我正试图找到一种方法，将字符串和json数据文件传递给在线Php文件，该文件将使用字符串作为表名在MySQL数据库中创建一个表，并将json数据放入该表中。到目前为止，我在iOS端有以下代码：
NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURLSession *urlSession = [NSURLSession sessionWithConfiguration:configuration delegate:self delegateQueue:nil];
NSURL *url = [NSURL URLWithString:@"http://myWebAddress/uploadData.php"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setHTTPMethod:@"POST"];
[request setValue:@"application/json; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
[request setHTTPBody:self.myData];
NSURLSessionDataTask *sessionDataTask = [urlSession dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
if (error) {
NSLog(@"%@", error);
} else {
self.textLabel.text=@"Data uploaded to database!";
}
}];
[sessionDataTask resume];
在网络方面，我有以下Php代码：
<?php
$json_data=file_get_contents('php://input', true);
$post_data = json_decode($json_data);
$dbc=mysql_connect("mysql", "userName", "password");
mysql_select_db("myDatabase");
foreach($post_data as $lineData)
{$lastName=$lineData->lastName;
$firstName=$lineData->firstName;
$company=$lineData->company;
mysql_query("INSERT INTO `peopleDataTable` (`lastName`, `firstName`, `company`) VALUES ('$lastName', '$firstName', '$company')");}
mysql_close($dbc);
if (is_array($post_data))
$response = array("status" => "ok", "code" => 0, "original request" => $post_data);
else
$response = array("status" => "error", "code" => -1, "original_request" => $post_data);
$processed = json_encode($response);
echo $processed;
?>
你能帮我找到一个修改这些代码的解决方案吗？这样我就可以向Php发送一个字符串，并使用该字符串指定表名"peopleDataTable"？
或者我应该完全修改代码？
非常感谢！

请查看下面的链接以将数据作为参数传递，否则您可以使用AFNetwork进行数据传输，它有非常简单的方法。
http://hayageek.com/ios-nsurlsession-example/
-(void)requestFunction:(NSString *)main_url :(NSMutableDictionary *)parameters :(BOOL)post
{
__block NSString *response_string;
__block NSData *objectData;
__block NSMutableDictionary *json;
NSURL *baseURL=[NSURL URLWithString:BASE_URL];
manager = [[AFHTTPSessionManager alloc] initWithBaseURL:baseURL];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
if (post == NO)
{
[manager GET:main_url parameters:parameters success:^(NSURLSessionDataTask *task, id responseObject)
{
response_string=[[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
objectData = [response_string dataUsingEncoding:NSUTF8StringEncoding];
NSError *jsonError;
json = [NSJSONSerialization JSONObjectWithData:objectData
options:NSJSONReadingMutableContainers
error:&jsonError];
[[self delegate] apiResponse:json];
} failure:^(NSURLSessionDataTask *task, NSError *error)
{
STOP_LOAD;
NSLog(@"%@",error);
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Server Error, Please try again later"
message:[error localizedDescription]
delegate:nil
cancelButtonTitle:@"Ok"
otherButtonTitles:nil];
[alertView show];
}];
}
else
{
[manager POST:main_url parameters:parameters success:^(NSURLSessionDataTask *task, id responseObject)
{
response_string=[[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
objectData = [response_string dataUsingEncoding:NSUTF8StringEncoding];
NSError *jsonError;
json = [NSJSONSerialization JSONObjectWithData:objectData
options:NSJSONReadingMutableContainers
error:&jsonError];
// [self requestComplete:json];
[[self delegate] apiResponse:json];
}
failure:^(NSURLSessionDataTask *task, NSError *error) {
NSLog(@"%@",error);
STOP_LOAD;
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Server Error,Please try again later"
message:[error localizedDescription]
delegate:nil
cancelButtonTitle:@"Ok"
otherButtonTitles:nil];
[alertView show];
}];
}
}
你可以看到我的代码，我只是像下面这样调用这个方法，
-(void)Login: (NSString *) User_fb_id
{
NSMutableDictionary *api_call_parameter=[[NSMutableDictionary alloc] init];
[api_call_parameter setObject:User_fb_id forKey:@"user_fb_id"];
[api_call_parameter setObject:@"ios" forKey:@"device_type"];
[api_call_parameter setObject:Device_Token forKey:@"device_id"];
[self requestFunction:LOGIN :api_call_parameter :YES];
}
因此，您可以将数据作为参数通过该字典进行传递。
