用正则表达式处理Python请求的响应
我对正则表达式不太熟悉，现在想从python-requests的响应中提取字典样式的字符串。这里是从HTML响应中截取的代码片段：
</div>
</div>
<div id="image-canvas-caption" class="a-row">
<div class="a-column a-span12 a-text-center">
<span id="canvasCaption" class="a-color-secondary"></span>
</div>
</div>
<div class="collections-collect-button"></div>
</div>
</div></div>
</div>
<script type="text/javascript">
maintainHeight = function(){
var mainHolder = document.getElementById("main-image-container");
var imgTagWrapperId = document.getElementById("imgTagWrapperId");
if(mainHolder && typeof mainHolder != 'undefined'){
var width = mainHolder.offsetWidth;
var ratio = 0.84;
var shouldAutoPlay = false;
var videoSizes = [[262, 445], [294, 500], [323, 550], [356, 606], [399, 679]];
var containerHeight = width/ratio;
containerHeight = Math.min(containerHeight, 700);
mainHolder.style.height = containerHeight + "px";
if(imgTagWrapperId && typeof imgTagWrapperId !== 'undefined' ){
imgTagWrapperId.style.height = containerHeight + "px";
}
var landingImage = document.getElementById("landingImage");
var imageHeight = Math.min(containerHeight, 679);
var imageWidth = Math.min(width, 399);
if(landingImage){
landingImage.style.maxHeight = imageHeight + "px";
landingImage.style.maxWidth = imageWidth + "px";
}
if(shouldAutoPlay){
if(landingImage){
var autoPlayWidth=0, autoPlayHeight=0;
for(var i=0; i < videoSizes.length; i++){
if( autoPlayWidth < videoSizes[i][0] ){
autoPlayWidth = videoSizes[i][0];
autoPlayHeight = videoSizes[i][1];
}
}
if( autoPlayWidth > 0 && autoPlayHeight > 0 ){
var videoRatio = autoPlayWidth/autoPlayHeight;
// increasing height of the slate image by 1px (and width with the ratio) so that black lines doesn't appear on ipad on right side.
var isIpad = navigator.userAgent.match(/ipad/i);
if( isIpad ){
containerHeight = containerHeight + 1;
}
landingImage.style.width = containerHeight * videoRatio + "px";
landingImage.style.height = containerHeight + "px";
}
}
}
}
};
maintainHeight();
window.onresize = function(){
maintainHeight();
};
P.when('A').register("ImageBlockATF", function(A){
var data = {
'colorImages': { 'initial': [{"hiRes":"http://ecx.images-amazon.com/images/I/717%2BCE-2hWL._UL1500_.jpg","thumb":"http://ecx.images-amazon.com/images/I/41KLRCK3m%2BL._SR38,50_.jpg","large":"http://ecx.images-amazon.com/images/I/41KLRCK3m%2BL.jpg","main":{"http://ecx.images-amazon.com/images/I/717%2BCE-2hWL._UY445_.jpg":[262,445],"http://ecx.images-amazon.com/images/I/717%2BCE-2hWL._UY500_.jpg":[294,500],"http://ecx.images-amazon.com/images/I/717%2BCE-2hWL._UY550_.jpg":[324,550],"http://ecx.images-amazon.com/images/I/717%2BCE-2hWL._UY606_.jpg":[357,606],"http://ecx.images-amazon.com/images/I/717%2BCE-2hWL._UY679_.jpg":[400,679]}},{"hiRes":"http://ecx.images-amazon.com/images/I/61BabEwSG0L._UL1500_.jpg","thumb":"http://ecx.images-amazon.com/images/I/2160xHhT4zL._SR38,50_.jpg","large":"http://ecx.images-amazon.com/images/I/2160xHhT4zL.jpg","main":{"http://ecx.images-amazon.com/images/I/61BabEwSG0L._UX342_.jpg":[342,95],"http://ecx.images-amazon.com/images/I/61BabEwSG0L._UX385_.jpg":[385,107],"http://ecx.images-amazon.com/images/I/61BabEwSG0L._UX425_.jpg":[425,119],"http://ecx.images-amazon.com/images/I/61BabEwSG0L._UX466_.jpg":[466,130],"http://ecx.images-amazon.com/images/I/61BabEwSG0L._UX522_.jpg":[522,146]}}]},
'colorToAsin': {'initial': {}},
'holderRatio': 0.84,
'holderMaxHeight': 700,
'useStretchyImageFix': true
};
A.trigger('P.AboveTheFold'); // trigger ATF event.
return data;
});
我只需要：
'colorImages': { 'initial': [{"hiRes":"http://ecx.images-amazon.com/images/I/717%2BCE-2hWL._UL1500_.jpg","thumb":"http://ecx.images-amazon.com/images/I/41KLRCK3m%2BL._SR38,50_.jpg","large":"http://ecx.images-amazon.com/images/I/41KLRCK3m%2BL.jpg","main":{"http://ecx.images-amazon.com/images/I/717%2BCE-2hWL._UY445_.jpg":[262,445],"http://ecx.images-amazon.com/images/I/717%2BCE-2hWL._UY500_.jpg":[294,500],"http://ecx.images-amazon.com/images/I/717%2BCE-2hWL._UY550_.jpg":[324,550],"http://ecx.images-amazon.com/images/I/717%2BCE-2hWL._UY606_.jpg":[357,606],"http://ecx.images-amazon.com/images/I/717%2BCE-2hWL._UY679_.jpg":[400,679]}},{"hiRes":"http://ecx.images-amazon.com/images/I/61BabEwSG0L._UL1500_.jpg","thumb":"http://ecx.images-amazon.com/images/I/2160xHhT4zL._SR38,50_.jpg","large":"http://ecx.images-amazon.com/images/I/2160xHhT4zL.jpg","main":{"http://ecx.images-amazon.com/images/I/61BabEwSG0L._UX342_.jpg":[342,95],"http://ecx.images-amazon.com/images/I/61BabEwSG0L._UX385_.jpg":[385,107],"http://ecx.images-amazon.com/images/I/61BabEwSG0L._UX425_.jpg":[425,119],"http://ecx.images-amazon.com/images/I/61BabEwSG0L._UX466_.jpg":[466,130],"http://ecx.images-amazon.com/images/I/61BabEwSG0L._UX522_.jpg":[522,146]}}]}
从 var data 中提取。我对正则表达式不太在行，这方面我搞不定。请帮帮我。谢谢。
