Python 使用请求模块访问api

curl命令按预期工作。但类似的python代码却没有

# curl -X POST -H "Content-Type: application/json" -d '{"img_url":"http://tleyden-misc.s3.amazonaws.com/blog_images/ocr_test.pnge","engine":"tesseract"}' http://35.154.148.131:9292/ocr

You can create local variables for the pipelines within the template by
prefixing the variable name with a "$" sign. Variable names have to be
composed of alphanumeric characters and the underscore. In the example
below I have used a few variations that work for variable names.

我尝试了以下python代码：

import requests
url = 'http://35.154.148.131:9292'
data = {"img_url":"http://tleyden-misc.s3.amazonaws.com/blog_images/ocr_test.png","engine":"tesseract"}  
r = requests.post( url, json={'json_payload': data})

这将返回以下错误：

b'<h1>OpenOCR is running!<h1> Need <a href="http://www.openocr.net">docs</a>?'

b'OpenOCR正在运行！需要吗？”

如何使用数据参数发布字典？

我就是这样做到的：

import requests
url = 'http://35.154.148.131:9292/ocr'
data = {"img_url":"http://tleyden-misc.s3.amazonaws.com/blog_images/ocr_test.png","engine":"tesseract"}  

r = requests.post( url, json=data )

结果

u'You can create local variables for the pipelines within the template by\nprefixing the variable name with a "$" sign. Variable names have to be\ncomposed of alphanumeric characters and the underscore. In the example\nbelow I have used a few variations that work for variable names.\n\n'

只调用

r=requests.post（url，json=data）

怎么样？据我所知，这是使用它的方式。另外，在Python代码中，URL中缺少

/ocr

端点。
