ng-img-crop插件怎么发送图片，php怎么接收，

ng-img-crop插件可以在前端进行图片裁剪，然后将裁剪后的图片以Base64编码的形式发送到后端服务器。在后端PHP中，可以使用$_POST或$_FILES数组来接收这个Base64编码的图片数据。 具体来说，可以在前端使用以下代码将裁剪后的图片以Base64编码的形式发送到后端： ```javascript // 获取裁剪后的图片数据 var croppedImage = $scope.croppedImage; // 将图片数据转换为Blob对象 var blob = data[uri](https://geek.csdn.net/educolumn/00029aadd70cd24e60e5a206bbad5f06?spm=1055.2569.3001.10083)toBlob(croppedImage); // 创建FormData对象 var formData = new FormData(); formData.append('image', blob); // 发送POST请求 $http.post('upload.php', formData, { headers: {'Content-Type': undefined}, transformRequest: angular.identity }).success(function(data){ console.log(data); // 将Data URI格式的图片数据转换为Blob对象 function dataURItoBlob(dataURI) { var byte[string](https://geek.csdn.net/edu/8802d631b97a4a6af1f4d0bbf8527465?dp_token=eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpZCI6NDQ0MDg2MiwiZXhwIjoxNzA3MzcxOTM4LCJpYXQiOjE3MDY3NjcxMzgsInVzZXJuYW1lIjoid2VpeGluXzY4NjQ1NjQ1In0.RrTYEnMNYPC7AQdoij4SBb0kKEgHoyvF-bZOG2eGQvc&spm=1055.2569.3001.10083) = atob(dataURI.split(',')[1]); var ab = new ArrayBuffer(byte[string](https://geek.csdn.net/edu/8802d631b97a4a6af1f4d0bbf8527465?dp_token=eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpZCI6NDQ0MDg2MiwiZXhwIjoxNzA3MzcxOTM4LCJpYXQiOjE3MDY3NjcxMzgsInVzZXJuYW1lIjoid2VpeGluXzY4NjQ1NjQ1In0.RrTYEnMNYPC7AQdoij4SBb0kKEgHoyvF-bZOG2eGQvc&spm=1055.2569.3001.10083).length); var ia = new Uint8Array(ab); for (var i = 0; i < byte[string](https://geek.csdn.net/edu/8802d631b97a4a6af1f4d0bbf8527465?dp_token=eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpZCI6NDQ0MDg2MiwiZXhwIjoxNzA3MzcxOTM4LCJpYXQiOjE3MDY3NjcxMzgsInVzZXJuYW1lIjoid2VpeGluXzY4NjQ1NjQ1In0.RrTYEnMNYPC7AQdoij4SBb0kKEgHoyvF-bZOG2eGQvc&spm=1055.2569.3001.10083).length; i++) { ia[i] = byte[string](https://geek.csdn.net/edu/8802d631b97a4a6af1f4d0bbf8527465?dp_token=eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpZCI6NDQ0MDg2MiwiZXhwIjoxNzA3MzcxOTM4LCJpYXQiOjE3MDY3NjcxMzgsInVzZXJuYW1lIjoid2VpeGluXzY4NjQ1NjQ1In0.RrTYEnMNYPC7AQdoij4SBb0kKEgHoyvF-bZOG2eGQvc&spm=1055.2569.3001.10083).charCodeAt(i); return new Blob([ab], {type: 'image/jpeg'}); ```
