Question

我遇到了一个非常奇怪的问题，我想在我的ajax请求中向服务发送一个额外的参数授权，就像这样

Request headers
Authorization: bearer t-3e57cc74-3e7a-4fc7-9bbb-f6c83252db01
User-Agent: Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.11 (KHTML, like Gecko) Chrome/23.0.1271.97 Safari/537.11
Accept: */*
Accept-Encoding: gzip,deflate,sdch
Accept-Language: en-US,en;q=0.8
Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.3
Cookie: JSESSIONID=908D73C50F09E75C9A0D674C4CB33D2F; ROUTEID=.1; __unam=3c3246b-13bc693352d-aa1535c-1

但是使用此代码

headerParams = {'Authorization':'bearer t-7614f875-8423-4f20-a674-d7cf3096290e'};
    obj = {
        type: 'get',
        url: 'https://api.sandbox.slcedu.org/api/rest/v1/students/test1',
        headers: headerParams,
    data: [],
    dataType: 'json',
    processData: false,
    success: function(data) {
        console.log('success');
        console.log(data);
    }
};

  jQuery.ajax(obj);

它发送像这样没有传递值，它的请求类型也变成了OPTION而不是GET，这里是控制台日志

Accept: */*
Accept-Encoding gzip, deflate
Accept-Language en-US,en;q=0.5
Access-Control-Request-Headers  authorization
Access-Control-Request-Method   GET
Connection  keep-alive
Host    api.sandbox.slcedu.org
Origin  http://localhost
User-Agent  Mozilla/5.0 (Windows NT 6.1; rv:17.0) Gecko/20100101 Firefox/17.0

有谁能告诉我怎么能这样传递它授权：bearer t-3e57cc74-3e7a-4fc7-9bbb-f6c83252db01

由于

Answer 1

使用beforeSend预请求回调，我们可以实现这一点。

$.ajax({
url: 'https://api.sandbox.slcedu.org/api/rest/v1/students/test1',
type: 'GET',
beforeSend: function (xhr) {
    xhr.setRequestHeader('Authorization', 'Bearer t-7614f875-8423-4f20-a674-d7cf3096290e');
},
data: {},
success: function () { },
error: function () { },
});

Answer 2

您可以使用ajaxSetup

为所有请求设置它

$.ajaxSetup({
    beforeSend: function(xhr) {
        xhr.setRequestHeader('Authorization', '...');
    }
});

另一个选项，使用“标题”键指定。

var settings = {
    "async": true,
    "crossDomain": true,
    "url": "https://api.example.com/action",
    "method": "POST",
    "headers": {
        "Content-Type": "application/x-www-form-urlencoded",
        "Authorization": "Bearer eyJraWQiOiJBbWZJSXU3UFhhdXlUbHM3UmNyZmNIQUd1MUdCWkRab2I0U05GaVJuWUFJPSIsImFsZyI6IlYYYjU2In0.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.fV4bgaKwXx-HjrBmGtBnSzaDHdP0JEeJ0sbE6MzuOJYWafT5gWfh9pLtkpUv-mgsnX3cVIWDVKC0H8_XM4ziUhsulZIRBwTiSca0CfABvanuMdbdjk1iK70aUxsrjHX0gK4SDUi4Zl6JNGws_SRbVi9Yq_ntx7ttXfUpZHjimfZ2mLidOLUruYctG1V_gU-dLD6CARCUbGh5aRk5nwX_5-HBUTbBVPYK3sXcVg2YRk63d-p3TITA5hoOEj9lxtHs3ZM7ZqNPl0XPUGghxdbvWnpSIUKrFLugRHqCiWxC38ZYiBhP0NDYoEMaOI-UrnEH1W6j-kr3fnH2LD5wOMJ_8Q"

}

$.ajax(settings).done(function (response) {
    console.log(response)
})

设置请求标头jQuery Ajax
