ceisum加载默认地形数据并解决401错误

加载ceisum默认地形数据

var viewer = new Cesium.Viewer(‘cesiumContainer’, {
terrainProvider : Cesium.createWorldTerrain({
requestWaterMask : true,
requestVertexNormals : true
});
});

如果报错：401
在前面加上var viewer 的初始化代码前面加上：
Cesium.Ion.defaultAccessToken = ‘eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJqdGkiOiI1NWI5MGUzNi1mYWI3LTQzY2QtOGI0Ni0xZWYyNTAxNGM4N2MiLCJpZCI6MTI1OTgsInNjb3BlcyI6WyJhc3IiLCJnYyJdLCJpYXQiOjE1NjE0NDkyNTV9.hBH0PGSnKErc_yNhIePASUkr3QPDoo0KDX9uLpNBUns’;
