XMLHttpRequest | 手动发送请求让我得到 2111 个字符的响应，但使用 XMLHttpRequest 响应的长度为 179

Question

I basically copy-pasted the MDN code, and I triple checked the URL. I can't find the reason as to why the responses differ. For reference, here is my code: Edit: Didn't see cookies got sent, I'm sorry

 function getUsernames(str) { console.log(str) } function reqListener() { alert(getUsernames(this.responseText)); } var oReq = new XMLHttpRequest(); oReq.addEventListener("load", reqListener); oReq.open("GET", "https://www.instagram.com/graphql/query/?query_hash=c76146de99bb02f6415203be841dd25a&variables=%7B%22id%22%3A%2217199917378%22%2C%22include_reel%22%3Atrue%2C%22fetch_mutual%22%3Atrue%2C%22first%22%3A24%7D"); oReq.responseType = "arraybuffer"; oReq.send(); oReq.onload = function(e) { var arraybuffer = oReq.response; // not responseText console.log(arraybuffer) /* ... */ }

Answer 1

Seems the xmlhttprequest is truncated and does not contain the data you want unless you have key (auth)

Here is something hacky: How can I get a user's media from Instagram without authenticating as a user?

You also have two load handlers. You likely mean this

 function getUsernames(str) { return JSON.parse(str); // of course do something with this when complete } function reqListener() { console.log(getUsernames(this.responseText)); } var oReq = new XMLHttpRequest(); oReq.addEventListener("load", reqListener); oReq.open("GET", "https://www.instagram.com/graphql/query/?query_hash=c76146de99bb02f6415203be841dd25a&variables=%7B%22id%22%3A%2217199917378%22%2C%22include_reel%22%3Atrue%2C%22fetch_mutual%22%3Atrue%2C%22first%22%3A24%7D"); oReq.responseType = "text"; oReq.send();

Answer 2

Okay, so I just found out that in the headers cookies got send. After clearing my cookies, I got the same result as the program. I thank you all for your participation!
