iOS使用HTTPPOST上傳圖像和文本我是iOS的新手，我正在嘗試用以下方式上傳圖片和文本multi-part form encoding在iOS。這個curl等價物是這樣的：curl -F "param1=value1" -F "[email protected]" "http://some.ip.address:5000/upload"這個curl命令中返回預期的正確響應。JSON.問題：我一直收到一個HTTP 400請求，這意味著我在編寫HTTPPOST主體時做錯了什么。我所做的：作為參考，我試過FlickrAPIIOS應用程序“帖子大小太大了！”和目標C：如何使用HTTPPOST上傳圖像和文本？..但是，我一直得到一個HTTP 400。我試過ASIHttpRequest但是那里有一個不同的問題(回調沒有被調用)。但是，我沒有進一步研究這個問題，因為我聽說開發人員已經停止支持這個庫了：http://allseeing-i.com/[request_release];有人能幫幫我嗎？
