brew开发浏览器问题

[jun_sun_2008]

为什么调用 IWEBRESP_GetInfo返回一个失败的东西呢？代码如下：


#include "AEEAppGen.h" // Applet helper file
#include "helloworld.bid" // Applet-specific header that contains class ID
#include "nmdef.h"
#include "AEEWeb.h"
#include "AEEHtmlViewer.h"




typedef struct _helloworld {
AEEApplet a ; // First element of this structure must be AEEApplet
AEEDeviceInfo DeviceInfo; // always have access to the hardware device information
AEECallback cbWeb;
WebRespInfo *pRespInfo;
IWebResp *pIWebResp;
IDisplay *pIDisplay; // give a standard way to access the Display interface
IShell *pIShell; // give a standard way to access the Shell interface
IHtmlViewer *pIHtmlView;
// add your own variables here...
IWeb *pIWeb;
char *buffer;
} helloworld;

希望个位高手 指点一下 到底是哪里出了问题

[sunyymq]

.... 你的IP地址不对，你也没有代理！

[kingfenggg]

是不是请求没有发送正确？需要通过错误信息来判读哪里的原因

[zxzyzw]

最近研究这个
我猜大概是你的默认网络链接设置的问题（默认或者是第一个）
不能用ctwap和cmwap，需要用net之类的apn

[wspabout]

这类问题我遇到过的，我以前一直返回失败，你是在模拟器上还是在真机上测试，

[llfshow]

返回的错误值是多少？

[robert0000]

我也有类似的错误：

在网络连接的WebCbk()回调函数中调用pInfo = IWEBRESP_GetInfo(pMe->pWebResp);然后WEB_ERROR_SUCCEEDED(pInfo->nCode)判断错误为：WebResponse Error: -1285。

我查了aeeerror.h后对应的错误提示是：#define WEB_ERROR_UNSUPSCHEME (WEB_ERROR_BASE+5) /* unsupported scheme, no handler found */
在网上搜索unsupported scheme得到：Each handler knows how to open URLs for a particular URL scheme (http, ftp, etc.),
估计和协议有关吧。

因为是在回调函数中调用I接口，好像没办法trace再跟踪了，查看ppp log也没任何网络连接记录，但通过浏览器可打开我们的目标网址。我们想不到其他方法了，各位大侠帮忙啊

[bencharluo]

顶一个

[llfshow]

我也出现过 -1285 的错误。
出现这个的情况是 URL 写的不对，也许是服务器没有打开，或者是参数传错了。
另外，IWEB_GetResponse 的参数设置也会引起这个错误。
这样写试试：
IWEB_GetResponse(pMe->m_pWeb,
(pMe->m_pWeb, &(pMe->m_pWebResp), &(pMe->callback),pMe->m_pUrl,
WEBOPT_CONNECTTIMEOUT, 5000,
WEBOPT_METHOD,"POST",
WEBOPT_END));

[pclogic]

llfshow 说得对, 这个的情况是 URL 写的不对，也许是服务器没有打开，或者是参数传错了

留名关注后续

[strayedbird]

IHTMLViewer 本身具有上网下载内容的功能，不必使用IWEB_GetResponse去下载。
如果使用外网，有一个关键环节是设置ctwap 网关。
