平常我們對(duì)接第三方都是以json的數(shù)據(jù)進(jìn)行數(shù)據(jù)交互的，這次第三方接口只支持form-data格式的表單數(shù)據(jù)，傳json數(shù)據(jù)對(duì)方不支持，通過(guò)百度和嘗試各種方案最終完美解決，后期再慢慢優(yōu)化吧。還有一個(gè)問(wèn)題，數(shù)據(jù)中包含中文的戶，到第三方是亂碼的，經(jīng)過(guò)百度參考前輩的經(jīng)驗(yàn)，完沒(méi)解決addTextBody亂碼問(wèn)題。記錄下工作中遇到的一個(gè)小問(wèn)題！

請(qǐng)求通過(guò)httpClient上傳文件

postman這樣傳的數(shù)據(jù)格式

httpcomponent框架MultipartEntityBuilder addTextBody中文亂碼

// 使用addPart+ StringBody代替addTextBody，解決中文亂碼

// builder.addTextBody(entry.getKey(), entry.getValue());

ContentType contentType = ContentType.create(HTTP.PLAIN_TEXT_TYPE, HTTP.UTF_8);
StringBody stringBody = new StringBody(entry.getValue(),contentType);
builder.addPart(entry.getKey(), stringBody);文章來(lái)源地址http://www.zghlxwxcb.cn/news/detail-544099.html
