我試圖使用NSURLSession
提出請求。我需要發送包含雙值的數據。我使用NSNumber
在NSDictionary
中存儲雙值。我張貼的數據是這樣的:服務器響應「java.lang.Integer不能轉換爲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];
}
當我打印使用NSLog
PARAMS,它打印出這樣的:
params : {
budget = 1000;
distance = 50;
latitude = "30.73979949951172";
longitude = "76.78269958496094";
pageNo = 0;
rating = 4;
}
服務器就像是返回響應:
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;
}
這個錯誤顯然是顯示服務器是無法種類整數值加倍。由於距離參數,我得到這個錯誤。我將距離作爲double值傳遞,然後服務器如何將其作爲整數值進行查找?
問題是服務器無法識別這些參數。服務器部分正常工作,因爲我已經使用谷歌瀏覽器的Swagger UI發送了一個POST,並且它完美地工作。
