可能重复:
如果数据开始加载但不是webViewDidFinishLoad,则不会触发NSMutableURLRequest超时

我正在使用Async HTTP请求并将我的NSMutableURLRequest的超时设置为30秒,我想在此时间内超时请求.

问题:请求没有超时30秒.超时始终需要90秒.任何解决方案.

这是我的连接代码:

NSMutableURLRequest *myRequest = [[NSMutableURLRequest alloc] initWithURL:myURL cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:30];
[myRequest setHTTPMethod:@"POST"];
[myRequest setHTTPBody:myData];

NSURLConnection *myConnection = [[NSURLConnection alloc] initWithRequest:myRequest delegate:self];

我正在实施以下门格:

- (void)connection:(NSURLConnection *)iConnection didReceiveResponse:(NSURLResponse *)iResponse;
- (void)connection:(NSURLConnection *)iConnection didReceiveData:(NSData *)iElementContructionContextData;
- (void)connection:(NSURLConnection *)iConnection didFailWithError:(NSError *)iError;

我有以下代码,它在iOS7中工作正常,但在iOS8中没有.在iOS8中,应用程序总是使用缓存,即使我已设置NSURLRequestReloadIgnoringCacheData:

NSURL *url = [NSURL URLWithString:k_Chapter_URL];
NSMutableURLRequest* request = [[NSMutableURLRequest alloc] initWithURL:url];

NSURLSessionConfiguration *sessionConfig =
[NSURLSessionConfiguration defaultSessionConfiguration];
sessionConfig.requestCachePolicy = NSURLRequestReloadIgnoringCacheData;
NSURLSession *session = [NSURLSession sessionWithConfiguration:sessionConfig];

[[session dataTaskWithRequest:request
            completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {

            }] resume];

有没有人和我有类似的情况？

我正在尝试对YouTube Data API v3进行授权调用,如下所述:https: //developers.google.com/youtube/v3/docs/activities/list

我得到了一切正常,直到我到达需要访问令牌的部分.

我添加了GoogleID登录,它为我提供了具有以下范围的访问令牌:

"https://www.googleapis.com/auth/youtube"
"https://www.googleapis.com/auth/youtube.force-ssl"
"https://www.googleapis.com/auth/youtube.readonly"

这些是三个范围,在谷歌的参考中提到并使用.

    let url = NSURL(string: theURLString)

    let sessionConfig = NSURLSessionConfiguration.defaultSessionConfiguration()
    let sessionQueue = NSOperationQueue.mainQueue()

    let session = NSURLSession(configuration: sessionConfig, delegate: self, delegateQueue: sessionQueue)

    let request = NSMutableURLRequest(URL: url!)
    request.HTTPMethod = "GET"
    request.addValue("application/json", forHTTPHeaderField: "Content-Type")
    request.addValue("application/json", forHTTPHeaderField: "Accept")

    if Settings.sharedInstance.isLoggedIn {
        request.setValue("Bearer \(Settings.sharedInstance.userToken!)", forHTTPHeaderField: "Authorization")
    }

    let task = session.downloadTaskWithRequest(request)

    task.resume()

电话结束后,我得到了以下答案:

{
error =     {
    code = 401;
    errors =         (
                    {
            domain = global;
            location = Authorization; …

我们使用XML/NSMutableURLRequest从我们的网站上提取内容,有时它会通过"卷曲"样式的撇号和引号,而不是'.NSMutableURLRequest似乎讨厌这些并将它们变成奇怪的\ U00e2\U0080\U0099字符串.

有什么我可以做的事情来防止这种情况吗？我正在使用GET方法,所以我应该以某种方式告诉它使用UTF-8？或者,我错过了什么？

UIApplication* app = [UIApplication sharedApplication];
    app.networkActivityIndicatorVisible = YES;

    NSString *urlStr = [NSString stringWithFormat:@"%@",url];
    NSURL *serviceUrl = [NSURL URLWithString:urlStr];
    NSMutableURLRequest *serviceRequest = [NSMutableURLRequest requestWithURL:serviceUrl];
    [serviceRequest setHTTPMethod:@"GET"];

    NSURLResponse *serviceResponse;
    NSError *serviceError;

    app.networkActivityIndicatorVisible = NO;

    return [NSURLConnection sendSynchronousRequest:serviceRequest returningResponse:&serviceResponse error:&serviceError];

我想将用户名和密码发布到服务器.我想将此用户名和密码转换为Base64编码.因此,将为Authorization字段添加此编码字符串.

