使用浏览器控件的 PostUrlL API

发布于 2024-09-07 15:59:40 字数 2283 浏览 6 评论 0原文

我正在尝试使用浏览器控件POST一些多部分表单数据到我的服务器。

PostUrlL(); 一旦调用方法，KERN-EXEC 3 就会发生混乱。

这是与我在代码中使用的片段类似的片段。

// These LITerals are copied to pointer vars below
_LIT8(K_txt_Boundary, "0xABeR1122EEFFx0");
_LIT8(K_CT_MultipartFormData,"multipart/form-data");

HBufC *url = HBufC::NewL(URL_SIZE);
HBufC8 *contentType = HBufC::NewL(CONTENT_TYPE_SIZE);
HBufC8 *bufPostData = HBufC::NewL(POST_DATA_SIZE);
HBufC8 *boundary = HBufC::NewL(BOUNDARY_SIZE);

// Check allocation was successful 
// and copy required data to allocated space.

TAny *any = NULL;

TRAPD(error, iBrowser->PostUrlL(
                       *url, 
                       *contentType, 
                       *bufPostData, 
                       boundary, 
                       any)
             );

iBrowser，浏览器控件句柄创建如下： 我省略了错误检查，但我确实捕获了放置以下代码片段的函数调用。

iBrowserCapabilties = TBrCtlDefs::ECapabilityDisplayScrollBar 
                                | TBrCtlDefs::ECapabilityLoadHttpFw 
                                | TBrCtlDefs::ECapabilityGraphicalHistory 
                                | TBrCtlDefs::ECapabilityGraphicalPage 
                                | TBrCtlDefs::ECapabilityClientResolveEmbeddedURL 
                                | TBrCtlDefs::ECapabilityCursorNavigation
                                | TBrCtlDefs::ECapabilityClientNotifyURL;

iBrowserObserver = CBrowserObserver::NewL(this);

iBrowser = CreateBrowserControlL(   
                iAppView, 
                aRect,
                iBrowserCapabilties,
                TBrCtlDefs::ECommandIdBase, 
                NULL, // Soft keys
                iBrowserObserver, // Link Resolver
                NULL,
                NULL // Layout change 
        );

iBrowser->SetBrowserSettingL(TBrCtlDefs::ESettingsCookiesEnabled, ETrue);

我已经通过记录其内容来交叉检查是否有任何指针变量为 NULL，它们一切似乎都很好，除了故意的 any 指针。（文档说它是保留供将来使用的，所以我相信 NULL 应该是一个合适的值）。

我还验证了 iBrowser 是浏览器控件的有效实例。 如上所述，我TRAP包含创建浏览器控件的代码的函数

调用PostUrlL(); 失败并出现恐慌 KERN-EXEC 3。

欢迎任何指示、建议或替代方案。

谢谢。

I'm trying to POST some multipart form data to my server using a Browser Control.

The PostUrlL(); Method Panics with KERN-EXEC 3 as soon as it is invoked.

Here's a snippet similar to the one I'm using in my code.

// These LITerals are copied to pointer vars below
_LIT8(K_txt_Boundary, "0xABeR1122EEFFx0");
_LIT8(K_CT_MultipartFormData,"multipart/form-data");

HBufC *url = HBufC::NewL(URL_SIZE);
HBufC8 *contentType = HBufC::NewL(CONTENT_TYPE_SIZE);
HBufC8 *bufPostData = HBufC::NewL(POST_DATA_SIZE);
HBufC8 *boundary = HBufC::NewL(BOUNDARY_SIZE);

// Check allocation was successful 
// and copy required data to allocated space.

TAny *any = NULL;

TRAPD(error, iBrowser->PostUrlL(
                       *url, 
                       *contentType, 
                       *bufPostData, 
                       boundary, 
                       any)
             );

iBrowser, the browser control handle is created as follows:
I'm ommiting error checking, but I do TRAP the function call within which the following snippet is placed.

iBrowserCapabilties = TBrCtlDefs::ECapabilityDisplayScrollBar 
                                | TBrCtlDefs::ECapabilityLoadHttpFw 
                                | TBrCtlDefs::ECapabilityGraphicalHistory 
                                | TBrCtlDefs::ECapabilityGraphicalPage 
                                | TBrCtlDefs::ECapabilityClientResolveEmbeddedURL 
                                | TBrCtlDefs::ECapabilityCursorNavigation
                                | TBrCtlDefs::ECapabilityClientNotifyURL;

iBrowserObserver = CBrowserObserver::NewL(this);

iBrowser = CreateBrowserControlL(   
                iAppView, 
                aRect,
                iBrowserCapabilties,
                TBrCtlDefs::ECommandIdBase, 
                NULL, // Soft keys
                iBrowserObserver, // Link Resolver
                NULL,
                NULL // Layout change 
        );

iBrowser->SetBrowserSettingL(TBrCtlDefs::ESettingsCookiesEnabled, ETrue);

I've cross checked to see if any of the pointer vars are NULL by logging their contents, they all seem to be fine, except for the any pointer which is intentional. (The document says it's reserved for future use, so I believe NULL should be an appropriate value).

I've also verified that iBrowser is a valid instance of a browser control. As mentiond above, I'm TRAPing the function which contains the code to create the browser control

The call PostUrlL(); fails with panic KERN-EXEC 3.

Any pointers, suggestions or alternatives are welcomed.

Thanks.
