iphone - ASIHTTPRequest 问题

Question

我知道 ASIHTTPRequest 项目已被 Ben 放弃，但无论如何，现在切换到其他项目已经太晚了，所以我决定尝试处理我遇到的问题。

我正在发布和使用 https 协议(protocol)的请求。 我已应要求禁用持久性连接。

    ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
    [request setUseKeychainPersistence:YES];
    [request setShouldAttemptPersistentConnection:YES];

    // Set the request timeout 
    [request setTimeOutSeconds:REQUEST_TIME_OUT];


    // Upload an image
    NSData *imageData = UIImagePNGRepresentation(imageContainer.mImage);
    [request setPostBody:[NSMutableData dataWithData:imageData]];;

    [request setDelegate:self];
    [request setDidFinishSelector:@selector(uploadRequestFinished:)];
    [request setDidFailSelector:@selector(uploadRequestFailed:)];
    [request startAsynchronous];

我得到的所有信息都是 A connection failure occurred with the kCFErrorDomainCFNetwork error -1005。

我已经在 ASIHTTPRequest 项目的配置中启用了所有 DEBUG 信息，并获得了以下日志

[STATUS] Starting asynchronous request <ASIFormDataRequest: 0x1029e000>

知道为什么会发生崩溃吗？以及如何解决这个问题？

Answer 1

几个月前我遇到了同样的问题。无法保证 Internet 连接，您会发现此错误在 3G 连接上更常见。我的解决方案是提高重试次数。在 ASIHTTPRequest.m 中将重试次数至少修改为 5，看看是否有帮助。

- (BOOL)retryUsingNewConnection
{
    if ([self retryCount] < 5) {

之所以可行，是因为在 -handleStreamError 中捕获了错误 -1005，然后在上述代码中允许多次重试连接。