是否有任何API可用于在iOS中进行Base64编码,或者我们自己编写？

如何将键值对添加到NSMutableURLRequest的主体？我知道我可以使用这样的东西:

NSURL *url = [[NSURL alloc] initWithString:@"http://localhost:8080/upload/"];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url];
[request setHTTPMethod:@"POST"];
NSString *bodyContents = @"fileName=";
[bodyContents stringByAppendingString:fileName];
[bodyContents stringByAppendingString:@"&"];
[bodyContents stringByAppendingString:@"deviceName="];
[bodyContents stringByAppendingString:deviceName];
[bodyContents stringByAppendingString:@"fileContents="];
[bodyContents stringByAppendingString:fileContents];

但这似乎很麻烦,特别是如果我到达我需要在请求中提交大量值的地方.我希望苹果能提供类似[request addBodyField:@"fileName":fileName]或同样有用的方法,但我无法在文档中找到.有没有我遗失或者我只是坚持附加字符串？

我知道这可能有几个问题,但是当我尝试为我的UIWebView设置一个新的"用户代理"时,我遇到了一个问题.这就是我现在正在做的事情:

NSURL *myUrl = [NSURL URLWithString:auxUrl];
    NSMutableURLRequest *myRequest = [NSMutableURLRequest requestWithURL:myUrl];

    NSMutableString *auxUserAgent = [[NSMutableString alloc] initWithString:[myRequest valueForHTTPHeaderField: @"User-Agent"]];
    [auxUserAgent appendString:@"(iOS)"];

    [myRequest setValue:auxUserAgent forHTTPHeaderField:@"User-Agent"];

    NSLog(@"UA : %@",[myRequest valueForHTTPHeaderField: @"User-Agent"]);

我试图将一些文本附加到实际的用户代理,并在XCode控制台中显示新的用户代理值.

2013-12-16 19:03:42.200应用程序[736:60b] UA:Mozilla/5.0(iPhone; CPU iPhone OS 7_0_4,如Mac OS X)AppleWebKit/537.51.1(KHTML,如Gecko)Mobile/11B554a(iOS)

但是,当我运行我的应用程序时,它会显示旧的应用程序.以下是我在UIWebView中显示的网页中显示的用户代理的屏幕截图:

所以..我的问题是:我错过了什么？系统中有什么东西不允许开发人员更改这些数据？

谢谢.

我有一个简单的GET请求,我试图在我的macOS应用程序中运行.但是我一直收到以下错误:

找不到具有指定主机名的服务器.

我试图从中下载JSON数据的URL是:

https://suggestqueries.google.com/complete/search?client=safari&q=mercedes

如果我在浏览器或在线API测试人员网站(例如Hurl.it)中测试它,请求工作正常.然后自动下载JSON文件.

但是,通过我的macOS应用程序运行请求不起作用.这是我的代码:

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"https://suggestqueries.google.com/complete/search?client=safari&q=mercedes"] cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];
[request setHTTPMethod:@"GET"];

NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURLSession *session = [NSURLSession sessionWithConfiguration:configuration delegate:self delegateQueue:nil];

[[session dataTaskWithRequest:request completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) {

    NSLog(@"Data: %@", data);
    NSLog(@"Response: %@", response);
    NSLog(@"Error: %@", error);

}] resume];

这是完整的错误日志:

当我尝试请求此URL时,我无法获取HTML源代码:http://www.google.co.in/search？ q = search

NSURL *url = [NSURL URLWithString:@"http://www.google.co.in/search?q=search"];

NSMutableURLRequest *urlRequest = [NSURLRequest requestWithURL:url];
NSData *data = [NSURLConnection sendSynchronousRequest:urlRequest returningResponse:nil error:nil];
NSLog(@"Webdata : %@", [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]);

数据始终为NULL.

您好，请帮助我如何为以下api准备NSMutableURLRequest

网址：www.XXXXXXXX.com/api.php

登录：

www.XXXXXXXXXXXX.com/api.php?task=login

发布数据 ：-

“ email” =>用户的电子邮件

“ pw” =>用户密码

json响应：成功登录后的会话ID

我正在尝试这样。

NSMutableURLRequest *request;

request=[NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"www.XXXXXXXX.com/api.php?task=login"]];


[request setHTTPMethod:@"POST"];


NSString *postString =@"email=xxxxxxxx@gmail.com&pw=1234";

[request setValue:[NSString
                   stringWithFormat:@"%d", [postString length]] forHTTPHeaderField:@"Content-length"];

[request setHTTPBody:[postString
                      dataUsingEncoding:NSUTF8StringEncoding]];

NSURLConnection *connection=[[NSURLConnection alloc] initWithRequest:request delegate:self];
