选择 Network----XHR------Request URL-------From Data


将data里的数据，添加符号:

data['i'] = content
data['from'] = 'AUTO'
data['to'] = 'AUTO'
data['smartresult']= 'dict'
data['client']= 'fanyideskweb'
data['salt']= '15968850678607'
data['sign']='a002a0944e7b48f4d35241d16f8290d3'
data['lts']='1596885067860'
data['bv']= '02a6ad4308a3443b3732d855273259bf'
data['doctype']= 'json'
data['version']='2.1'
data['keyfrom']= 'fanyi.web'
data['action']='FY_BY_CLICKBUTTION'
