java - 无法通过 placeholder.com url 加载图像

Question

遇到了一个奇怪的问题，试图从这里通过模型内部的 url 下载任何照片 -> https://jsonplaceholder.typicode.com/photos ，例如这个“https://via.placeholder.com/150/92c952”但是得到错误:

Glide: Load failed for https://via.placeholder.com/600/92c952 with size [788x788]
class com.bumptech.glide.load.engine.GlideException: Failed to load resource
There was 1 cause:
java.io.FileNotFoundException(https://via.placeholder.com/600/92c952)
 call GlideException#logRootCauses(String) for more detail
  Cause (1 of 1): class com.bumptech.glide.load.engine.GlideException: Fetching data failed, class java.io.InputStream, REMOTE
There was 1 cause:
java.io.FileNotFoundException(https://via.placeholder.com/600/92c952)
 call GlideException#logRootCauses(String) for more detail
    Cause (1 of 1): class com.bumptech.glide.load.engine.GlideException: Fetch failed

 call GlideException#logRootCauses(String) for more detail
      Cause (1 of 1): class java.io.FileNotFoundException: https://via.placeholder.com/600/92c952

顺便说一句，如果我试图从其他链接加载图像，例如这个 -> https://avatars.mds.yandex.net/get-pdb/1088712/8b19d278-0b9b-46f8-89e4-66f5541efc55/s1200?webp=false

一切正常。另外我想提一下，Picasso、Fresco 等没有加载图像。使用

InputStream inputStream = new URL(urlLik).openStream();
bitmap = BitmapFactory.decodeStream(inputStream);

也无济于事。
在此先感谢，真的在这个问题上堆叠。

使用 glide 加载图像的代码:

 RequestOptions requestOptions = RequestOption.placeholderOf(R.drawable.white_background).timeout(15000)
                    .error(R.color.grey);
        Glide.with(application)
                    .setDefaultRequestOptions(requestOptions).load("https://via.placeholder.com/150/92c952")
.placeholder(R.drawable.white_background).dontAnimate().into(image);

Answer 1

此问题与 User-Agent header 参数有关。和Glide无关，都是https://via.placeholder.com .您可以通过 GlideUrl 创建 URL 并添加 User-Agent header 来解决此问题。

GlideUrl url = new GlideUrl("https://your-url.com", new LazyHeaders.Builder()
            .addHeader("User-Agent", "your-user-agent")
            .build());
