嗯,这是故事:
我有一些数据需要发送到服务器,但它们应该首先变成JSON dataType。
我做了这样的ajax电话:
$.ajax({
url: url, // the url I want to post to.
type: 'POST',
contenttype:'application/json; charset=utf-8',
beforeSend: //some HTTP basic auth stuff
data: {
name:'test',
key:'foo',
key2:'bar'
},
dataType:'JSON'
});
基本上我期待我发送给服务器的数据是:
[name:test,key:foo,key2:bar]
但我得到的是:
name=test&key=foo&key2=bar
我错过了什么?如何将这些数据转换为JSON?

var data = {'bob':'foo','paul':'dog'};
$.ajax({
url: url,
type: 'POST',
contentType:'application/json',
data: JSON.stringify(data),
dataType:'json'
});

如果您需要执行某些操作,上面的内容对服务器的响应没有任何作用,那么当服务器响应时将调用回调。
var data = {'bob':'foo','paul':'dog'};
$.ajax({
url: url,
type: 'POST',
contentType:'application/json',
data: JSON.stringify(data),
dataType:'json',
success: function(data){
//On ajax success do this
alert(data);
},
error: function(xhr, ajaxOptions, thrownError) {
//On error do this
if (xhr.status == 200) {
alert(ajaxOptions);
}
else {
alert(xhr.status);
alert(thrownError);
}
}
});

我遇到了同样的问题。您不能将对象作为“数据”发送,您需要对对象进行字符串化。请尝试使用对象进行字符串化处理:
$.ajax({
url: url,
type: 'POST',
contentType:'application/json',
data: '{
name:"test",
key:"foo",
key2:"bar"
}',
dataType:'json'
});

试试这个:http://www.abeautifulsite.net/blog/2008/05/postjson-for-jquery/
它短得多:
$.post(url, data, function(response) {
// Do something with the response
}, 'json');

此外,必要时可以创建参数并使用JSON.stringify
指定值....
data: "jsonString="+JSON.stringify(data),
...

我同意数据必须转换为JSON字符串,不仅要与admin
和dataType
设置一致,更重要的是要满足服务器要求。
contentType

有很多方法可以将JSON数据发送到服务器
var data = <?php echo json_encode($data) ?>;
var url = '<?php echo $url ?>';
jQuery.ajax({
type: "POST",
url: url,
data: JSON.stringify(data),
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function(data){
var jsonObj = jQuery.parseJSON(data);
alert(jsonObj.encPassword);
},
failure: function(errorMsg) {
alert(errorMsg);
}
});
<?php
$content = json_encode($data);
$curl = curl_init($url);
curl_setopt($curl, CURLOPT_HEADER, false);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_HTTPHEADER,
array("Content-type: application/json"));
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, $content);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false); //curl error SSL certificate problem, verify that the CA cert is OK
$result = curl_exec($curl);
$response = json_decode($result);
var_dump($response);
curl_close($curl);
?>
<?php
$options = array(
'http' => array(
'method' => 'POST',
'content' => json_encode( $data ),
'header'=> "Content-Type: application/json\r\n" .
"Accept: application/json\r\n"
)
);
$context = stream_context_create($options);
$result = file_get_contents($url, false, $context);
$response = json_decode($result);
var_dump($response);
使用Zend Framework的HTTP客户端:http://framework.zend.com/manual/en/zend.http.client.advanced.html#zend.http.client.raw_post_data
$json = json_encode($data);
$client = new Zend_Http_Client($url);
$client->setRawData($json, 'application/json')->request('POST');
var_dump($client->request()->getBody());
