如何使用 jQuery 的 getJSON() 方法传递请求标头?

发布于 2024-09-10 05:13:02 字数 2002 浏览 5 评论 0原文

我需要执行 getJSON() 请求,但如何传递授权和自定义标头?

我遇到的问题是请求标头采用的是名称,而不是值。 URL 通过 fiddler 中的手动请求显示,并作为选项而不是 GET/Url 插入。

这是我们正在尝试做的一个例子,它在 fiddler 中运行良好;我怎样才能用 AJAX 功能复制这个?

GET /Service.svc/logins/gdd53535342/houses/vxcbdfsdg/people/dsgsdggd?format=json HTTP/1.1
User-Agent: Fiddler
Authorization: Basic rgbg423535fa23y4436
X-PartnerKey: df3fgeg-g5g6-b55b-f3d2-dsgg353523
Host: 154.34.53.54:2757

JavaScript 代码:

xhr = new XMLHttpRequest();

$(document).ready(function() {
  $.ajax({
    url: 'http://localhost:437/service.svc/logins/jeffrey/house/fas6347/devices?format=json',
    type: 'GET',
    datatype: 'json',
    success: function() { alert("Success"); },
    error: function() { alert('Failed!'); },
    beforeSend: setHeader       
  });   
});

function setHeader(xhr) {
  xhr.setRequestHeader('Authorization', 'Basic faskd52352rwfsdfs');
  xhr.setRequestHeader('X-PartnerKey', '3252352-sdgds-sdgd-dsgs-sgs332fs3f');
}

Fiddler 正常请求标头:

GET /service.svc/logins/jeffrey/house/fas6347/devices?format=json HTTP/1.1
User-Agent: Fiddler
Authorization: Basic faskd52352rwfsdfs
X-PartnerKey: 3252352-sdgds-sdgd-dsgs-sgs332fs3f
Host: localhost:437

Fiddler 通过 Ajax() 请求标头:

OPTIONS service.svc/logins/jeffrey/house/fas6347/devices?format=json HTTP/1.1
Host: localhost:437
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.6) Gecko/20100625 Firefox/3.6.6
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en-us,en;q=0.5
Accept-Encoding: gzip,deflate
Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7
Keep-Alive: 115
Proxy-Connection: keep-alive
Origin: http://ipv4.fiddler:61975
Access-Control-Request-Method: GET
Access-Control-Request-Headers: authorization,x-partnerkey

I need to do a getJSON() request, but how do I pass authorisation and custom headers?

I am getting issues that the request header is taking the name, but NOT the values. The URL is being shown through a manual request in fiddler to being inserted in as options instead of GET/Url.

Here is an example of what we are trying to do that works fine in fiddler; how can I replicate this with the AJAX function?

GET /Service.svc/logins/gdd53535342/houses/vxcbdfsdg/people/dsgsdggd?format=json HTTP/1.1
User-Agent: Fiddler
Authorization: Basic rgbg423535fa23y4436
X-PartnerKey: df3fgeg-g5g6-b55b-f3d2-dsgg353523
Host: 154.34.53.54:2757

JavaScript code:

xhr = new XMLHttpRequest();

$(document).ready(function() {
  $.ajax({
    url: 'http://localhost:437/service.svc/logins/jeffrey/house/fas6347/devices?format=json',
    type: 'GET',
    datatype: 'json',
    success: function() { alert("Success"); },
    error: function() { alert('Failed!'); },
    beforeSend: setHeader       
  });   
});

function setHeader(xhr) {
  xhr.setRequestHeader('Authorization', 'Basic faskd52352rwfsdfs');
  xhr.setRequestHeader('X-PartnerKey', '3252352-sdgds-sdgd-dsgs-sgs332fs3f');
}

Fiddler Normal Request Headers:

GET /service.svc/logins/jeffrey/house/fas6347/devices?format=json HTTP/1.1
User-Agent: Fiddler
Authorization: Basic faskd52352rwfsdfs
X-PartnerKey: 3252352-sdgds-sdgd-dsgs-sgs332fs3f
Host: localhost:437

Fiddler Through Ajax() Request Headers:

