How can I use Fiddler to check the response from a web server. I could easily check the GET method by pasting the url to the field in Request Builder and get the response back in xml/json. There is an option POST, however I don't know how can I pass the parameters to the POST.
For example:
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://www.google.com/accounts/ClientLogin");
request.Method = "POST";
string postData = "accountType=HOSTED_OR_GOOGLE";
postData += "&Email=yourusername@gmail.com";
postData += "&Passwd=yourpassword";
postData += "&service=finance";
postData += "&source=test-test-.01";
How can I pass my Data into this POST method in Fiddler to get the response?
The simplest way to do this is to have Fiddler capture an instance of this request and drag/drop that session onto the Request builder.
But generating a post yourself isn't hard. Set the RequestBuilder's method to POST, add a header:
Content-Type: application/x-www-form-urlencoded
And put in the Request Body the text of the post:
accountType=HOSTED_OR_GOOGLE&Email=yourusername@gmail.com&Passwd=yourpassword&service=finance&source=test-test-.01
Step 1: Composer with Http Post, URL, Header and Body Step 2: And Result console.log at Server with Json
