我尝试将NSDictionary转换为
JSON数据,并使用setHTTPBody在“POST”请求中将其发送到
PHP.server.
当我从我的应用程序发送时,我从服务器收到一个空值,但是当我从PostMan发送JSON时,我收到了这些对象.
我哪里错了?
- (void)viewDidLoad
{
[super viewDidLoad];
NSError *error = nil;
NSString *url = [NSString stringWithFormat:@"http://myAddress/sql_service.php"];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:url]];
[request setHTTPMethod:@"POST"];
[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[request setValue:@"application/json" forHTTPHeaderField:@"Accept"];
NSArray *arrayOfStrings = @[@"alex",@"dima"];
NSDictionary *dict = @{@"request_type" : @"select_with_params",
@"table" : @"user",
@"where" : @"f_name=? OR f_name=?",
@"values" : arrayOfStrings};
NSData* jsonData1 = [NSJSONSerialization dataWithJSONObject:dict options:kNilOptions error:&error];
[request setHTTPBody:jsonData1];
NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
[connection start];
}
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
if (data)
{
[receivedData appendData:data];
}
else
{
}
}
- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
{
NSLog(@"didFailWithError");
}
- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
NSError * error = nil;
NSMutableDictionary *dictionary = [NSJSONSerialization JSONObjectWithData:receivedData options:0 error:&error];
NSLog(@"connectionDidFinishLoading");
}
这是我需要发布的json.
{
request_type: "select_with_params",
table: "user",
where: "f_name=? OR f_name=?",
values: ["dima", "alex"]
}
didReceiveData中的数据是:
最佳答案 尝试AFNetworking
编辑
NSString *url = [NSString stringWithFormat:@"http://myAddress/sql_service.php"];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:url]];
[request setHTTPMethod:@"POST"];
[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[request setValue:@"application/json" forHTTPHeaderField:@"Accept"];
NSArray *arrayOfStrings = @[@"alex",@"dima"];
NSDictionary *dict = @{@"request_type" : @"select_with_params",
@"table" : @"user",
@"where" : @"f_name=? OR f_name=?",
@"values" : arrayOfStrings};
NSData* jsonData1 = [NSJSONSerialization dataWithJSONObject:dict options:kNilOptions error:&error];
[request setHTTPBody: [[NSString stringWithFormat:@"%@", jsonData1] dataUsingEncoding:NSUTF8StringEncoding]];
AFHTTPRequestOperation *op = [[AFHTTPRequestOperation alloc] initWithRequest:request];
op.responseSerializer = [AFJSONResponseSerializer serializer];
[op setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject){
if (responseObject)
{
NSLog(@"Success!");
}} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(@"Error");
}];
[op start];
希望这可以帮助