OPTIONS service.svc/logins/jeffrey/house/fas6347/devices?format=json HTTP/1.1
Host: localhost:437

我同意 sunetos 的观点,您必须使用 $.ajax 函数才能传递请求标头。为此,您必须为 beforeSend 事件处理程序编写一个函数,它是 $.ajax() 选项之一。以下是有关如何执行此操作的快速示例:

<html>
  <head>
    <script src="http://code.jquery.com/jquery-1.4.2.min.js"></script>
    <script type="text/javascript">
      $(document).ready(function() {
        $.ajax({
          url: 'service.svc/Request',
          type: 'GET',
          dataType: 'json',
          success: function() { alert('hello!'); },
          error: function() { alert('boo!'); },
          beforeSend: setHeader
        });
      });

      function setHeader(xhr) {
        xhr.setRequestHeader('securityCode', 'Foo');
        xhr.setRequestHeader('passkey', 'Bar');
      }
    </script>
  </head>
  <body>
    <h1>Some Text</h1>
  </body>
</html>

如果运行上面的代码并在 Fiddler 等工具中观察流量,您将看到传入的两个请求标头:

  • securityCode ,其值为 Foo
  • passkey ,其值为 Bar

setHeader函数也可以内联在 $.ajax 选项中,但我想将其调用出来。

希望这有帮助!

I agree with sunetos that you'll have to use the $.ajax function in order to pass request headers. In order to do that, you'll have to write a function for the beforeSend event handler, which is one of the $.ajax() options. Here's a quick sample on how to do that:

<html>
  <head>
    <script src="http://code.jquery.com/jquery-1.4.2.min.js"></script>
    <script type="text/javascript">
      $(document).ready(function() {
        $.ajax({
          url: 'service.svc/Request',
          type: 'GET',
          dataType: 'json',
          success: function() { alert('hello!'); },
          error: function() { alert('boo!'); },
          beforeSend: setHeader
        });
      });

      function setHeader(xhr) {
        xhr.setRequestHeader('securityCode', 'Foo');
        xhr.setRequestHeader('passkey', 'Bar');
      }
    </script>
  </head>
  <body>
    <h1>Some Text</h1>
  </body>
</html>

If you run the code above and watch the traffic in a tool like Fiddler, you'll see two requests headers passed in:

  • securityCode with a value of Foo
  • passkey with a value of Bar

The setHeader function could also be inline in the $.ajax options, but I wanted to call it out.

Hope this helps!

我认为您可以设置标头并仍然使用 getJSON() ,如下所示:

$.ajaxSetup({
  headers : {
    'Authorization' : 'Basic faskd52352rwfsdfs',
    'X-PartnerKey' : '3252352-sdgds-sdgd-dsgs-sgs332fs3f'
  }
});
$.getJSON('http://localhost:437/service.svc/logins/jeffrey/house/fas6347/devices?format=json', function(json) { alert("Success"); }); 

I think you could set the headers and still use getJSON() like this:

$.ajaxSetup({
  headers : {
    'Authorization' : 'Basic faskd52352rwfsdfs',
    'X-PartnerKey' : '3252352-sdgds-sdgd-dsgs-sgs332fs3f'
  }
});
$.getJSON('http://localhost:437/service.svc/logins/jeffrey/house/fas6347/devices?format=json', function(json) { alert("Success"); });

$.getJSON() 方法是简写方法,不允许您指定此类高级选项。为此,您需要使用完整的 $.ajax() 方法。

请注意文档 http://api.jquery.com/jQuery.getJSON/ :

这是一个简写的 Ajax 函数,相当于:

$.ajax({
  url: url,
  dataType: 'json',
  data: data,
  success: callback
});

因此只需使用 $.ajax() 并提供您需要的所有额外参数。

The $.getJSON() method is shorthand that does not let you specify advanced options like that. To do that, you need to use the full $.ajax() method.

Notice in the documentation at http://api.jquery.com/jQuery.getJSON/:

This is a shorthand Ajax function, which is equivalent to:

$.ajax({
  url: url,
  dataType: 'json',
  data: data,
  success: callback
});

So just use $.ajax() and provide all the extra parameters you need.
