Files could neither be deleted nor downloaded - example 2

[janphoffmann]

In the example 2 I could not download the uploaded file and could not delete the uploaded file.

I traced the issue to: line 99: if(!SPIFFS.exists(filename)
the filename is defined with: const char *fileName = request->getParam("name")->value().c_str(); (line 94)

I did a rather ugly workauround with the following code:

    char *cstr1 = (char*)malloc(strlen(request->getParam("name")->value().c_str())+1);
    strcpy(cstr1,"/");
    strcat(cstr1, fileName);
    if (!SPIFFS.exists(cstr1)){
    .
    .
     request->send(SPIFFS, cstr1, "application/octet-stream");
     .
    .
    SPIFFS.remove(cstr1);
    .
    .
    free(cstr1);

Same issue here, did this modification:

char dataPath[120] = {0};
memset(dataPath, 0x0, sizeof(dataPath));
strcpy(dataPath, gifFile.path());

and replaced all fileName to dataPath

That was my work around.

Thank you @janphoffmann & @viniciusro , I suspect libraries have changed since this was first published which is causing this. When I get time over the next couple weeks I will test and update.

I remplaced this line:
const char *fileName = request->getParam("name")->value().c_str();
with this:
String fileName = "/"+String(request->getParam("name")->value() );

Works like a charm. PR.

In my case, only '/' was missing before the file name.

if (!FFat.exists(String('/') + fileName)) {
