Installation and introduction of fiddler subcontract software.

Compared with the three APP package grabbing tools, the operating system supported by the name of the operating system is difficult and easy to debug using the platform. On the fiddlerWindows/linux/mac web side, there are generally more mitmproxyWindows/Mac/Linux web ends on the app side, and there are generally more packetCapture on the app side and less fiddler on the Android APP side.

History

Fiddler is written in C #, it contains a simple but powerful JScript .NET-based event scripting subsystem, it is very flexible, can support many http debugging tasks, and can be extended using the. Net framework language.

Introduction

Fiddler is a web debugging agent platform that can monitor and modify web data flows.

Powerful function

Advantages

You can view the web data flow between all browsers, client applications or services manually or automatically modify any request and response that can decrypt the https data stream for viewing and modification

Shortcoming

Fiddler only supports protocols related to http,https,ftp,websocket data streams and cannot monitor or modify other data, such as pop3,smtp. Fiddler cannot process data that requests and responses exceed the 2gb. download

Function introduction

Interface function

Support for https

The request sent out is captured by fiddler, and then encrypted and forwarded by the certificate of fiddler. The server completes the decryption and sends it to fiddler,fiddler for decryption and then tells it to the client in plaintext. Fiddler acts as a middleman in the middle.

Four types

All requests browser requests remove all browser requests remote client requests (this column is required by APP crawlers)

The port is arbitrary, as long as it does not conflict with the existing port

Remote calls must be allowed

The next step is to install the google browser plug-in, provided that "× ×"

Chrome://apps/

Install the plug-in: switchyomega

Add the scene of swichyomega

Google browser selects the corresponding fiddler

The point is: after the fiddler is set, it needs to be restarted.

Log in to baidu to view the effect

The browser logs in to the google browser, and then fiddler starts to work, as long as the google browser opens the scene in swichyomega, starts decode, and transcodes automatically. Generally, Raw is used for viewing, and see how request and response are used.

PS: this is the crawl setting in the fiddler on the web. Add the crawl setting on the app side later. The key point is to get familiar with this software first.
