所以我有一個代碼,我得到了它從uploading to Imgur v3 using Java https errors和我得到的第50行錯誤的「列表」告訴我類型列表不是通用的;它不能與參數進行參數[了HTTPClient]
The type List is not generic; it cannot be parameterized with arguments
我能做些什麼解決這個問題?
我正在使用http://hc.apache.org/httpclient-3.x/並希望使用他們的v3 API將圖像上傳到imgur。
編輯:改變導入後,我現在得到這些錯誤。
解決了這個問題,但給我兩個更多的錯誤。
nameValuePairs.add(new BasicNameValuePair("image", dataImage));
The method add(NameValuePair) in the type List is not applicable for the arguments (BasicNameValuePair)
而且
post.setEntity(new UrlEncodedFormEntity(nameValuePairs));
The constructor UrlEncodedFormEntity(List) is undefined
我編輯我的答案現在... // @ user2526311它現在固定。 – hexafraction
如何在運行程序時返回「null:null」,還是應該在新問題中發佈? – user2526311
@ user2526311不要在開始時將其設置爲空,將其設置爲虛擬或空字符串。 – hexafraction
