我尝试将pdf文件从我的应用主捆绑包上传到服务器。 但是我在上传时没有收到任何错误，但是从服务器收到响应时却出现错误

 Message = "The resume must be a file of type: docx, doc or pdf.";
    Success = 0;

后端团队指出这是一个编码错误，但我不知道我在哪里出错。 请帮我解决这个问题。

Answer 1

PDF：用于上传pdf文件的MIME类型和文件名

filename =“ .pdf” mimetype =“ application / pdf”

DOCX：docx的mimetype和文件名上传filename =“ .docx” mimetype =“ application / application / vnd.openxmlformats-officedocument.wordprocessingml.document”

这对我有用

Answer 2

doc文件的文件名和mimetype以本机api上传到服务器

  func createBodyWithParameters(parameters: [String: Any]?, filePathKey: String?, fileData: NSData, boundary: String) -> NSData {

    let body = NSMutableData();

    if parameters != nil {
        for (key, value) in parameters! {
            body.appendString(string:"--\(boundary)\r\n")
            body.appendString(string: "Content-Disposition: form-data; name=\"\(key)\"\r\n\r\n")
            body.appendString(string: "\(value)\r\n")
        }
    }

         filename = ".doc"
         mimetype = "application/msword"

    body.appendString(string: "--\(boundary)\r\n")
    body.appendString(string: "Content-Disposition: form-data; name=\"\(filePathKey!)\"; filename=\"\(filename)\"\r\n")
    body.appendString(string: "Content-Type: \(mimetype)\r\n\r\n")
    body.append(fileData as Data)
    body.appendString(string: "\r\n")
    body.appendString(string: "--\(boundary)--\r\n")

    return body

}
