使用python发布json数据时出现问题

Question

我正在尝试从LeetCode-CN获取所有提交的代码，我需要获取问题的翻译。卷曲命令可以给我想要的结果：

curl 'https://leetcode-cn.com/graphql' -H 'authority: leetcode-cn.com' -H 'origin: https://leetcode-cn.com' -H 'content-type: application/json' -H 'referer: https://leetcode-cn.com/problemset/all/' --data '{"operationName":"getQuestionTranslation","variables":{},"query":"query getQuestionTranslation($lang: String) {\n translations: allAppliedQuestionTranslations(lang: $lang) {\n title\n questionId\n __typename\n }\n}\n"}'

但是以下python代码无法正常工作：

def loadChnProblemList(client):
    query = {
        "operationName": "getQuestionTranslation", 
        "variables": {}, 
        "query": "query getQuestionTranslation($lang: String) {\n  translations: allAppliedQuestionTranslations(lang: $lang) {\n    title\n    questionId\n    __typename\n  }\n}\n"}
    headers = {
        "content-type": "application-json",
        "origin": "https://leetcode-cn.com",
        "referer": "https://leetcode-cn.com/problemset/all/"
    }
    response = requests.post("https://leetcode-cn.com/graphql", headers=headers, data=json.dumps(query))
    data = json.loads(response.text)
    print(data)

服务器将响应：

{"errors":[{"message":"Must provide query string."}]}'

为什么curl命令起作用但python代码不起作用？

Shijith是正确的-修复了将内容类型更改为application / json的问题。有关更多详细信息，请参见requests docs。
