微信小程序上传图片语音至七牛云

将本地资源上传到服务器。客户端发起一个 HTTPS POST 请求&＃xff0c;其中 content-type 为 multipart/form-data。

以上传图片为例

示例代码&＃xff1a;

wx.chooseImage({success(res) {const tempFilePaths &＃61; res.tempFilePathswx.uploadFile({url: &＃39;https://example.weixin.qq.com/upload&＃39;, // 仅为示例&＃xff0c;非真实的接口地址filePath: tempFilePaths[0],name: &＃39;file&＃39;,formData: {user: &＃39;test&＃39;},success(res) {const data &＃61; res.data// do something}})}
})

后台接口处理接受数据

//图片上传七牛云接口public function UploadFile(){$param &＃61; request()->param();$file&＃61;request()->file(&＃39;file&＃39;);$controller&＃61;&＃39;index&＃39;;$accKey&＃61;&＃39;you key&＃39;;$secret&＃61;&＃39;you sercret&＃39;;$space&＃61;&＃39;qqcard&＃39;;$do&＃61;&＃39;10088.cn&＃39;;$img &＃61; new Upload();$url &＃61; $img->uploadImg($file,$controller,$accKey,$secret,$space,$do);$filePath &＃61; $image->getRealPath();return json([&＃39;url&＃39;&＃61;>$url]); }
