Iphone AFN网络发布到REST Web服务
简单的背景故事,我们以前的开发人员使用AsitpRequest发出POST请求并从我们的Web服务检索数据。由于未知原因,我们的应用程序的这一部分停止工作。似乎有足够的时间来证明未来,并与AFN合作。RESTWebService在CakePHP框架上运行 简而言之,我没有使用AFNetworking接收请求-响应字符串 我知道Web服务是有效的,因为我能够使用curl成功发布数据并收到正确的响应: curl-d“数据[Model][field0]=field0value和数据[Model][field1]=field1value” 根据之前开发人员的指示,我提出了以下建议Iphone AFN网络发布到REST Web服务,iphone,cakephp,rest,post,afnetworking,Iphone,Cakephp,Rest,Post,Afnetworking,简单的背景故事,我们以前的开发人员使用AsitpRequest发出POST请求并从我们的Web服务检索数据。由于未知原因,我们的应用程序的这一部分停止工作。似乎有足够的时间来证明未来,并与AFN合作。RESTWebService在CakePHP框架上运行 简而言之,我没有使用AFNetworking接收请求-响应字符串 我知道Web服务是有效的,因为我能够使用curl成功发布数据并收到正确的响应: curl-d“数据[Model][field0]=field0value和数据[Model][fi

- (IBAction)loginButtonPressed {
NSURL *url = [NSURL URLWithString:@"https://example.com/api/class/function.plist"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setHTTPMethod:@"POST"];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
[request setValue:[usernameTextField text] forHTTPHeaderField:@"data[User][email]"];
[request setValue:[passwordTextField text] forHTTPHeaderField:@"data[User][password]"];
AFHTTPRequestOperation *operation = [[[AFHTTPRequestOperation alloc] initWithRequest:request] autorelease];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(@"operation hasAcceptableStatusCode: %d", [operation.response statusCode]);
NSLog(@"response string: %@ ", operation.responseString);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(@"error: %@", operation.responseString);
}];
[operation start];
}
输出:
操作hasAcceptableStatusCode:200
响应字符串:一个空白的plist文件
尝试的解决方案1:
建议的解决方案使用名为operationWithRequest的AFHTTPRequestOperation函数。然而,当我尝试使用上述解决方案时,我得到一个警告“Class method”+operationWithRequest:completion:“not found”(返回类型默认为“id”)
尝试的解决方案2:NSURLConnection。输出:我可以打印发送的成功日志消息,但不能打印响应字符串。
*update-返回空白plist
NSMutableURLRequest *req = [NSMutableURLRequest requestWithURL:url];
NSString *httpBodyData = @"data[User][email]=username@example.com&data[User][password]=awesomepassword";
[httpBodyData dataUsingEncoding:NSUTF8StringEncoding];
[req setHTTPMethod:@"POST"];
[req setHTTPBody:[NSData dataWithContentsOfFile:httpBodyData]];
NSHTTPURLResponse __autoreleasing *response;
NSError __autoreleasing *error;
[NSURLConnection sendSynchronousRequest:req returningResponse:&response error:&error];
// *update - returns blank plist
NSData *responseData = [NSURLConnection sendSynchronousRequest:req returningResponse:nil error:nil];
NSString *str = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
NSLog(@"responseData %@",str);
if (error == nil && response.statusCode == 200) {
// Process response
NSLog(@"success");//returns success code of 200 but blank
NSLog(@"resp %@", response );
} else {
// Process error
NSLog(@"error");
}
使用
AFHTTPClient-postPath:parameters:success:failure:
,传递参数(嵌套字典/数组可以)。如果希望返回plist,请确保让客户端注册afpropertylisterequestoperation
在任何情况下,setValue:forHTTPHeaderField:
不是您想要的。用于指定有关请求本身的信息;数据是请求正文的一部分。AFHTTPClient
自动将参数转换为GET
请求的查询字符串或POST
等的HTTP正文。ese是基本的(去掉我为自己使用而设置的条件)行,最终满足了我对web服务的请求。感谢@8vius和@mattt的建议

您好,Pouria,您是否尝试使用NSURLConnection发送同步请求?尝试的解决方案2:我是如何尝试NSURLConnection的。您是否正确设置了服务器端的所有内容?例如扩展解析、响应布局和它们的视图?这似乎更像是服务器问题,而不是客户端问题。我最终解决了这个问题。我很抱歉我现在正在工作,稍后将发布更新。我解决了此问题,但我感觉我仍然在做一些错误或效率低下的事情。如果您能快速查看我的解决方案,我将不胜感激。谢谢!注册plist操作只会影响使用
AFHTTPClient-HTTPRequestOperationWithRequest:suc创建的请求操作访问:失败:
alloc init
-ingAFHTTPRequestOperation
总是会给你一个AFHTTPRequestOperation
@pouria,这里的路径是什么。它像同一个URL吗。请帮助我,我被路径卡住了。@G.Ganesh我开始有点晚了。路径只是响应HTTP POS的类的一个方法Ts与给定的参数集。我希望您解决了您的问题。
