Question

我终于让我的应用程序“看似”发布到https。但是，每次发布并获得结果时，结果为-200。这个结果是来自服务器的响应，告诉我需要进行身份验证。如果我正确验证，结果将是积极的。我发帖进行身份验证......所以回复只是告诉我它失败了。我已经和服务器管理员谈过，他说我可能在实际的帖子里有一个空间。

我的问题是，如何查看正在发布的完整邮件？基本上，我如何检查以确保我在Web浏览器中放入URL的内容与应用程序中发布的内容相同？现在，我打印了一些，但我怎么知道所有的消息都是正确的。从“https”一直到消息的最后。

提前致谢!!任何帮助表示赞赏，如果您发现我目前有什么问题，请告诉我！谢谢！

发布时，网址应如下所示：

Answer 1

我从未听说过-200表示需要进行身份验证。这是您的服务器发送的自定义响应代码吗？通常，当您需要进行身份验证时，您将获得401等。

以下是standard HTTP status codes

此外，当您发布参数时，它们不会添加到URL的末尾，因此您的URL看起来与您在问题顶部的内容不同。

它只是https://ipaddress/health_monitoring/admin.php

Answer 2

我刚才注意到的一件事是：

tempMap.put("username", "uName");
tempMap.put("password", "pWord");

您将常量值"uName"和"pWord"放入地图而不是变量。它应该是：

tempMap.put("username", uName);
tempMap.put("password", pWord);

您可能还想首先在params上调用.trim()以确保没有额外的空格。

我弄清楚我的问题是什么！在我将帖子附加到网址之前，我实际上是发布到http ... oops。

下面列出了需要示例的帖子的固定代码。

private static String post(String urlString, Map formParameters)
throws MalformedURLException, ProtocolException, IOException {
    DataOutputStream ostream = null;

    trustAllHosts();
    URL tempUrl;
    StringBuffer buf = new StringBuffer();
    if(formParameters != null) {
        Set parameters = formParameters.keySet();
        Iterator it = parameters.iterator();
        //StringBuffer buf = new StringBuffer();

        for(int i = 0, paramCount = 0; it.hasNext(); i++) {
            String parameterName = (String) it.next();
            String parameterValue = (String) formParameters.get(parameterName);

            if(parameterValue != null) {
                parameterValue = URLEncoder.encode(parameterValue);
                if(paramCount > 0) {
                    buf.append("&");
                }
                buf.append(parameterName);
                buf.append("=");
                buf.append(parameterValue);
                ++paramCount;
            }
        }
        Log.v("smartdbhelper adding post parameters", buf.toString());


    }
    urlString = urlString + "?" + buf;
    Log.v("smartdbhelper url string", urlString);
    tempUrl = new URL(urlString);
    HttpsURLConnection https = (HttpsURLConnection) tempUrl.openConnection();
    https.setHostnameVerifier(DO_NOT_VERIFY);
    Log.v("smartdbhelper adding post parameters", https.toString());
    https.setRequestMethod("POST");
    https.setDoInput(true);
    https.setDoOutput(true);
    ostream = new DataOutputStream(https.getOutputStream());
    ostream.writeBytes(buf.toString());


if( ostream != null ) {
    ostream.flush();
        ostream.close();
    }
    Object contents = https.getContent();
    InputStream is = (InputStream) contents;
    StringBuffer buf2 = new StringBuffer();
    int c;
    while((c = is.read()) != -1) {
        buf2.append((char)c);
        Log.v("smartdbhelper bugger", buf2.toString());
    }
    https.disconnect();
    return buf2.toString();
}

https发布，未收到预期值
