我想使用下面的代码将数据传递给POST
JSON Web服务.
NSString *urlString = @"http://3.10.204.99:9090/service/outage/data/getShortFormData";
NSDictionary *inputData = [[NSDictionary alloc] initWithObjectsAndKeys:
@"1020",@"outageId",@"Alex",@"customerName",nil];
NSError *error = nil;
NSData *jsonInputData = [NSJSONSerialization dataWithJSONObject:inputData options:NSJSONWritingPrettyPrinted error:&error];
NSString *jsonInputString = [[NSString alloc] initWithData:jsonInputData encoding:NSUTF8StringEncoding];
[self checkWithServer:urlString jsonString:jsonInputString];
-(void)checkWithServer:(NSString *)urlname jsonString:(NSString *)jsonString{
NSURL *url1 = [NSURL URLWithString:urlname];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url1];
[request setHTTPMethod:@"POST"];
[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[request setValue:@"charset=utf-8" forHTTPHeaderField:@"Content-Type"];
[request setHTTPBody:[jsonString dataUsingEncoding:NSUTF8StringEncoding]];
NSURLResponse *response;
NSError *err;
NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&err];
id jsonResponseData = [NSJSONSerialization JSONObjectWithData:responseData options:kNilOptions error:nil];
NSDictionary *jsonResponseDict;
if ([jsonResponseData isKindOfClass:[NSDictionary class]]) {
jsonResponseDict = jsonResponseData;
} else {
// Error-handling code
}
jsonResponseData = [jsonResponseDict objectForKey:@"d"];
if (jsonResponseData == nil) {
// Server may have returned a response containing an error
// The "ExceptionType" value is returned from my .NET server used in sample
id jsonExceptioTypeData = [jsonResponseDict objectForKey:@"ExceptionType"];
if (jsonExceptioTypeData != nil) {
NSLog(@"%s ERROR : Server returned an exception",__func__);
NSLog(@"%s ERROR : Server error details = %@",__func__,jsonResponseDict);
}
}
}
对此的任何帮助都会感到遗憾.
谢谢你们.
解决方法
请尝试以下代码
+(NSData *)postDataToUrl:(NSString*)urlString:(NSString*)jsonString
{
NSData* responseData = nil;
NSURL *url=[NSURL URLWithString:[urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
responseData = [NSMutableData data] ;
NSMutableURLRequest *request=[NSMutableURLRequest requestWithURL:url];
NSString *bodydata=[NSString stringWithFormat:@"data=%@",jsonString];
[request setHTTPMethod:@"POST"];
NSData *req=[NSData dataWithBytes:[bodydata UTF8String] length:[bodydata length]];
[request setHTTPBody:req];
NSURLResponse* response;
NSError* error = nil;
responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
NSString *responseString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
NSLog(@"the final output is:%@",responseString);
return responseData;
}
