CdpHar

class · namespace z3n7 · source Traffic/CdpHar.cs

public sealed class CdpHar : IDisposable

HAR recorder that talks to the instance browser over its own DevTools endpoint (the browser writes the port to <user-data-dir>\DevToolsActivePort). Does not depend on Tab.GetTraffic. Records only what happens after Start().

Properties#

Count#

public int Count { get; }

source

Number of recorded entries.

DevToolsPort#

public int DevToolsPort { get; }

source

DevTools port of the browser.

IsAlive#

public bool IsAlive { get; }

source

Whether the DevTools connection is open.

LastError#

public string LastError { get; }

source

Last error of the background receive loop, or null.

Methods#

Clear#

public void Clear()

source

Forgets all recorded entries.

Connect#

public static CdpHar Connect(int devToolsPort)

source

Recorder bound to an explicit DevTools port (not registered per instance).

Dispose#

public void Dispose()

source

Closes the DevTools connection.

For#

public static CdpHar For(Instance instance)

source

Running recorder for this instance or null.

ResolveDevToolsPort#

public static int ResolveDevToolsPort(Instance instance)

source

Finds the DevTools port of the instance's browser from DevToolsActivePort files: the instance profile folder, the ProjectMaker browser folder and ZennoPoster's Trash\Profiles\*. The profile's own port wins when it is live; otherwise the only live candidate; otherwise the one whose page URL equals ActiveTab.URL.

Returns: The port. Throws InvalidOperationException when no live browser or several matching ones are found.

Save#

public int Save(string path, string urlRegex = null, int waitBodiesMs = 3000)

source

Writes the recorded traffic to a HAR 1.2 file (missing folders are created, an existing file is replaced).

Returns: Number of entries written.

Start#

public static CdpHar Start(Instance instance)

source

Starts (or returns the running) recorder for this instance.

Stop#

public static void Stop(Instance instance)

source

Stops and forgets the recorder of this instance, if any.

Fields#

CommandTimeoutMs#

public int CommandTimeoutMs;

source

Timeout for connecting and for each DevTools command, ms.

MaxBodyBytes#

public long MaxBodyBytes;

source

Response bodies larger than this (encoded size) are not fetched.

MaxEntries#

public int MaxEntries;

source

Most entries kept; the oldest are dropped beyond it.
