问题描述

因此，我有一个JSON数组，我想将其发布到文件中，然后接收响应.但是它似乎不起作用，所以我希望你们能帮我一点忙.

So, I have a JSON array that I want to POST to a file and then receive a response. But somehow it doesn't seem to work, so I was hoping you guys could help me a bit out.

data = JSON.stringify({
        "jsonrpc": "2.0",
        "method": "login",
        "id": 1,
        "params": {
          "params": {
            "username": "1234",
            "password":  "4321"
          }
        }
      });

$.ajax({
        url:"functions/proxy.php",
        type:"POST",
        data : data,
        success: function(data){/* do something*/ },
        error: function(data) {/* do something*/)}
      });

当我提交表单时，error function运行，当var_dumping $_POST时我得到此:

When I submit the form, the error function runs, and I get this when var_dumping $_POST:

array(0) {
}

奇怪的是，当data看起来像这样:

Weird thing is, when data looks like this:

data: "username=1234&password&4321"

我明白了:

Array
(
    [username] => 1291
    [password] => 1877
)

有人可以帮助我如何以JSON格式发送数据吗?

Could anyone help me with how I can be able to send the data in JSON format?

推荐答案

$.ajax({
        url:"functions/proxy.php",
        type:"POST",
        data : data,
        success: function(data){/* do something*/ },
        error: function(data) {/* do something*/)}
      });

应该是

$.ajax({
        url:"functions/proxy.php",
        type:"POST",
        data : {mydata:data},
        success: function(data){/* do something*/ },
        error: function(data) {/* do something*/)}
      });

尝试

print_r($_POST);
