首先，你得理解为什么浏览器要限制跨域：
所以，浏览器限制了跨域请求。
问：那么，我们开发时，想要访问线上接口怎么办？
答：我们可以用 vite 之类 nodejs 的代理功能，通过代理访问线上接口，代理一词的意思是我们访问本地的接口，代理服务器通过本地程序（非浏览器）转发到线上接口。
问：如果我们确实有线上项目的跨域请求的需求怎么办？
答：我们可以在服务器设置 Access-Control-Allow-Origin ，将我们自己人加入白名单。

本文一步一步教你如何在小程序中使用最新版的OpenCV
安装基础工具
pacman -S base-devel cmake gitgit clone https://github.com/juj/emsdk.git
cd emsdk
./emsdk install 2.0.10
./emsdk activate 2.0.10
source ./emsdk_env.sh进入 https://opencv.org/releases/ 页面下载opencv最新版源码，并解压缩，并进入解压缩后文件夹
修改platforms/js/opencv_js.config.py文件根据情况，去掉不用的模块
# white_list = makeWhiteList([core, imgproc, objdetect, video, dnn, features2d, photo, aruco, calib3d])
white_list = makeWhiteList([core, imgproc])默认OpenCV4会将wasm以base64存到js文件，输出单独wasm文件便于用于微信小程序
打开modules/js/CMakeLists.txt，去掉 SINGLE_FILE参数
# set(EMSCRIPTEN_LINK_FLAGS "${EMSCRIPTEN_LINK_FLAGS} -s MODULARIZE=1 -s SINGLE_FILE=1")
set(EMSCRIPTEN_LINK_FLAGS "${EMSCRIPTEN_LINK_FLAGS} -s MODULARIZE=1")微信小程序不支持eval()和new Function()等动态执行函数，在modules/js/CMakeLists.txt中，增加DYNAMIC_EXECUTION的编译参数屏蔽这些函数的输出
# set(EMSCRIPTEN_LINK_FLAGS "${EMSCRIPTEN_LINK_FLAGS} -s MODULARIZE=1 -s SINGLE_FILE=1")
set(EMSCRIPTEN_LINK_FLAGS "${EMSCRIPTEN_LINK_FLAGS} -s MODULARIZE=1")
set(EMSCRIPTEN_LINK_FLAGS "${EMSCRIPTEN_LINK_FLAGS} -s DYNAMIC_EXECUTION=0")emcmake python ./platforms/js/build_js.py -hemcmake python ./platforms/js/build_js.py build_wasm --build_wasm --build_testbuild_wasm\bin目录生成了opencv.js,opencv_js.wasm,tests.html文件
brotli -o build_wasm/bin/opencv_js.wasm.br build_wasm/bin/opencv_js.wasmnpm i -g http-server
http-server build_wasm/bin/在浏览器打开 http://127.0.0.1:8080/tests.html 可以查看测试结果
opencv.js适配微信小程序修改前先将opencv.js格式化一下，微信小程序不支持通过url获取wasm，修改下instantiateAsync方法的else分支里面的代码，让读小程序项目下的opencv_js.wasm文件
function instantiateAsync() {
if (
!wasmBinary &&
typeof WebAssembly.instantiateStreaming === "function" &&
!isDataURI(wasmBinaryFile) &&
!isFileURI(wasmBinaryFile) &&
typeof fetch === "function"
) {
return fetch(wasmBinaryFile, { credentials: "same-origin" }).then(
function (response) {
var result = WebAssembly.instantiateStreaming(response, info);
return result.then(
receiveInstantiatedSource,
function (reason) {
err("wasm streaming compile failed: " + reason);
err("falling back to ArrayBuffer instantiation");
return instantiateArrayBuffer(receiveInstantiatedSource);
}
);
}
);
} else {
// return instantiateArrayBuffer(receiveInstantiatedSource);
var result = WebAssembly.instantiate("/opencv/opencv_js.wasm.br", info);
return result.then(
receiveInstantiatedSource,
function (reason) {
err("wasm streaming compile failed: " + reason);
err("falling back to ArrayBuffer instantiation");
return instantiateArrayBuffer(receiveInstantiatedSource);
}
);
}
}这些方法定义在modules\js\src\helpers.js文件中，修改后重新编译和生成wasm文件即可
OpenCV.jsconst app = getApp()
WebAssembly = WXWebAssembly;
let cv = require('../../opencv/opencv.js');
Page({
onLoad: function (options) {
if (cv instanceof Promise) {
cv.then((target) => {
console.log(target);
})
} else {
console.log(cv);
}
}
}) 页面

一套微信小程序抽奖平台(包含全部前后端源码)
功能介绍
1、口令抽奖： 大家都知道小程序的限制颇多，不能引导回公众号，即使关联跳转小程序，也有数量限制。口令抽奖一来可以限制参与抽奖的人，二来可以通过口令提示引导回公众号下发口令，带动关注。
2、限定地点： 我希望这个小程序未来也可以帮助线下的商户发起抽奖活动，那么做一个参与的位置电子围栏是很有必要的。
3、限定性别： 不多解释
4、条码解锁： 这个的思路也很好玩，让抽奖活动需要触发扫描特定的条形码方可参与。那么自然特别适合快速消费品品牌来玩。
5、RP币

使用JavaScript的原型特性，这样就可以从画布上下文中调用该函数
CanvasRenderingContext2D.prototype.wrapText = function (text, x, y, maxWidth, lineHeight) {
var lines = text.split("\n");
for (var i = 0; i < lines.length; i++) {
var words = lines[i].split(' ');
var line = '';
for (var n = 0; n < words.length; n++) {
var testLine = line + words[n] + ' ';
var metrics = this.measureText(testLine);
var testWidth = metrics.width;
if (testWidth > maxWidth && n > 0) {
this.fillText(line, x, y);
line = words[n] + ' ';
y += lineHeight;
}
else {
line = testLine;
}
}
this.fillText(line, x, y);
y += lineHeight;
}
}
用法
var myCanvas = document.getElementById("myCanvas");
var ctx = myCanvas.getContext("2d");
ctx.fillStyle = "black";
ctx.font = "12px sans-serif";
ctx.textBaseline = "top";
ctx.wrapText("Hello\nWorld!",20,20,160,16);
