Now and then when you encounter a problem, you have to put on your Hacker hoodie and just go for it. That's how I discovered some of the debugging capabilities of Fiddler.
Charles is an HTTP proxy / HTTP monitor / Reverse Proxy that enables a developer to view all of the HTTP and SSL / HTTPS traffic between their machine and the Internet. This includes requests, responses and the HTTP headers (which contain the cookies and caching information).
As an iOS developer - it's difficult to capture the network calls your app is making to determine why weird things are happening. After you've determined it's not your code, the next step is determining where it's coming from. Enter network sniffing.
Fiddler is a free HTTP proxy server application. Translated to English: Fiddler is an application that you can hook up your device to (through a proxy) and watch the network traffic go back and forth. There are other tools out there, like Charles for Mac, but today we're discussing Fiddler.
Fiddler Alternative Mac
First, download Fiddler on your PC.
Configuration
You'll need to do some configuration to connect another device to the proxy.
Click Tools -> Fiddler Options -> Connections
Select the checkbox for Allow remote computers to connectFor HTTPS connections, click on the HTTPS tab under Fiddler Options.
Select the checkbox for Capture HTTPS CONNECTs, and the Decrypt HTTPS traffic checkbox.
You'll have to initiate the SSL Certificate for Fiddler too.
Click Actions -> Trust Root Certificate
Click OK
Restart Fiddler. After any changes, you must restart Fiddler.
Note: You may have to enable Fiddler to go through the firewall.
Connection Info
On the right side of the Fiddler window, you'll see an 'Online' status. If you don't - please refer to Telerik's documentation. It's great!
If you hover over your online status, you'll see the IP address at the bottom of the window. That's the IP address you'll need for the next step.
Fiddler For Mac Os
Device Setup
Go to your device's network settings, and enable a proxy.
For server, enter the IP Address from Fiddler.
For port, enter '8888' (or whatever is in the Fiddler Options -> Connections menu.)
For HTTPS:
Go to a web browser and enter '[IPADDRESS]:8888'
You should see a 'Fiddler Echo Service' page.
Download the FiddlerRoot certificate
Install & Trust the certificate
Note: It's recommended to delete the certificate when you're finished
Ta-Da!
You should now be all set to go.
Now you can capture detailed network traffic, requests and responses, and figure out where things are going awry. Use your powers for good and not evil.
