Fiddler简介与Firebug

Fiddler contains web sessions (left), request (right top) and response windows (right bottom).
Sometimes, it can only capture traffic in IE
   

           1. Build a POST request

HTTP method: POST

URL: http://www.choicehotels.com/ires/en-US/html/Availability

Request Header (Required for POST): Content-Type: application/x-www-form-urlencoded

Request Body (Post data):

month=3&day=28&depart_month=3&depart_day=30&srp=RACK&hotel=NY618&sid=&nadult=1&nchild=0&xtrabed=none&count=1&dates_rqd=true&createarrivalcookie=yes

/*Booking data range: 3/28-3/30*/

Then Click Execute and the result will show up in the web session

  2. Analyze a POST request

Click the web session (left in Fiddler)

Request (right top):

I.                    Check the request headers here:

II.                  Check the request body here:

Response (right bottom):

3. How to find out the HTTP request to get the info we want

Take choice hotels for example: http://www.choicehotels.com/. The target is to get the rates for specific hotels given a data range.

a)      Search the hotels by zipcode (07302) at homepage

b)      Click one hotel in the result page

c)       In the detail page for that hotel, click Rates tab

d)      Update the check-in & check-out dates

You will see the http://www.choicehotels.com/ires/en-US/html/Availability with POST data by Fiddler.

Fiddler还可以用于捕捉http request，具体参见Fiddler捕捉手机app的http request
