OCR拍照搜題
簡(jiǎn)介
HI，您好，歡迎使用學(xué)而思網(wǎng)校AI開放平臺(tái)OCR拍照搜題接口服務(wù)。
本文檔主要針對(duì)需要集成HTTP API的技術(shù)研發(fā)工程師，詳細(xì)描述OCR拍照搜題能力相關(guān)的技術(shù)內(nèi)容。您可以通過(guò)
接口能力

接口能力簡(jiǎn)要描述
api 地址
OCR拍照搜題
檢測(cè)上傳圖像中的文字，進(jìn)行 AI 文字識(shí)別，然后搜索相關(guān)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(yǔ)言，均可以通過(guò)http或https調(diào)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(luò)上的圖片 URL 地址
圖片數(shù)據(jù)
請(qǐng)求圖片需經(jīng)過(guò)base64編碼：圖片的base64編碼指將一副圖片編碼成字符串?dāng)?shù)據(jù)，便于網(wǎng)絡(luò)傳輸請(qǐng)求。您可以首先得到圖片的二進(jìn)制，進(jìn)行base64編碼后，然后再進(jìn)行urlencode(注意你所使用的網(wǎng)絡(luò)工具或網(wǎng)絡(luò)庫(kù)有沒有默認(rèn)的urlencode功能,如果沒有，需要你自己顯式轉(zhuǎn)化)。
轉(zhuǎn)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(zhǎng)邊不能超過(guò)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(shí)別范圍
目前，OCR識(shí)別接口服務(wù)支持多種類型文字，包括：
中文打印體識(shí)別
英文打印體識(shí)別
表格識(shí)別
拼音識(shí)別
請(qǐng)求方式
HTTP 方法：POST
請(qǐng)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(guò)urlencode格式化請(qǐng)求體。

Content-Type
application/x-www-form-urlencoded
urlencode介紹
在請(qǐng)求 API 的 post 請(qǐng)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(shí)，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(zhuǎn)換為百分號(hào)編碼形式，這就是 urlencode格式化操作。
部分語(yǔ)言的第三方包內(nèi)部做了 urlencode 編碼，不進(jìn)行 urlencode 格式化也可以正常進(jìn)行 API 請(qǐng)求，但 ? ?是進(jìn)行 urlencode 格式化之后，一定可以通過(guò)請(qǐng)求。所以我們推薦您對(duì)請(qǐng)求體中的參數(shù)進(jìn)行 urlencode 操作。
