有关我的应用程序需要使用验证码进行验证。我使用这个链接吧： http://vocublablair.nl/webservices/send.php

它返回一个字符串是这样的：/webservices/simple-php-captcha.php?_CAPTCHA&t=0.59145200+1338304461

然后该链接应该叫做，存在：http://vocublablair.nl/webservices/simple-php-captcha.php?_CAPTCHA&t=0.59145200+1338304461

当我把这种具有相同的HttpClient（所以用正确的会话cookie），它提供了以下错误：

  java.lang.IllegalArgumentException：如果在索引94非法字符查询：http://vocublablair.nl/webservices/simple-php-captcha.php?_CAPTCHA&t=0.59145200+ 1338304461
 

解决方案

我解决了这个问题做如下：

先回必须是HTML EN codeD使用：

  Html.fromHtml（字符串）
 

调用正确的网址：

 内容= sb.toString（）; //取出的链接
字符串的myCookie =;
//从其他的呼叫会话cookie。

名单＆LT;饼干＆GT; 。饼干=（（DefaultHttpClient）的HttpClient）.getCookieStore（）的getCookies（）;
对于（曲奇C：饼干）{
如果（c.getName（）。等于（PHPSESSID））{
    的myCookie = c.getName（）+=+ c.getValue（）;
    打破;
   }
   }

网址URL =新的URL（Html.fromHtml（http://vocublablair.nl+内容）的ToString（））;
URLConnection的连接= url.openConnection（）;
connection.setDoInput（真正的）;
connection.setRequestProperty（曲奇，myCookie时）;
connection.connect（）;
位图位= BitmapFactory.de codeStream（新FlushedInputStream（（的InputStream）connection.getContent（）））;
 

我使用的是FlushedInputStream。在这里阅读有关：的http://twigstechtips.blogspot.com/2011/10/android-loading-jpgpng-images-from-url.html

For my application I need to use a captcha for verification. I am using this link for it: http://vocublablair.nl/webservices/send.php

It returns a string something like this: /webservices/simple-php-captcha.php?_CAPTCHA&t=0.59145200+1338304461

Then that link should be called, being: http://vocublablair.nl/webservices/simple-php-captcha.php?_CAPTCHA&t=0.59145200+1338304461

When I call this with the same HttpClient (so with the right session cookie) it gives the following error:

java.lang.IllegalArgumentException: Illegal character in query at index 94: http://vocublablair.nl/webservices/simple-php-captcha.php?_CAPTCHA&t=0.59145200+1338304461

I solved the problem doing the following:

First of all the link I got back had to be HTML encoded using:

Html.fromHtml(String)

Calling the correct URL:

content = sb.toString(); //the fetched link
String myCookie = "";
//get session cookie from other call.

List<Cookie> cookies = ((DefaultHttpClient)httpClient).getCookieStore().getCookies();
for(Cookie c : cookies){
if(c.getName().equals("PHPSESSID")){
    myCookie = c.getName() + "=" + c.getValue();
    break;
   }
   }

URL url = new URL(Html.fromHtml("http://vocublablair.nl" + content).toString());
URLConnection connection = url.openConnection();
connection.setDoInput(true);
connection.setRequestProperty("Cookie", myCookie);
connection.connect();
Bitmap bit = BitmapFactory.decodeStream(new FlushedInputStream((InputStream) connection.getContent()));

I am using a FlushedInputStream. Read about it here: http://twigstechtips.blogspot.com/2011/10/android-loading-jpgpng-images-from-url.html
