用JS或JQ能连续发3个请求吗?

Question

大体流程如下:

第一步,获取token,请求URL如下:

http://124.**.**.**:63192/api/3.8/auth/signin

返回如下:(获取token)

<?xml version='1.0' encoding='UTF-8'?>
<tsResponse xmlns="http://tableau.com/api" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://tableau.com/api http://tableau.com/api/ts-api-3.8.xsd">
<credentials token="YN7jdyJ8T7S8AMjwM9gWmA|LH0iXKLrGYgMG8ArA4YGhGG1V1icr8Fb">
<site id="baccc514-ef62-48dc-b964-c153c3f6c464" contentUrl=""/>
<user id="5a328439-9b3d-4197-ab4c-f334839061f7"/>
</credentials>
</tsResponse>

第二步,用token请求获取站点ID:

请求URL:

http://124.**.**.**:63192/api/3.9/sites

返回结果如下:

{
    "pagination": {
        "pageNumber": "1",
        "pageSize": "100",
        "totalAvailable": "2"
    },
    "sites": {
        "site": [
            {
                "id": "baccc514-ef62-48dc-b964-c153c3f6c464",
                "name": "Default",
                "contentUrl": "",
                "adminMode": "ContentAndUsers",
                "disableSubscriptions": true,
                "state": "Active",
                "revisionHistoryEnabled": true,
                "revisionLimit": "25",
                "subscribeOthersEnabled": false,
                "allowSubscriptionAttachments": true,
                "guestAccessEnabled": true,
                "cacheWarmupEnabled": true,
                "dataAlertsEnabled": true,
                "commentingEnabled": true,
                "commentingMentionsEnabled": true,
                "flowsEnabled": false,
                "extractEncryptionMode": "disabled",
                "dataAccelerationMode": "enable_selective",
                "catalogingEnabled": false,
                "derivedPermissionsEnabled": true,
                "webExtractionEnabled": true,
                "askDataMode": "EnabledByDefault",
                "runNowEnabled": true,
                "userVisibilityMode": "FULL",
                "requestAccessEnabled": true,
                "authoringEnabled": true,
                "customSubscriptionEmailEnabled": false,
                "customSubscriptionFooterEnabled": false,
                "namedSharingEnabled": true
            }
        ]
    }
}

第三步,使用站点ID获取站点内容:
请求URL:

http://124.**.**.**:63192/api/3.9/sites/baccc514-ef62-48dc-b964-c153c3f6c464/workbooks

返回结果:

{
"pagination": {
"pageNumber": "1",
"pageSize": "100",
"totalAvailable": "18"
},
"workbooks": {
"workbook": [
{
"project": {
"id": "fd43940e-9581-11ea-b965-a72ac3f8c8fb",
"name": "默认值"
},
"owner": {
"id": "5a328439-9b3d-4197-ab4c-f334839061f7",
"name": "admin"
},
"tags": {},
"dataAccelerationConfig": {
"accelerationEnabled": false
},
"id": "14def8ac-ae8b-42ee-8c22-723827f5022e",
"name": "工作簿 1",
"description": "",
"contentUrl": "1",

Answer 1

你这3个请求是有关联性的，所以不能同时发送出去。只能在成功后的回调函数里再进行下一个请求；

Answer 2

async requestMethod() {
    await getToken();
    await getId();
    await getContent();
    // more other code
}
