Question

我想在android中使用webview发布数据。试过下面的代码，

String postdata="username=abcd";
myWebView.postUrl(url, EncodingUtils.getBytes(postData, "BASE64"));

但未获得所需的输出。如果有任何其他方式在网页浏览中发布数据，请与我们联系。

在内部监督办公室也是如此，并成功实施。如下所示是IOS中的代码：

NSString *loginUrl = @"https://www.abcdefgh.com/SellOnline/j_spring_check";
    NSURL *url = [NSURL URLWithString:loginUrl];
    NSMutableURLRequest *requestObj = [NSMutableURLRequest requestWithURL:url];

    // POST the username password
    [requestObj setHTTPMethod:@"POST"];
    NSString *postString = [NSString stringWithFormat:@"agent=%@", @"839878"];
    NSData *data = [postString dataUsingEncoding: NSUTF8StringEncoding];
    [requestObj setHTTPBody:data];

    self.webview.delegate = self;
    [self.webview loadRequest:requestObj];\

Load the WebView In FIle


WebView webvHelp = (WebView) findViewById(R.id.webvHelp);
        progressBar = (ProgressBar) findViewById(R.id.progressBar);
        progressBar.getProgressDrawable().setColorFilter(getResources().getColor(R.color.colorAccent), PorterDuff.Mode.SRC_IN);
        webvHelp.getSettings().setBuiltInZoomControls(true);
        webvHelp.getSettings().setDisplayZoomControls(false);
        webvHelp.setWebChromeClient(new WebChromeClient()
        {
            public void onProgressChanged(WebView view, int progress)
            {
                progressBar.setProgress(progress * 100);
            }
        });

        webvHelp.setWebViewClient(new WebViewClient()
        {
            @Override
            public void onPageStarted(WebView view, String url, Bitmap favicon)
            {
                if (!progressBar.isShown()) 
                {
                    progressBar.setVisibility(View.VISIBLE);
                }
                super.onPageStarted(view, url, favicon);
            }

            @Override
            public void onPageFinished(WebView view, String url) {
                if (progressBar.isShown()) {
                    progressBar.setVisibility(View.GONE);
                }
                super.onPageFinished(view, url);
            }

            @Override
            public boolean shouldOverrideUrlLoading(WebView view, String url) 
            {
                view.loadUrl(url);
                return super.shouldOverrideUrlLoading(view, url);
            }
        });
        webvHelp.loadUrl(HELP_URL);
