如何设置Airbnb Api“扩展”范围？

我试图通过普通的HTTP请求来刮擦Airbnb ，并注意到了一些东西。

假设我们使用此搜索字符串：“纽约，纽约，美国”。

我可以用来获得所需结果的最简单的工作请求（从不必要的标题和字段中取出）是：

GET /api/v3/ExploreSections?operationName=ExploreSections&locale=en&currency=USD&variables=%7B%22isInitialLoad%22%3Atrue%2C%22hasLoggedIn%22%3Afalse%2C%22cdnCacheSafe%22%3Afalse%2C%22source%22%3A%22EXPLORE%22%2C%22exploreRequest%22%3A%7B%22metadataOnly%22%3Afalse%2C%22version%22%3A%221.8.3%22%2C%22itemsPerGrid%22%3A20%2C%22placeId%22%3A%22ChIJOwg_06VPwokRYv534QaPC8g%22%2C%22query%22%3A%22New%20York%2C%20New%20York%2C%20United%20States%22%2C%22cdnCacheSafe%22%3Afalse%2C%22screenSize%22%3A%22large%22%2C%22isInitialLoad%22%3Atrue%2C%22hasLoggedIn%22%3Afalse%7D%2C%22removeDuplicatedParams%22%3Atrue%7D&extensions=%7B%22persistedQuery%22%3A%7B%22version%22%3A1%2C%22sha256Hash%22%3A%2282cc0732fe2a6993a26859942d1342b6e42830704b1005aeb2d25f78732275e7%22%7D%7D HTTP/2
Host: www.airbnb.com
X-Airbnb-Api-Key: d306zoyjsyarp7ifhu67rjxn52tv0t20
Accept-Encoding: gzip, deflate

在这一点上，API密钥几乎是公开的，所以不关心。

“变量”参数的可读内容是：

{
  "isInitialLoad": true,
  "hasLoggedIn": false,
  "cdnCacheSafe": false,
  "source": "EXPLORE",
  "exploreRequest": {
    "metadataOnly": false,
    "version": "1.8.3",
    "itemsPerGrid": 20,
    "placeId": "ChIJOwg_06VPwokRYv534QaPC8g",
    "query": "New York, New York, United States",
    "cdnCacheSafe": false,
    "screenSize": "large",
    "isInitialLoad": true,
    "hasLoggedIn": false
  },
  "removeDuplicatedParams": true
}

“扩展”参数的可读内容是：

{
  "persistedQuery": {
    "version": 1,
    "sha256Hash": "82cc0732fe2a6993a26859942d1342b6e42830704b1005aeb2d25f78732275e7"
  }
}

我试图找出哈希的来源。

看来它是从GraphQl查询中计算出来的，但我什么都不知道，也没有关于它的文档。

有帮助吗？

I am trying to scrape AirBNB by plain HTTP requests and noticed something.

Let's say we use this search string: "New York, New York, United States".

The simplest working request (striped off from unnecessary headers and fields) I can use to get the desired results is this:

GET /api/v3/ExploreSections?operationName=ExploreSections&locale=en¤cy=USD&variables=%7B%22isInitialLoad%22%3Atrue%2C%22hasLoggedIn%22%3Afalse%2C%22cdnCacheSafe%22%3Afalse%2C%22source%22%3A%22EXPLORE%22%2C%22exploreRequest%22%3A%7B%22metadataOnly%22%3Afalse%2C%22version%22%3A%221.8.3%22%2C%22itemsPerGrid%22%3A20%2C%22placeId%22%3A%22ChIJOwg_06VPwokRYv534QaPC8g%22%2C%22query%22%3A%22New%20York%2C%20New%20York%2C%20United%20States%22%2C%22cdnCacheSafe%22%3Afalse%2C%22screenSize%22%3A%22large%22%2C%22isInitialLoad%22%3Atrue%2C%22hasLoggedIn%22%3Afalse%7D%2C%22removeDuplicatedParams%22%3Atrue%7D&extensions=%7B%22persistedQuery%22%3A%7B%22version%22%3A1%2C%22sha256Hash%22%3A%2282cc0732fe2a6993a26859942d1342b6e42830704b1005aeb2d25f78732275e7%22%7D%7D HTTP/2
Host: www.airbnb.com
X-Airbnb-Api-Key: d306zoyjsyarp7ifhu67rjxn52tv0t20
Accept-Encoding: gzip, deflate

At this point, that API key is pretty much public, so not a concern.

The readable content of the "variables" parameter is this:

{
  "isInitialLoad": true,
  "hasLoggedIn": false,
  "cdnCacheSafe": false,
  "source": "EXPLORE",
  "exploreRequest": {
    "metadataOnly": false,
    "version": "1.8.3",
    "itemsPerGrid": 20,
    "placeId": "ChIJOwg_06VPwokRYv534QaPC8g",
    "query": "New York, New York, United States",
    "cdnCacheSafe": false,
    "screenSize": "large",
    "isInitialLoad": true,
    "hasLoggedIn": false
  },
  "removeDuplicatedParams": true
}

The readable content of the "extensions" parameter is this:

{
  "persistedQuery": {
    "version": 1,
    "sha256Hash": "82cc0732fe2a6993a26859942d1342b6e42830704b1005aeb2d25f78732275e7"
  }
}

I am trying to figure out where that hash comes from.

It seems it's calculated from a GraphQL query but I don't know anything else and there is no documentation about it.

Any help?

我遇到了同样的问题（想获得价格），然后在har文件中调查了您可以使用Chrome获得的har文件后，我发现您从称为pdpplatformroute.xxx.js的JavaScript文件中获得此

值只是为了加载文件pdpplatformroute.xxx.js，然后解析文件以获取“ protiveID”。

如果有帮助，这就是我这样做的方式。

// contentPage is the HTML content of the listing page (e.g. https://www.airbnb.com/rooms/1234567)
function getPdpPlatformRouteUrl(contentPage) {
  return 'https://a0.muscache.com/airbnb/static/packages/web/en/frontend/gp-stays-pdp-route/routes/' + `${contentPage}`.match(/(PdpPlatformRoute\.\w+\.\js)/)?.[1];
}

// textContent is the JS content that you get when you fetch the previously found URL
function getSha256(textContent) {
  return `${textContent}`.match(/name:'StaysPdpSections',type:'query',operationId:'(.*)'/)?.[1];
}

I had the same issue (wanted to get the prices) and after investigating in the HAR files that you can get with Chrome, I found out that you get this value from a Javascript file called PdpPlatformRoute.xxx.js

The steps to get this hash are simply to load the file PdpPlatformRoute.xxx.js, then to parse the file to get an "operationId".

If this helps, this is how I did this.

// contentPage is the HTML content of the listing page (e.g. https://www.airbnb.com/rooms/1234567)
function getPdpPlatformRouteUrl(contentPage) {
  return 'https://a0.muscache.com/airbnb/static/packages/web/en/frontend/gp-stays-pdp-route/routes/' + `${contentPage}`.match(/(PdpPlatformRoute\.\w+\.\js)/)?.[1];
}

// textContent is the JS content that you get when you fetch the previously found URL
function getSha256(textContent) {
  return `${textContent}`.match(/name:'StaysPdpSections',type:'query',operationId:'(.*)'/)?.[1];
}
