从UIWebView抓取POST数据 [英] Grabbing POST data from UIWebView

问题描述

我想知道是否有可能在UIWebView中按下提交按钮时捕获POST数据并将其保存.我应该使用javascript并添加eventlisteners以便在提交之前获得值吗?如果是这样，我如何才能将数据返回到obj c中的代码?否则，有没有更简单的方法?谢谢

I was wondering if it were possible to grab POST data and save it when a submit button was pressed in a UIWebView. Should I be using javascript and adding eventlisteners so that I can get the values before the submit goes through? If so, how would I be able to get the data back to my code in obj c? Otherwise, is there any easier way? Thanks

推荐答案

您需要实现UIWebViewDelegate.有一个叫做"shouldStartLoadWithRequest"的钩子，iOS会调用它.

You need to implement the UIWebViewDelegate. There is a hook called "shouldStartLoadWithRequest" that gets called by iOS.

下面的伪代码.

@interface MyController<UIWebViewDelegate>
@end

@implementation MyController
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request       navigationType:(UIWebViewNavigationType)navigationType
{
    // do your magic
    NSData *data = request.HTTPBody; // contains the HTTP body as in an HTTP POST request.

    // return YES to continue to load the URL
}
@end
