ios – POST请求使用application / x-www-form-urlencoded

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.

在协议中没有经验5,我搜索并结束了我的代码.

-(id)initWithURLString:(NSString *)URLString withHTTPMEthod:(NSString *)method withHTTPBody:(NSDictionary *)body {
 
    _URLString = URLString;
    HTTPMethod = method;
    HTTPBody = body;
 
    //set error message
    errorMessage = @"Can't connect to server at this moment. Try again later";
    errorTitle = @"Connection Error";
 
    return  self;
}
 
 
-(void)fireConnectionRequest {
 
    NSOperationQueue *mainQueue = [[NSOperationQueue alloc] init];
    [mainQueue setMaxConcurrentOperationCount:5];
 
    NSError *error = Nil;
 
    NSURL *url = [NSURL URLWithString:_URLString];
    NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url];
 
    NSData *sendData = [NSJSONSerialization dataWithJSONObject:HTTPBody options:NSJSONWritingPrettyPrinted error:&error];
    [request setHTTPMethod:@"POST"];
 
    [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
    [request setValue:@"application/json" forHTTPHeaderField:@"Accept"];
 
    [request setHTTPBody: sendData];
    [NSURLConnection connectionWithRequest:request delegate:self];
 
    NSString *jsonString = [[NSString alloc]initWithData:sendData encoding:NSUTF8StringEncoding];
 
 
    //fire URL connectiion request
    [NSURLConnection sendAsynchronousRequest:request queue:mainQueue completionHandler:^(NSURLResponse *response,NSData *responseData,NSError *error) {
 
        //get the return message and transform to dictionary
        NSString *data = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
        returnMessage = [NSJSONSerialization JSONObjectWithData: [data dataUsingEncoding:NSUTF8StringEncoding]
                                                        options: NSJSONReadingMutableContainers
                                                          error:&error];
 
 
        //check return message
        if (!error) {
            [delegate returnMessageForTag:self.tag];
 
        }
        else {
            [delegate returnErrorMessageForTag:self.tag];
        }
 
    }];
 
}

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.
