An all-optical method for directly reconstructing the spectral phase ofisolated attosecond pulse (IAP) has been proposed recently [New J. Phys. 25,083003 (2023)]. This method is based on the high-harmonic generation (HHG)streaking spectra generated by an IAP and a time-delayed intense infrared (IR)laser, which can be accurately simulated by an extended quantitativerescattering model. Here we extend the retrieval algorithm in this method tosuccessfully retrieve the spectral phase of an shaped IAP, which has a spectralminimum, a phase jump about $\pi$, and a "split" temporal profile. We thenreconstruct the carrier-envelope phase of IR laser from HHG streaking spectra.And we finally discuss the retrieval of the phase of high harmonics by theintense IR laser alone using the Fourier transform of HHG streaking spectra.
