Glide FileNotFoundException:从Internet加载图像时没有内容提供者

Question

我做了自己的休息api,现在它只有端点,我显示了一些图像.这是它在spring boot应用程序中的外观

@GetMapping("/image/{name:.+}")
    public byte[] getImage(@PathVariable(value = "name") String name) {
        return storageService.loadFileAsByteArray(name);
    }

这是存储服务方法

 public byte[] loadFileAsByteArray(String filename) {
            Resource resource = loadFile(filename);
            try {
                return IOUtils.toByteArray(resource.getInputStream());
            } catch (IOException e) {
                e.printStackTrace();
            }
            return null;
        }

在这里我在我的Android应用程序中做了什么

Glide.with(context!!.applicationContext).load("http://myipaddress/api/image/myimage.jpg").into(it)

所以我从滑翔中得到了什么

根本原因(2/2)

java.io.FileNotFoundException: No content provider: http://myipaddress/api/image/myimage.jpg

但如果我在浏览器中找到该链接,一切正常.为什么会这样？

Answer 1

如果您在目标API 28，并出现在Android 9这个问题，并开始与URL http您的问题是交通明文提到这里的网络安全配置

从Android 9.0（API级别28）开始，默认情况下禁用明文支持。

确保所有连接均始终通过HTTPS进行，以保护敏感流量免受恶意网络的攻击。

如果您想退出明文流量

仅在您的应用程序清单上添加此属性

<application
 . 
 android:usesCleartextTraffic="true"
 .

 >

 </application>

如果您想让特定的域拥有规则

创建文件res / xml / network_security_config.xml

<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
    <domain-config cleartextTrafficPermitted="false">
    <domain includeSubdomains="true">secure.example.com</domain>
</domain-config>
</network-security-config>

AndroidManifest.xml-

<?xml version="1.0" encoding="utf-8"?>
<manifest ...>
    <uses-permission android:name="android.permission.INTERNET" />
    <application
        ...
        android:networkSecurityConfig="@xml/network_security_config"
        ...>
        ...
    </application>
</manifest>
