在PyQGIS QGIS 3.10中从CSV加载点图层

from qgis.core import QgsVectorLayer, QgsField, QgsPointXY, QgsProject
from qgis.PyQt.QtCore import QVariant

csv_file = '/path/to/your/csv/file.csv'
layer_name = 'Point Layer'

layer = QgsVectorLayer('Point?crs=epsg:4326', layer_name, 'memory')
provider = layer.dataProvider()

with open(csv_file, 'r') as file:
    headers = file.readline().strip().split(',')
    fields = []
    for header in headers:
        field = QgsField(header, QVariant.String)
        fields.append(field)
    provider.addAttributes(fields)
    layer.updateFields()

    for line in file:
        attributes = line.strip().split(',')
        feature = QgsFeature()
        feature.setFields(layer.fields())
        geometry = QgsPointXY(float(attributes[0]), float(attributes[1]))
        feature.setGeometry(geometry)
        feature.setAttributes(attributes)
        provider.addFeature(feature)

# 将图层添加到项目中
QgsProject.instance().addMapLayer(layer)
