碼 -

getImage(){ 
    var options = { 
     sourceType: Camera.PictureSourceType.PHOTOLIBRARY 
    }; 
    Camera.getPicture(options).then((imageData) => { 
     // imageData is either a base64 encoded string or a file URI 
     // If it's base64: 
     let base64Image = "data:image/jpeg;base64," + imageData; 
    }, (err) => { 
    }); 

    }; 

Answer 1

我剛看了一下離子本機camera.ts代碼 - here。

sourceType定義如下：

sourceType ?: number;

爲不同PictureSourceType的數字給出如下：

PHOTOLIBRARY：0， CAMERA：1， SAVEDPHOTOALBUM：2

那麼你爲什麼不嘗試用sourceType的：0

希望這可以幫助你。謝謝。

Answer 2

我有完全相同的問題，並解決它。 問題：

public camera: Camera; 
constructor(public navCtrl: NavController, public navParams: NavParams) {} 

溶液：

constructor(public navCtrl: NavController, public navParams: NavParams, public camera: Camera) {}
