从iOS到php脚本的json数据

How can I access json data within a php-script, which it received via http-post? I'm doing the following on the iOS-side:

如何在一个php脚本中访问json数据?我在ios方面做以下事情:

NSData *data = [NSJSONSerialization dataWithJSONObject:object options:0 error:NULL];

NSMutableURLRequest *req = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"http://example.com/script.php"]];
[req setHTTPMethod:@"POST"];
[req setHTTPBody:data];

[NSURLConnection sendSynchronousRequest:req returningResponse:&response error:&err];

How do I access this data in the php-script? In other words, when I call json_decode(...) in the php-script, what is ...?

如何在php脚本中访问这些数据?换句话说，当我在php脚本中调用json_decode(…)时，什么是…?

If your are sending your JSON in POST method , It can be received in PHP with the below code

如果您正在用POST方法发送JSON，可以用PHP接收，代码如下

<?php $handle = fopen('php://input','r');
                $jsonInput = fgets($handle);
                // Decoding JSON into an Array
                $decoded = json_decode($jsonInput,true);
?>

The post request when sent using iOS does not works with $_POST. If similar request is issued using js the json in post does works.

使用iOS发送的post请求不能使用$_POST。如果使用js发出类似的请求，则post中的json有效。

#3

In the php script you take the POST data and do

在php脚本中，您获取POST数据并执行。

json_decode($data);

and that will give you an object you can work with.

这会给你一个你可以使用的对象。

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
    [request setHTTPMethod:@"POST"];
    [request setHTTPBody: jsonData];
    [request setValue:@"text/html" forHTTPHeaderField:@"Content-Type"];
    [request setValue:[NSString stringWithFormat:@"%d", [jsonData length]] forHTTPHeaderField:@"Content-Length"];

This code can be used to send a response
