php - 发布请求未从 iOS 设备到达服务器

尝试向远程 PHP 文件发出简单的发布请求。我没有收到服务器上的参数。我使用 Postman Btw 收到的。所以服务似乎还可以。此处似乎缺少 iOS 代码。

- (void) sendPostRequest {
NSError *error;

NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURLSession *session = [NSURLSession sessionWithConfiguration:configuration delegate:self delegateQueue:nil];
NSURL *url = [NSURL URLWithString:baseURLPost];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request addValue"application/json" forHTTPHeaderField"Content-Type"];
[request addValue"application/json" forHTTPHeaderField"Accept"];

[request setHTTPMethod"OST"];
NSDictionary *mapData = [[NSDictionary alloc] initWithObjectsAndKeys:
                         @"JSON", @"responseType",
                         [UserManager sharedInstance].user.username, @"username",
                            self.textView.text, @"text",
                         nil];

NSData *postData = [NSJSONSerialization dataWithJSONObject:mapData options:0 error:&error];
allowLossyConversion:YES];
[request setHTTPBody:postData];
[[session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
    if (error) {
        NSLog(@"%@", [error.userInfo valueForKey"NSDebugDescription"]);
    } else {
       NSArray *jsonResponseArray = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingAllowFragments error:&error];
        NSLog(@"%@", jsonResponseArray);
    }
}] resume];
}

我的 PHP 代码接收帖子请求。

<?php
header("Content-type:application/json");

$postText= $_POST['text'];
$username = $_POST['username'];
$itemType = $_POST['itemType'];
$responseType = $_POST['responseType'];
$pictureLink = $_POST['pictureLink'];
$timestamp = $_POST['timestamp'];
$tags = $_POST['tags'];

if($timestamp==null){
    $timestamp = date('Y-m-d G:i:s');
}
$arr = array('username' => $username);
echo json_encode($arr);
?>

jsonResponseArray从这是username = "<null>";

Best Answer-推荐答案

使用

$handle = fopen('php://input','r'); 
$jsonInput = fgets($handle); 

代替$_POST

像这样:

<?php
    header("Content-type:application/json");

$handle = fopen('php://input','r');
$jsonInput = fgets($handle);
$arr = json_decode($jsonInput, true);

$postText= $arr['text'];
$username = $arr['username'];
$itemType = $arr['itemType'];
$responseType = $arr['responseType'];
$pictureLink = $arr['pictureLink'];
$timestamp = $arr['timestamp'];
$tags = $arr['tags'];

if($timestamp==null){
    $timestamp = date('Y-m-d G:i:s');
}
$arr = array('username' => $username);
echo json_encode($arr);
?>
