后端开发人员在POST请求中给出了这些说明：
>路线：{url} / {app_name / {controller} / {action}
控制器和动作应该是小帽子.
> API测试链接：http：****************
>请求应该使用POST方法.
>参数应通过请求内容体(FormUrlEncodedContent)传递.
>参数应该是json格式.
>参数是关键的.

我传递格式为JSON的字典.他同意我能够传递正确的数据.我可以连接到API,但是当我尝试发送数据进行注册时总是返回“Failed”.没有连接问题,但是我没有传输数据.
这里的Android开发人员使用相同的API没有问题,但是由于他不熟悉iOS,所以无法帮助我.
我失踪了什么
解决方法
尝试这样的代码
目标C
NSString *post =[NSString stringWithFormat:@"AgencyId=1&UserId=1&Type=1&Date=%@&Time=%@&Coords=%@&Image=h32979`7~U@)01123737373773&SeverityLevel=2",strDateLocal,strDateTime,dict]; NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES]; NSString *postLength = [NSString stringWithFormat:@"%d",[postData length]]; NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease]; [request setURL:[NSURL URLWithString:[NSString stringWithFormat:@"http://google/places"]]]; [request setHTTPMethod:@"POST"]; [request setValue:postLength forHTTPHeaderField:@"Content-Length"]; [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"]; [request setHTTPBody:postData]; NSError *error; NSURLResponse *response; NSData *urlData=[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error]; NSString *str=[[NSString alloc]initWithData:urlData encoding:NSUTF8StringEncoding];
Swift 2.2
var post = "AgencyId=1&UserId=1&Type=1&Date=\(strDateLocal)&Time=\(strDateTime)&Coords=\(dict)&Image=h32979`7~U@)01123737373773&SeverityLevel=2"
var postData = post.dataUsingEncoding(NSASCIIStringEncoding,allowLossyConversion: true)!
var postLength = "\(postData.length)"
var request = NSMutableURLRequest()
request.URL = NSURL(string: "http://google/places")!
request.HTTPMethod = "POST"
request.setValue(postLength,forHTTPHeaderField: "Content-Length")
request.setValue("application/x-www-form-urlencoded",forHTTPHeaderField: "Content-Type")
request.HTTPBody = postData
NSError * error
NSURLResponse * response
var urlData = try! NSURLConnection.sendSynchronousRequest(request,returningResponse: response)!
var str = String(data: urlData,encoding: NSUTF8StringEncoding)
Swift 3.0
let jsonData = try? JSONSerialization.data(withJSONObject: kParameters)
let url: URL = URL(string: "Add Your API URL HERE")!
print(url)
var request: URLRequest = URLRequest(url: url)
request.httpMethod = "POST"
request.httpBody = jsonData
request.setValue(Constant.UserDefaults.object(forKey: "Authorization") as! String?,forHTTPHeaderField: "Authorization")
request.setValue(Constant.kAppContentType,forHTTPHeaderField: "Content-Type")
request.setValue(Constant.UserAgentFormat(),forHTTPHeaderField: "User-Agent")
let task = URLSession.shared.dataTask(with: request,completionHandler: { data,response,error in
if data != nil {
do {
let json = try JSONSerialization.jsonObject(with: data!,options: .allowFragments) as! NSDictionary
print(json)
} catch let error as NSError {
print(error)
}
} else {
let emptyDict = NSDictionary()
}
})
task.resume()
我希望这段代码对你有用.
