微信API参考
Platform.ts添加
declare interface Platform {
getUserInfo(): Promise<any>;
login(): Promise<any>
getFileData(fileName): Promise<any>;
writeFileData(fileName,data): Promise<any>;
}
class DebugPlatform implements Platform {
async getUserInfo() {
return { nickName: "username" }
}
async login() {
}
/**获得文件内容 */
async getFileData(fileName) {
return { key: "key" }
}
/**文件中写入 */
async writeFileData(fileName,data) {
}
}
使用
private async getFileData() {
console.log("读取");
let fileName = "score.txt";
let d = await platform.getFileData(fileName);
console.log(d);
}
private async writeFileData() {
let fileName = "score.txt";
let num = ~~(Math.random() * 100);
console.log("写入,内容是" + num);
await platform.writeFileData(fileName, num);
}
发布的微信项目中platform.js添加
fs = wx.getFileSystemManager()
getFileData(filePath) {
var self = this;
return new Promise((resolve, reject) => {
self.fs.readFile({
filePath: `${wx.env.USER_DATA_PATH}/` + filePath,
encoding: "utf8",
success: (data) => {
resolve(data.data);
},
fail: (errMsg) => {
console.log(errMsg);
self.fs.writeFileSync(`${wx.env.USER_DATA_PATH}/` + filePath, '0', 'utf8');
},
complete: () => { console.log("读取完成") }
});
})
}
writeFileData(fileName, num) {
var self = this;
return new Promise((resolve, reject) => {
self.fs.writeFileSync(`${wx.env.USER_DATA_PATH}/` + fileName, num , 'utf8');
})
}
