我正在尝试将文件扩展名从.xlsx更改为.csv。
到目前为止我有这个语法并且工作得很好。
raw_file=test_file.xlsx
echo "${raw_file%.xlsx}.csv"
test_file.csv
但如果我尝试将.xlsx分配给变量，它就不再起作用了。
f=.xlsx
echo "${raw_file%.$f}.csv"
test_file.xlsx.csv

问题是你有“。”在变量（“。xlsx”）和替换表达式（“。$ f”）中，所以它试图删除“..xlsx”。您需要将句点仅放在其中一个位置，然后它才能起作用：
$ raw_file=test_file.xlsx
$ extwithoutdot=xlsx
$ echo "${raw_file%.$extwithoutdot}.csv" # Here the "." is in the expression
test_file.csv
$ extwithdot=.xlsx
$ echo "${raw_file%$extwithdot}.csv" # Here the "." is in the variable
test_file.csv
$ echo "${raw_file%.$extwithdot}.csv" # Here the "." is in both -- it fails
test_file.xlsx.csv

您可以使用raw_file=test_file.xlsx
f=.xlsx
echo $(basename "$raw_file" "$f").csv
# -> test_file.csv
命令，例如
basename但请记住， let passingDict : [String:Any] = [
"fname" : YourValue,
"lname":YourValue,
"email" : YourValue,
"password" : YourValue,
"countryCode": YourValue,
"mobileNumber": YourValue,
"verificationType":YourValue,
]
let signup_url = ApiList.base_url + ApiList.signup_url
singletonclass.instance.Post_API_Call(passingDict, Url: signup_url, HittingApi: "SIGN_UP_URL")
func Post_API_Call(_ Parame: NSDictionary, Url: String, HittingApi: String)
{
var Api_Resp_Err = String()
var Api_Resp_Dict = NSDictionary()
do
{
let jsonData = try JSONSerialization.data(withJSONObject: Parame, options: [])
let fullListURL = Url
let url = URL(string: Url)!
var request = URLRequest(url: url)
request.httpMethod = "POST"
request.setValue("application/json; charset=utf-8", forHTTPHeaderField: "Content-Type")
request.httpBody = jsonData
let task = URLSession.shared.dataTask(with: request) { data,response,error in
if error != nil {
DispatchQueue.main.async(execute: {
Api_Resp_Err = (error?.localizedDescription)!
})
return
}
do
{
if let responseJSON = try JSONSerialization.jsonObject(with: data!, options: []) as? NSDictionary
{
if responseJSON.count > 0
{
DispatchQueue.main.async(execute: {
let statusCode = responseJSON.object(forKey: "code") as? String ?? ""
let message = responseDict.object(forKey: "Message") as? String ?? ""
})
}
else
{
}
}
else
{
DispatchQueue.main.async(execute: {
Api_Resp_Err = "Data Issue"
})
}
}
catch
{
DispatchQueue.main.async(execute: {
Api_Resp_Err = "Catch Issue"
})
}
}
task.resume()
}
catch
{
DispatchQueue.main.async(execute: {
//print("Server Issue catch II")
})
}
}
还会从文件名中删除所有前导目录名称。
