使用 Obj C 和 Xcode 进行基本 HTTP 身份验证
我希望有人可以帮助我解决与 Xcode 2.3 应用程序中的基本 HTTP 身份验证相关的问题。
基本上我在我们的服务器上有一个 PHP 页面，当使用某些参数调用时会返回与服务器条件等相关的数据。
我已经设法让一个小型 Xcode 应用程序工作，它从页面读取数据并使用以下命令填充 NSTextView数据。
然而，为了确保这些信息的安全，我在页面上设置了基本的 HTTP 身份验证，但我无法弄清楚如何在 XCode 中提供用户名和密码。
这是我检索页面的代码。
NSURL *url = [NSURL URLWithString:@"http://www.google.com"];
NSString *content = [NSString stringWIthContentsOfUrl:url];
[myTextView setString:content];
关于 xcode 和 obj c，我仍处于非常基本的初学者水平，所以我将非常感激关于我如何进行此操作的简单示例。
谢谢 克里斯
好的，根据我在查看有关此问题的网站时收到的初步评论，这里发生的事情是，我浏览了提供的网页，并努力让代码在我的程序中工作。
现在，当我运行我的程序并单击按钮进行登录时，调试窗口会在这一行弹出，
NSString *authHeader = [@"Basic " stringByAppendingFormat:@"%@",
[NSString stringWithCString:encodedLoginData length:strlen(encodedLoginData)]];
这是在调试日志中，此时
Program loaded.
sharedlibrary apply-load-rules all
Attaching to program: `/Users/kristiaandavies/getWebData/build/Debug/getWebData.app/Contents/MacOS/getWebData', process 982.
Pending breakpoint 1 - ""AppController.m:10" resolved
我单击“继续”尝试进一步操作，然后从调试日志中获取此信息
(gdb) continue
Current language: auto; currently objective-c
Program received signal: "EXC_BAD_ACCESS".
(gdb)
并且程序冻结了？？？
I am hoping someone can help me with a question i have relating to Basic HTTP Authentication in an Xcode 2.3 application.
Basically i have a PHP page that is on our server and when called with certain parameters returns data relating to the servers condition etc.
i have managed to get a small Xcode application working where by it reads the data from the page and populates an NSTextView with the data.
however to make sure this information stays safe i have setup basic HTTP Authentication on the page, but i cannot work out how to provide the username and password in XCode.
here is my code to retrieve the page.
NSURL *url = [NSURL URLWithString:@"http://www.google.com"];
NSString *content = [NSString stringWIthContentsOfUrl:url];
[myTextView setString:content];
i am still at a very basic beginner level regarding xcode and obj c, so nice simple examples of how i go about this would really be appreciated.
Thanks
Kris
ok following on from the intial comment i got about looking at a website regarding this issue here is whats happened, ive had a look through the webpage supplied and have struggled to get code working in my program.
now when i run my program and click the button to-do the login the debug window pops up on this line
NSString *authHeader = [@"Basic " stringByAppendingFormat:@"%@",
[NSString stringWithCString:encodedLoginData length:strlen(encodedLoginData)]];
this is in the debug log at this point
Program loaded.
sharedlibrary apply-load-rules all
Attaching to program: `/Users/kristiaandavies/getWebData/build/Debug/getWebData.app/Contents/MacOS/getWebData', process 982.
Pending breakpoint 1 - ""AppController.m:10" resolved
i click continue to attempt to get it going further and then get this from the debug log
(gdb) continue
Current language: auto; currently objective-c
Program received signal: "EXC_BAD_ACCESS".
(gdb)
