OCR拍照搜題
簡介
HI，您好，歡迎使用學而思網(wǎng)校AI開放平臺OCR拍照搜題接口服務。
本文檔主要針對需要集成HTTP API的技術研發(fā)工程師，詳細描述OCR拍照搜題能力相關的技術內容。您可以通過

OCR拍照搜題
檢測上傳圖像中的文字，進行 AI 文字識別，然后搜索相關的試題。
http://openapiai.xueersi.com/v1/api/img/ocr/photo_search
適用范圍
任意操作系統(tǒng)，任意編程語言，均可以通過http或https調用本接口。
圖像發(fā)送方式
圖像數(shù)據(jù)支持兩種形式發(fā)送：
URL
網(wǎng)絡上的圖片 URL 地址
圖片數(shù)據(jù)
請求圖片需經過base64編碼：圖片的base64編碼指將一副圖片編碼成字符串數(shù)據(jù)，便于網(wǎng)絡傳輸請求。您可以首先得到圖片的二進制，進行base64編碼后，然后再進行urlencode(注意你所使用的網(wǎng)絡工具或網(wǎng)絡庫有沒有默認的urlencode功能,如果沒有，需要你自己顯式轉化)。
轉碼方式可參考
注意: 圖片的base64編碼是不包含圖片頭的，如(data:image/jpg;base64,)
圖片大小
不能大于4MB
長邊不能超過4096px
短邊不能小于15px
圖像類型支持
圖像數(shù)據(jù)支持以下原生類型：
jpg
png
jpeg
bmp
文字識別范圍
目前，OCR識別接口服務支持多種類型文字，包括：
中文打印體識別
英文打印體識別
表格識別
拼音識別
請求方式
HTTP 方法：POST
請求 URL：http://openapiai.xueersi.com/v1/api/img/ocr/photo_search
注意: Content-Type為application/x-www-form-urlencoded，然后通過urlencode格式化請求體。

urlencode介紹
在請求 API 的 post 請求參數(shù)中含有圖片url地址或base64字符。url地址 或 base64 字符作為參數(shù)傳遞時，需要把 中文 以及 '/' 做一下編碼，防止解析中出現(xiàn)歧義，從而符合url的規(guī)范。
將中文 以及 '/' ?轉換為百分號編碼形式，這就是 urlencode格式化操作。
部分語言的第三方包內部做了 urlencode 編碼，不進行 urlencode 格式化也可以正常進行 API 請求，但 ? ?是進行 urlencode 格式化之后，一定可以通過請求。所以我們推薦您對請求體中的參數(shù)進行 urlencode 操作。
