最近，需要對(duì)客戶(hù)的接口做一個(gè)包裝，然后供自己公司別的系統(tǒng)調(diào)用，客戶(hù)接口是用HTTP URL實(shí)現(xiàn)的，我想用HttpClient包進(jìn)行請(qǐng)求，同時(shí)由于請(qǐng)求的URL是HTTPS的，為了避免需要證書(shū)，所以用一個(gè)類(lèi)繼承DefaultHttpClient類(lèi)，忽略校驗(yàn)過(guò)程。
1.寫(xiě)一個(gè)SSLClient類(lèi)，繼承至HttpClient

剛開(kāi)始不是很明白BasicNameValuePair的用法，后來(lái)慢慢摸索了一下，發(fā)現(xiàn)BasicNameValuePair是存儲(chǔ)鍵值對(duì)的類(lèi)，當(dāng)添加新的key和value值，它會(huì)自動(dòng)給裝換成http的格式，=和&符號(hào)，比如https://xxx.xxx.xxx/xxx/xxxx/delivery?delivery_code=DQZZSM2A×tamp=1479198840000&sign=F209C33FEADE99F93E8970FA0F68D3EB，我們都不用自己進(jìn)行拼接和匹配了，個(gè)人覺(jué)得它用起來(lái)還是挺方便而且準(zhǔn)確度也高，希望可以幫助到大家！
以上就是小編為大家?guī)?lái)的JAVA利用HttpClient進(jìn)行POST請(qǐng)求(HTTPS)實(shí)例全部?jī)?nèi)容了，希望大家多多支持服務(wù)器之家~
