我一直在尝试将标头中的cookie发送到this url并抓取json响应。要发送的Cookie是Cookie：var iter = 10;
function asyncFunction(i) {
return new Promise(resolve => {
let response = confirm("Iterations left: " + i + ". Proceed to next iteration?");
resolve(response);
});
}
function iterator(iter){
// Wait for the response of the asyncFunction to proceed to next iteration
asyncFunction(iter).then((response)=>{
// Proceed if true
if(response) {
iterator(iter-1);
}
});
}
iterator(iter);
在使用python的请求库时，我获得了所需的json数据。这是我的Python代码。
"tid=fpopRl3WSNQ1tdxH1bZTTR15LhuBRnJg;"这是我的蜘蛛代码：
import requests
url = "https://amazon.zappos.com/mobileapi/janus/recos/get?item=9280133&limit=5&limit_0=5&limit_1=10&limit_2=10&limit_3=15&teen=4826753&widgets=detail-1,detail-2,detail-vis-sims,detail-3"
cookie = "tid=fpopRl3WSNQ1tdxH1bZTTR15LhuBRnJg;"
headers = {'cookie':cookie}
requests.get(url, headers=headers).json()
但是蜘蛛给出了这个错误。
def parse(self, response):
cookie = "tid=fpopRl3WSNQ1tdxH1bZTTR15LhuBRnJg;"
url = "https://amazon.zappos.com/mobileapif/janus/recos/get?item=9280133&limit=5&limit_0=5&limit_1=10&limit_2=10&limit_3=15&teen=4826753&widgets=detail-1,detail-2,detail-vis-sims,detail-3"
request = scrapy.Request(url=url, cookies ={'cookie': cookie},callback=self.parsejson)
yield request
def parsejson(self, response):
jsonresponse = json.loads(response.text)
print(jsonresponse)
答案 0 :(得分：2)
您需要对$query = 'SELECT * FROM transactions';
$orderBy = ' ORDER BY processingTime DESC';
if (isset($request->search['status'])) {
$query .= ' WHERE status = '.$request->search['status'];
}
$query .= $orderBy;
$query = DB::select($query);
$query->get();
使用$query = 'SELECT * FROM transactions';
$orderBy = ' ORDER BY processingTime DESC';
$where = [1];
if ($condition1) {
$where[] = 'condition1 = '.$condition1;
}
if ($condition2) {
$where[] = 'condition2 = '.$condition2;
}
$where = implode(' AND ', $where);
$query .= ' WHERE '.$where;
$query .= $orderBy;
$query = DB::select($query);
$query->get();
格式：
key: value 更新似乎您在cookies中有错字（mobileapi f 与mobileapi）。检查更新的代码。
