe at least two more clicks) to find the result quickly.
There are a lot of ways to view JSON output, and the closest we can get to this goal is "Fiddler2+jsonviewer plugin + custom Fiddler2 filter conditions." To view the JSON output, just run the fiddler first, and then in the browser normal operation of the Web page, you can see in the Fiddler of the captured JSON output, the effect shown in the following figure.
Installing the Fiddler2+jsonviewer Plugin
Fiddler2 is a veteran web debugging tool. After downloading and installing, click "Start | program | Fiddler2 "or click IE Menu" tool | Fiddler2 "It will automatically register itself as an IE proxy server, so as to intercept any request/response through IE; when you close it, it automatically cancels the proxy server configuration (when you use Fiddler1, you have to add your own proxy server configuration, Very troublesome to say).
Jsonviewer is a small tool for viewing JSON objects. After decompression, you can see 3 subdirectories:
-Jsonview: Can be run independently version.
-visualizer:vs2005 plugin.
-Fiddler:fiddler2 plugin.
We're going to install the Jsonviewer Fiddler2 plugin next. To do this, copy all the files in the Fiddler directory to the Fiddler2 installation directory \inspectors\. Then modify the "Fiddler2 installation directory \fiddler.exe.config", as shown in the following figure, and the bold part is the configuration information we need to add.
Copy Code code as follows:
<configuration>
<runtime>
<generatepublisherevidence enabled= "false"/>
<assemblybinding xmlns= "Urn:schemas-microsoft-com:asm.v1" >
<probing privatepath= "Inspectors"/>
</assemblyBinding>
</runtime>
</configuration>
Note that the IE7 and the. NET Framework are hard-coded into a proxy server as long as it is a request to localhost. So requests like "http://localhost:8000/Default.aspx" are not intercepted by Fiddler2. The workaround is: 1 replace "localhost" with "localhost.", such as "http://localhost.:8000/Default.aspx" and 2, substituting "localhost" for the cost machine IP address, such as "http:// 172.16.75.78:8000/default.aspx ".
Now let's run the Fiddler2 and then manipulate the page to see a bunch of requests/responses in the Web Sessions list on the left side of the Fiddler2 form. Click to return to JSON, and then click the "inspectors" and "Json" tab on the right side to go. Just, Fiddler2 by default will all go through IE any request/answer all show out, so, "Web Sessions" list of Dongdong too much, can not all the things with JSON filter out? This is not difficult, just add a few lines of code to the Fiddler2 "Customrules".
Custom filter conditions
Click on the Fiddler2 menu "rules| Customize rules ... "Automatically opens a code file that you can add a custom rule to by Notepad.
Add the following code on line 81st to add a "JSON-only" menu item to the FIDDLER2 rules menu:
jcl20091121
public static Rulesoption ("show &json Only")
var M_showjsononly:boolean = false;
Add the following code in the Onbeforeresponse event, which means that if the "rules| only show JSON" menu item is selected, it filters out all content-type!= "Application/json;" Charset=utf-8 "answer.
Copy Code code as follows:
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
}
}

Import Fiddler;

Now the "Web Sessions" list has been much more refreshing, but, if we want to sneak in and visit the home page of the blog, we will find that the "Web Sessions" list contains several more than a few blog home page JSON output, this is because FIDDLER2 will intercept all requests via IE by default Answer Would it be possible for it to show only the local request/response? This only needs to be configured with the FIDDLER2 filter option, as shown in the following figure.
