python - Mechanize [Errno 10054] 现有连接被远程主机强行关闭

Question

我在网上找遍了，但我找不到解决这个错误的方法。有人知道这是怎么回事吗？

代码:

for index in range(len(sections)):      
    br.select_form(name="win1")
    post_url, post_data, headers =  br.form.click_request_data()
    post_data = post_data.replace("ICAction=None", "ICAction=DERIVED_CLSRCH_SSR_CLASSNAME_LONG$"+str(index))
    r = br.open(post_url, post_data) ##ERROR ON THIS LINE
    html = r.read()

    if index < range(len(sections)):
        br.select_form(name="win1")
        post_url, post_data, headers =  br.form.click_request_data()
        post_data = post_data.replace("ICAction=None", "ICAction=CLASS_SRCH_WRK2_SSR_PB_BACK")
        r = br.open(post_url, post_data)
        html = r.read()

弄明白了，post 数据很大，我猜它弄乱了请求。我修剪了它，现在工作正常。
