如何使用PyQGIS將項目加載到QGIS？

Question

我使用PyQGIS Cookbook學習PyQGIS，併購買了PyQGIS程序員指南。我已經能夠使用小腳本加載圖層，但沒有運氣將項目加載到QGIS中。我不斷收到第13行的'SyntaxError：invalid syntax'。我正在使用QGIS中的Python控制檯並鍵入'import _loadproject'來啓動腳本。

有人可以指出我要去哪裏嗎？

"""Load Project: This is to test loading a project.""" 

from PyQt4.QtGui import * 
from PyQt4.QtCore import * 
from qgis.core import * 
from qgis.utils import iface 

class ProjectScript: 

def __init__(self, iface): 
    self.iface = iface 

def load_project(self) 
    project = QgsProject.instance() \ 
    project.read(QFileInfo('S:/SOCAL/Section_28/SOCAL_CK47/Control_Data/SOCAL_CK47_project.qgs')) 
    print project.fileName 'S:/SOCAL/Section_28/SOCAL_CK47/Control_Data/SOCAL_CK47_project.qgs' 

def run_script(iface): 
"""Run the script by loading and calling LoadProject methods.""" 
fs = ProjectScript(iface) 
fs.load_project() 

Answer 1

檢查這個例子：

from PyQt4.QtGui import * 
from PyQt4.QtCore import * 
from qgis.core import * 
from qgis.utils import iface 

class ProjectScript: 

    def __init__(self, iface): 
     self.iface = iface 

    def load_project(self): 
     project = QgsProject.instance() 
     project.read(QFileInfo('S:\\SOCAL\\Section_28\\SOCAL_CK47\\Control_Data\\SOCAL_CK47_project.qgs')) 
     print project.fileName() 

    def run_script(iface): 
     """Run the script by loading and calling LoadProject methods.""" 
     fs = ProjectScript(iface) 
     fs.load_project() 

保存這個腳本，例如ProjectScript.py使用Python控制檯，execute.The下一個圖像顯示效果。
