Question

挣扎着想出这个。看到很多例子，不知道我在这里做错了什么。需要一些新鲜的眼睛。我有一个数组和一个字典，我试图通过HTTPBody发送，然后返回任何一个，只是为了看到它的工作。这就是我所拥有的：

NSURL *url = [NSURL URLWithString:@"http://..."];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setHTTPMethod:@"POST"];
[request setValue:@"application/x-www-form-urlencoded; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
NSString *postData = [NSString stringWithFormat:@"dictofcorners=%@&arrayofids=%@", dict, _idKeys];
NSString *length = [NSString stringWithFormat:@"%d", postData.length];
[request setValue:length forHTTPHeaderField:@"Content-Length"];
[request setHTTPBody:[postData dataUsingEncoding:NSASCIIStringEncoding]];
[NSURLConnection sendAsynchronousRequest:request queue:[NSOperationQueue mainQueue] completionHandler:^(NSURLResponse *response, NSData *data, NSError *error){
    NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse*)response;
    if ([httpResponse statusCode] == 200) {
        NSLog(@"%@", [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:nil]);
    }
}];

服务器端我只想发送回数组或字典。响应为200，数据为空。我如何处理数据服务器端？或者在发送请求之前，我应该做些什么来序列化数组和字典？

<?php
    $dictofcorners = json_decode($_REQUEST['dictofcorners']);
    echo json_encode($dictofcorners);
    //$arrayofids = json_decode($_REQUEST['arrayofids']);
    //echo json_encode($arrayofids);
?>

以下答案！

我是如何让它工作的......显然：

NSMutableDictionary *paramDic = [NSMutableDictionary new];
[paramDic setValue:dic forKeyPath:@"dic"];
[paramDic setValue:_idKeys forKeyPath:@"array"];
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:paramDic options:NSJSONWritingPrettyPrinted error:nil];

NSURL *url = [NSURL URLWithString:@"http://....php"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setHTTPMethod:@"POST"];
[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
NSString *length = [NSString stringWithFormat:@"%d", jsonData.length];
[request setValue:length forHTTPHeaderField:@"Content-Length"];
[request setValue:@"json" forHTTPHeaderField:@"Data-Type"];
[request setHTTPBody:jsonData];
[NSURLConnection sendAsynchronousRequest:request queue:[NSOperationQueue mainQueue] completionHandler:^(NSURLResponse *response, NSData *data, NSError *error){
    NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse*)response;
    if ([httpResponse statusCode] == 200) {
//...

php部分：

$input = file_get_contents("php://input");
$obj = json_decode($input, true);
$dic = $obj['dic'];
$array = $obj['array'];

我不懂php部分，但它有效。基本上只需要创建一个对象来传递身体......所以我创建了一个字典并添加了我需要传递的所有内容。如果有人想解释php部分，php：//输入部分，我很乐意听到它！

HTTPBody中的NSMutableRequest数组和字典，服务器响应
