ASIFormDataRequest在模拟器上起作用,但在设备上不起作用? [英] ASIFormDataRequest works on simulator but not on device?
问题描述
我正在使用ASIFormDataRequest发布三个值,分别是url,标题和摘要.它们在模拟器上都可以正常工作,但在设备上不起作用.这是我正在使用的代码:
I am using ASIFormDataRequest to post three values which are a url, a title and a summary. All of them works fine on simulator but its not working on device. Here are the code that I'm using:
- (IBAction)addLinkPressed:(UIButton *)sender {
ASIFormDataRequest *loginRequest = [ASIFormDataRequest requestWithURL:[NSURL URLWithString:@"http://MyWebsite.com/login.php"]];
[loginRequest setRequestMethod:@"POST"];
[loginRequest setPostValue:[[NSUserDefaults standardUserDefaults] objectForKey:@"defaultUsername"] forKey:@"username"];
[loginRequest setPostValue:[[NSUserDefaults standardUserDefaults] objectForKey:@"defaultPassword"] forKey:@"password"];
[loginRequest setUseKeychainPersistence:YES];
[loginRequest setDelegate:self];
[loginRequest setDidFinishSelector:@selector(requestLoginFinished:)];
[loginRequest setDidFailSelector:@selector(requestLoginFailed:)];
[loginRequest startSynchronous];
NSString *strURL = @"http://MyWebsite.com/send_link.php";
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:[NSURL URLWithString:strURL]];
[request setDelegate:self];
[request setPostValue:self.linkField.text forKey:@"url"];
[request setPostValue:self.linkTitleField.text forKey:@"title"];
[request setPostValue:self.linkSummaryField.text forKey:@"summary"];
[request setDidFinishSelector:@selector(requestDone:)];
[request setDidFailSelector:@selector(requestWentWrong:)];
[request startAsynchronous];
}
任何人都可以帮助我!
推荐答案
首先:不再支持ASIRequest.已知在某些情况下有错误,并且错误不会得到修复.
First of all: ASIRequest is not anymore supported. It is known to be buggy in some cases and that bugs won't be fixed.
第二,关于您的问题,我看到可能会发生错误的两个地方(模拟器和设备之间的差异):
Second one, regarding your question, I see two places where error could occur (difference between simulator and device):
-
您确定设备上的
[[NSUserDefaults standardUserDefaults] objectForKey:@"defaultUsername"]
和[[NSUserDefaults standardUserDefaults] objectForKey:@"defaultPassword"]
设置正确吗?
在iOS模拟器上,您无权访问钥匙串,因此此设置( [loginRequest setUseKeychainPersistence:YES];
)也会在设备上引起问题.
On iOS simulator you have not got access to keychain so this setting ([loginRequest setUseKeychainPersistence:YES];
) could cause problems on the device too.
我建议检查 NSUserDefaults
,最好使用另一个框架,即RestKit
I advice to check NSUserDefaults
and better use another one framework, i.e. RestKit
已编辑
使用RestKit的示例:
Example of using RestKit:
[RKClient clientWithBaseURLString:@"http://example.com"];
RKClient *rkclient = [RKClient sharedClient];
RKParams *params = [RKParams paramsWithDictionary:[NSDictionary dictionaryWithObjectsAndKeys:
username, @"username",
password, @"password", nil]];
[rkclient post:@"/profile" params:params delegate:self];
// implement needed delegate methods
