从Android应用程序读取HTML源代码 [英] Reading HTML source from android app

问题描述

我想从用户输入时，code我到目前为止是这样的一个网站在一个字符串的HTML源代码：

I'm trying to get the HTML source in a string from a web site that the user enters, the code I have so far looks like this:

public String getURLContent(String url)
{
    try 
    {
        DefaultHttpClient httpClient = new DefaultHttpClient();
        HttpGet httpGet = new HttpGet(url);
        ResponseHandler<String> resHandler = new BasicResponseHandler();
        String page = httpClient.execute(httpGet, resHandler);
        return page;
    }
    catch (ClientProtocolException e)
    {
        e.printStackTrace();
        return "";
    }
    catch (IOException e)
    {
        e.printStackTrace();
        return "";
    }
}

每当我尝试运行此，我打它根据文档的第二个catch（IOException异常），表示服务器未能给予有效回应...我像HTTP网站的测试这样的：\\ www.google .COM \\，所以他们绝对应该响应

Every time I try to run this I hit the second catch (IOException), which according to the documentation means the server failed to give a valid response... I am testing this with sites like "http:\www.google.com\", so they should definitely be responding

推荐答案

您code是好的。请务必粘贴完整的网站路径： HTTP：// WWW。 [页码]。 [域] 例如： http://www.google.com
和此许可添加到的Andr​​oidManifest.xml

Your code is ok. Make sure you paste full website path : http://www. [page] . [domain] eg.: http://www.google.com And add this PERMISSION to AndroidManifest.xml

<uses-permission android:name="android.permission.INTERNET" />

之前（如果是新项目）：

just before (if it is new project):

<application android:label="@string/app_name">

完整的示例：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
          package="com.example"
          android:versionCode="1"
          android:versionName="1.0">
    <uses-sdk android:minSdkVersion="10"/>
    <uses-permission android:name="android.permission.INTERNET" />
    <application android:label="@string/app_name">
        <activity android:name="MyActivity"
                  android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>
                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
        </activity>
    </application>
</manifest>
