Question

我正在尝试我的第一个GAE服务器和Android连接。我在我的计算机上通过Android ADT运行GAE服务器（192.168.1.24）。我的Android设备通过USB以开发人员模式连接。我正在尝试从设备发出HTTP请求并存储响应。但我得到以下错误。

从Android设备发起http请求的声明如下。

String alias=UserAuth.doAuth(username, password);

UserAuth.doAuth（）如下所示

 public static String doAuth(String username,String password) {
    // CONSTRUCT GET REQUEST URL
    String url = "192.168.1.24/myserver?username=qwerty&password=qwerty"
    // XML RESPONSE AS A STRING GETS RETURNED
    String response = GetMethods.doGetWithResponse(URL_BASE, httpClient);

    return response;
}

GetMethods.doGetWithResponse（）如下所示

public static String doGetWithResponse(String mUrl,DefaultHttpClient httpClient){
    String ret=null;
    HttpResponse response=null;
    //initiate get method with username and password
    HttpGet getMethod=new HttpGet(mUrl);
    try{
        //use http client to execute method
        response=httpClient.execute(getMethod);
        if(response!=null){
            //convert http response to string
            ret=getResponseBody(response);
        }
    }catch(Exception e){
        e.printStackTrace();
    }
    return ret;
}

请指出解决方案。

Answer 1

异常java.lang.IllegalArgumentException: Illegal character in scheme at index 0: 192.168.1.24:8889/myserver?username=qwerty&password=qwerty似乎表明可以通过尝试以下方法来解决问题：

在您的网址字符串前加上http://，并查看是否有效。
为您的网址字符串添加http://前缀，并正确编码网址。
