Cordova相机插件不启动相机 [英] Cordova camera plugin not launching camera

问题描述

我创建了一个Ionic应用程序，我需要相机功能，以便用户可以拍摄照片并将其发送到Web服务。我已遵循Ionic的以下指南。

I've created an Ionic app and I need the camera functionality so that a user can take a picture and send it to a webservice. I've followed the following guide by Ionic.

基本上你只需将 cd 插入到你的应用程序中即可。

Basically you just cd into your applicatoin

cd myApp

然后您运行

cordova plugin add org.apache.cordova.camera

插件已经安装，你可以在你的应用程序中调用它的功能（因为根据Cordova， navigator.camera 是一个全局对象）。在我的情况下，我只是在我的控制器之一，使用 ng-click 按钮单击后调用以下函数：

and once the plugin has been installed, you can invoke it's functionality where ever in your app (because according to Cordova, navigator.camera is a global object). In my case I'm just doing it in one of my controllers where the following function gets called after a button click using ng-click :

$scope.takePhoto = function() {

      navigator.camera.getPicture(function(imageURI) {

        // imageURI is the URL of the image that we can use for
        // an <img> element or backgroundImage.

      }, function(err) {

        // Ruh-roh, something bad happened


      }, cameraOptions);

    }

但它什么也不做。 Ionic说我必须做一个'T'，没有更多。还有什么我应该做吗？可能是编辑 config.xml ？这可能值得一提，这是我第一次尝试使用任何类型的Cordova插件。

But it does nothing.. Now I've followed what Ionic said I must do to a 'T' and nothing more. Is there anything else I should be doing? Editing the config.xml perhaps? It's probably worth mentioning that this is the first time I've attempted in using a Cordova plugin of any sort.

推荐答案

使用以下代码解决此问题，

I just resolved this problem by using below code,

$scope.takePhoto = function() {
    navigator.camera.getPicture(onSuccess, onFail, {
        quality: 75,
        targetWidth: 320,
        targetHeight: 320,
        destinationType: 0
    });
   function onSuccess(imageData) {
         alert('onSuccess');
         console.log("data:image/jpeg;base64,"+imageData);
    }

    function onFail(message) {
        alert('Failed because: ' + message);
    }
};

imageData 是您捕获的图像的src

The imageData is the src of your captured image
