无法将图像数据用作OCR API的参数 [英] Unable to use Image data as a parameter to the OCR API
问题描述
我无法将图像数据用作OCR API的参数。我尝试了
测试控制台以及jquery AJAX 。我得到400 Bad< g class =" gr_ gr_168 gr-alert gr_gramm undefined Grammar multiReplace"数据-GR-ID =" 168" id =" 168"> request< / g> 或无效的图片格式。可以
有人分享正确的请求吗？在将图像URL作为参数发送到API时，我能够恢复文本。来自测试控制台的带有Image二进制文件的任何样本或成功请求都将有用。
这样的东西？
< html>
< head>
< script src =" http://ajax.googleapis.com/ajax/libs/jquery/1.9.0/jquery.min.js">< / script>
< script type =" text / javascript">
ocr = function（）{
var f =
（'＃file-input'）。get（0）.files [0];
.ajax（{
url：" http：//api.projectoxford.ai/vision/v1/ocr" ;,
beforeSend：function（xhrObj）{
//请求标头
xhrObj.setRequestHeader（" Content-Type"，" application / octet-stream"）;
xhrObj.setRequestHeader（" Ocp-Apim-Subscription-Key"， "YOUR-API-KEY"）;
}，
类型：" POST"，
//请求正文
数据：f，
processData：false
}）
.done（函数（数据）{
alert（" success"）;
//显示数据
console.log（ JSON.stringify（data））;
}）
.fail（function（e）{
alert（" error"）;
debugger;
}）;
}
< / script>
< / head>
< body>
< p>< input type =" file" ID = QUOT;文件输入与QUOT;><峰; br />
< button onclick =" ocr（）"> ocr！< / button>
< / p>< / body>
< / html>
I am unable to use image data as a parameter to the OCR API. I tried with the testing console as well as the jquery AJAX. I am getting 400 Bad <g class="gr_ gr_168 gr-alert gr_gramm undefined Grammar multiReplace" data-gr-id="168" id="168">request</g> or Invalid Image format. Can someone share the correct request for the same? I am able to get the text back while sending the image URL as a parameter to the API. Any sample or successful request from testing console with the Image binaries will be Helpful.
Something like this?
<html> <head> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.0/jquery.min.js"></script> <script type="text/javascript"> ocr = function() { var f =
('#file-input').get(0).files[0];
.ajax({ url: "http://api.projectoxford.ai/vision/v1/ocr", beforeSend: function(xhrObj){ // Request headers xhrObj.setRequestHeader("Content-Type","application/octet-stream"); xhrObj.setRequestHeader("Ocp-Apim-Subscription-Key","YOUR-API-KEY"); }, type: "POST", // Request body data: f, processData: false }) .done(function(data) { alert("success"); //display data console.log(JSON.stringify(data)); }) .fail(function(e) { alert("error"); debugger; }); } </script> </head> <body> <p><input type="file" id="file-input"><br/> <button onclick="ocr()">ocr!</button> </p></body> </html>
