java - 无法使用 picasso 加载 url 中包含 % 的图像

Question

我在我的项目中使用 Picasso v2.5.2。它工作正常，但是，在某些情况下，url 中有一个 % 字符，在这种情况下，Picasso 会抛出错误。

String url = "http://dev.api.getmyparking.com:5000/api/v1/Containers/gmp-booking-tickets/download/AVGA3JJ%25UAB.png"; 
Picasso picasso = new Picasso.Builder(this).listener(new Picasso.Listener() {
            @Override
            public void onImageLoadFailed(Picasso picasso, Uri uri, Exception exception) {
                exception.printStackTrace();
            }
        }).build();
picasso.setLoggingEnabled(true);
picasso.load(url).placeholder(R.drawable.parking_placeholder).error(R.drawable.icn_rupee).into(mIvTicket);

以上代码报错如下:

编码 URL 似乎是一种解决方案，但是，我使用 Uri.encode 对 url 进行编码，然后将编码后的字符串提供给 Picasso，但效果不佳。

    String url = "http://dev.api.getmyparking.com:5000/api/v1/Containers/gmp-booking-tickets/download/AVGA3JJ%25UAB.png"; 
    String urlEncoded = Uri.encode(url);
            Picasso picasso = new Picasso.Builder(this).listener(new Picasso.Listener() {
                @Override
                public void onImageLoadFailed(Picasso picasso, Uri uri, Exception exception) {
                    exception.printStackTrace();
                }
            }).build();
       picasso.setLoggingEnabled(true);     
picasso.load(urlEncoded).placeholder(R.drawable.parking_placeholder).error(R.drawable.icn_rupee).into(mIvTicket);

Answer 1

试试这个，

String urlStr = "http://dev.api.getmyparking.com:5000/api/v1/Containers/gmp-booking-tickets/download/AVGA3JJ%25UAB.png";
String url = Uri.parse(urlStr)
                .buildUpon()
                .build()
                .toString();
