我试图使用NSURLSession
提出请求。我需要发送包含双值的数据。我使用NSNumber
在NSDictionary
中存储双值。我张贴的数据是这样的:服务器响应“java.lang.Integer不能转换为java.lang.Double”
-(void)sortJobsWithLat:(float)lat longt:(float)longt distance:(float)distance budget:(NSInteger)budget rating:(NSInteger)rating page:(NSUInteger)page {
NSError *error;
NSURLSessionConfiguration *defaultConfigObject = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURLSession *defaultSession = [NSURLSession sessionWithConfiguration: defaultConfigObject delegate: nil delegateQueue: [NSOperationQueue mainQueue]];
NSURL * url = [NSURL URLWithString:[NSString stringWithFormat:@"%@%@",BaseURLJobs,SearchJobs]];
NSMutableURLRequest * urlRequest = [NSMutableURLRequest requestWithURL:url];
NSLog(@"url : %@", url);
NSDictionary *params=[[NSDictionary alloc]initWithObjectsAndKeys:[NSNumber numberWithDouble:lat] ,@"latitude",[NSNumber numberWithDouble:longt],@"longitude", [NSNumber numberWithDouble:distance],@"distance", [NSString stringWithFormat:@"%ld",(long)budget] ,@"budget", [NSString stringWithFormat:@"%ld",(long)rating],@"rating", [NSString stringWithFormat:@"%ld",page],@"pageNo",nil];
NSData* jsonData = [NSJSONSerialization dataWithJSONObject:params options:kNilOptions error:&error];
NSLog(@"params : %@",params);
[urlRequest addValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[urlRequest addValue:@"application/json" forHTTPHeaderField:@"Accept"];
[urlRequest setHTTPMethod:@"POST"];
[urlRequest setHTTPBody:jsonData];
NSData *postData = [NSJSONSerialization dataWithJSONObject:params options:0 error:&error];
[urlRequest setHTTPBody:postData];
dataTask =[defaultSession dataTaskWithRequest:urlRequest
completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
if(error == nil)
{
NSError *jsonError;
NSDictionary *jsonObject = [NSJSONSerialization JSONObjectWithData:data
options:kNilOptions
error:&jsonError];
NSLog(@"json object : %@",jsonObject);
}
else{
[AppDel showAlertWithMessage:error.localizedDescription andTitle:nil];
}
}];
[dataTask resume];
}
当我打印使用NSLog
PARAMS,它打印出这样的:
params : {
budget = 1000;
distance = 50;
latitude = "30.73979949951172";
longitude = "76.78269958496094";
pageNo = 0;
rating = 4;
}
服务器就像是返回响应:
json object : {
error = "Internal Server Error";
exception = "java.lang.ClassCastException";
message = "java.lang.Integer cannot be cast to java.lang.Double";
path = "/jobs/searchJobs";
status = 500;
timestamp = 1471760398842;
}
这个错误显然是显示服务器是无法种类整数值加倍。由于距离参数,我得到这个错误。我将距离作为double值传递,然后服务器如何将其作为整数值进行查找?
问题是服务器无法识别这些参数。服务器部分正常工作,因为我已经使用谷歌浏览器的Swagger UI发送了一个POST,并且它完美地工作。
