如何在使用UIWebView自動填充數據時使用RegsEx查找登錄表單?在UIWebView中打開的HTML頁面中自動填充用戶名和密碼
我用下面的代碼來獲取所有表單數據:
int NoOfForms = [[self.browser stringByEvaluatingJavaScriptFromString:@"document.forms.length"] intValue];
NSMutableArray *formData = [[NSMutableArray alloc] initWithCapacity:0];
for (int i = 0 ; i < NoOfForms ; i++)
{
// total number of elements in each form
int elementsInForm = [[self.browser stringByEvaluatingJavaScriptFromString:[NSString stringWithFormat:@"document.forms[%d].elements.length",i]] intValue];
for (int j = 0; j < elementsInForm; j++)
{
// element id of each element
NSString *elementID = [NSString stringWithFormat:@"document.forms[%d].elements[%d].id",i,j];
// element value of each element
NSString *elementValue = [NSString stringWithFormat:@"document.forms[%d].elements[%d].value",i,j];
// dictionary for all values of each element
NSDictionary *elementData = [NSDictionary dictionaryWithObjectsAndKeys:
[NSNumber numberWithInt:i],@"form No",
[NSNumber numberWithInt:j],@"element No",
[self.browser stringByEvaluatingJavaScriptFromString:elementID],@"elementID",
[self.browser stringByEvaluatingJavaScriptFromString:elementValue],@"elementValue",nil];
// add each element data to a mutable array.
[formData addObject:elementData];
}
}
,並具有以下代碼來將數據返回到各自的領域:
for (int i = 0 ; i < [dataArray count]; i++)
{
NSDictionary *elementDict = [dataArray objectAtIndex:i];
int formNumber = [[elementDict objectForKey:@"form No"] intValue];
int elementNumber = [[elementDict objectForKey:@"element No"] intValue];
NSString *formElementID = [elementDict objectForKey:@"elementID"];
NSString *formElementValue = [elementDict objectForKey:@"elementValue"];
if ([[self.browser stringByEvaluatingJavaScriptFromString:[NSString stringWithFormat:@"document.forms[%d].elements[%d].id",formNumber,elementNumber]] isEqualToString:formElementID])
{
[self.browser stringByEvaluatingJavaScriptFromString:[NSString stringWithFormat:@"document.forms[%d].elements[%d].value='%@'",formNumber,elementNumber,formElementValue]];
}
}
現在我只想提交登錄形式..如何找到它?
我遇到了另一個問題:當我的代碼將密碼放入其字段時,一些網站(如mail.google.com)確實會讓這種情況發生,即清空密碼字段。如何解決這個問題呢 ?
更新:目前我已經能夠在mail.google.com上登錄,但無法在belleandclive.com上完成相同的操作。本網站是否爲其登錄表單實施任何安全措施?
