android studio 重写onCreate将assets包下的请求过滤ssl证书

Android Studio中,如果你想在重写`onCreate()`方法时处理从Assets目录加载文件并过滤SSL证书,通常是在网络请求库如OkHttp、Volley或者Retrofit中实现。这里以OkHttp为例:
首先,你需要创建一个自定义的OkHttpClient实例,并在构造函数中添加一个`Intercepter`来处理SSL证书验证。在`onCreate()`里,你可以这样做:
```java
// 创建OkHttpClient实例时添加自定义拦截器
OkHttpClient client = new OkHttpClient.Builder()
.addInterceptor(new Interceptor() {
@Override
public Response intercept(Chain chain) throws IOException {
Request originalRequest = chain.request();
// 从Assets目录读取证书文件
InputStream certInputStream = getAssets().open("your_certificate.pem");
try (CertificateParser parser = CertificateParser.getInstance()) {
Certificate certificate = parser.parse(certInputStream);
X509TrustManager trustManager = new X509TrustManager() {
@Override
public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {
// 如果证书合法,信任它
if (certificate.equals(chain[0])) { // 这里假设你只接受一个证书
chain[0] = certificate;
}
}
@Override
public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {
checkClientTrusted(chain, authType); // 对于服务器也应用同样的逻辑
}
@Override
public X509Certificate[] getAcceptedIssuers() {
return null; // 返回空数组表示只信任自定义的证书
}
};
SSLContext sslContext = SSLContext.getInstance("TLS");
sslContext.init(null, new TrustManager[]{trustManager}, null);
SSLSocketFactory sslSocketFactory = sslContext.getSocketFactory();
return chain.proceed(sslSocketFactory.createSocket(chain.socket(), originalRequest.url().host(), originalRequest.url().port(), true));
} finally {
certInputStream.close();
}
}
})
.build();
// 使用自定义的client发起网络请求
YourApiService yourApi = YourApiService.create(client);
yourApi.yourMethod(...);
```
在这个例子中,你需要替换`"your_certificate.pem"`为你实际资产文件名,并根据实际需求调整证书验证逻辑。
