通过POST而不是GET将数据传递到目标c [英] Passing data to objective c with POST rather than GET

问题描述

我一直在使用url拦截方法，通过将数据作为url编码的参数传递并使用NSURLProtocol来拦截数据，从而将数据从javascript传递到目标C，但是我现在想发送更大量的数据，例如说10,000个字符长字符串，但这在GET请求中似乎不切实际.对吧?

I have been using the url intercept method to pass data from javascript to objective C by passing the data as url encoded parameters and using NSURLProtocol to intercept the request however I am now wanting to send larger amounts of data like say 10,000 character long strings but this does not seem practical to do in a GET request. Right?

目标c是否有办法拦截从UIWebView发送的POST数据?
如果是这样，我仍然使用NSURLProtocol以及如何获取POST数据吗?
如果没有其他方法，我可以将大量数据从UIWebView传递到目标c?

Is there a way for objective c to intercept POST data sent from a UIWebView?
If so do I still use NSURLProtocol and how do I get the POST data?
If not is there some other way I can pass larger amounts of data from the UIWebView to objective c?

推荐答案

在使用类似以下代码时:

When using code like:

@implementation AppProtocolHandler

+ (void)registerSpecialProtocol {
    static BOOL inited = NO;

    if (!inited) {
        inited = YES;
        [NSURLProtocol registerClass:[AppProtocolHandler class]];
    }
}

- (void)handleRequest {
    NSURLRequest *request = [self request];

    // null when via app:// but works when via http://
    NSLog(@"[request HTTPBody]: %@", [request HTTPBody]);
}

+ (BOOL)canInitWithRequest:(NSURLRequest *)request {
    return YES;
}

+ (NSURLRequest *)canonicalRequestForRequest:(NSURLRequest *)request {
    return request;
}

@end

对某些协议(例如app://)的请求将导致[request HTTPBody]为null.但是，如果通过http://发送，则[request HTTPBody]将按预期将请求数据保存在NSData对象中.

Requests to some protocols (e.g. app://) will result in [request HTTPBody] being null. But if you send through http:// then the [request HTTPBody] will have the request data in an NSData object as expected.

所以您的Javascript应该类似于:

So your Javascript should look something like:

$.post("http://test/hello/world", {'data':"foo bar"});

并且不类似:

$.post("app://test/hello/world", {'data':"foo bar"});
