android - 如何创建 XWalk WebResourceResponse？

Question

我正在寻找一种创建XWalkWebResourceResponse 的方法。我的案例如下。

我正在创建将拦截所有网络请求的自定义 XWalkResourceClient 客户端。所有应该被拦截的请求都会作为抽象包装器返回 - AppWebResourceResponse。

public final class CrossWebViewClient extends XWalkResourceClient {
    // other fields and constructor

    CrossWebResourceResponseMapper responseMapper;

    @Override
    public XWalkWebResourceResponse shouldInterceptLoadRequest(XWalkView view, XWalkWebResourceRequest request) {
        AppWebResourceRequest mappedRequest = requestMapper.toGenericRequest(request);
        AppWebResourceResponse interceptedResponse = requestInterceptor.shouldInterceptRequest(mappedRequest);
        if (interceptedResponse == null) {
            return super.shouldInterceptLoadRequest(view, request);
        }
        return responseMapper.toTargetResponse(interceptedResponse);
    }    
}

最后一步。我必须使 AppWebResourceResponse 适应 XWalkWebResourceResponse，这是我遇到问题的地方。

public class CrossWebResourceResponseMapper implements AppWebResourceResponse.Mapper<XWalkWebResourceResponse>  {
    @Override
    public XWalkWebResourceResponse toTargetResponse(final AppWebResourceResponse appResponse) {
        String mimeType = appResponse.getMimeType();
        String encoding = appResponse.getEncoding();
        int statusCode = appResponse.getStatusCode();
        String reasonPhrase = appResponse.getReasonPhrase();
        Map<String, String> headers = appResponse.getResponseHeaders();
        InputStream data = appResponse.getData();


        // ??? how to create response object?
        XWalkWebResourceResponse response;

        response.setMimeType(mimeType);
        response.setEncoding(encoding);
        response.setStatusCodeAndReasonPhrase(statusCode, reasonPhrase);
        response.setResponseHeaders(headers);
        response.setData(data);
        return response;
    }
}

根据 API 有公共(public)构造函数 new XWalkWebResourceResponse(bridge) 使用桥对象，但我未能找到检索特定桥(org.xwalk.core.internal.XWalkWebResourceResponseBridge)的方法。

在哪里可以获取XWalkWebResourceResponseBridge？

根据 Xiaofeng可以使用 XWalkResourceClient 对象创建 XWalkWebResourceResponse 对象。

public class XWalkWebResourceResponseMapper {
    public XWalkWebResourceResponse toTargetResponse(XWalkResourceClient client, AppWebResourceResponse appResponse) {
        String mimeType = appResponse.getMimeType();
        String encoding = appResponse.getEncoding();
        int statusCode = appResponse.getStatusCode();
        String reasonPhrase = appResponse.getReasonPhrase();
        Map<String, String> headers = appResponse.getResponseHeaders();
        InputStream data = appResponse.getData();

        return client.createXWalkWebResourceResponse(mimeType, encoding, data, statusCode, reasonPhrase, headers);
    }
}

public final class CrossWebViewClient extends XWalkResourceClient {
    @Override
    public XWalkWebResourceResponse shouldInterceptLoadRequest(XWalkView view, XWalkWebResourceRequest request) {
        AppWebResourceRequest mappedRequest = requestMapper.toGenericRequest(request);
        AppWebResourceResponse interceptedResponse = requestInterceptor.shouldInterceptRequest(mappedRequest);
        if (interceptedResponse == null) {
            return super.shouldInterceptLoadRequest(view, request);
        }
        return responseMapper.toTargetResponse(this, interceptedResponse);
    }
}

感谢使用人行横道。

要创建 XWalkWebResourceResponse，您应该在 XWalkResourceClient 中使用 createXWalkWebResourceResponse，请参阅 here .由于内部 block 问题，无法使用通用构造函数创建。

这是一个关于如何使用它的示例:https://github.com/crosswalk-project/crosswalk/pull/3454/files

 class MyResourceClient extends XWalkResourceClientInternal {
 MyResourceClient(XWalkViewInternal view) {
     super(view);
 }
 @Override
 XWalkWebResourceResponseInternal shouldInterceptLoadRequest(XWalkViewInternal view,
         XWalkWebResourceRequestInternal request) {
     // Handle it here.
     // Use createXWalkWebResourceResponse instead of "new XWalkWebResourceResponse"
     // to create the response.
     // Similar with before, there are two function to use:
     // 1) createXWalkWebResourceResponse(String mimeType, String encoding, InputStream data)
     // 2) createXWalkWebResourceResponse(String mimeType, String encoding, InputStream data,
     //             int statusCode, String reasonPhrase, Map<String, String> responseHeaders)
     ...
 }

稍后您也可以在 XWalkView API 文档中看到这一点。
