我正在尝试通过添加library(ggplot2)
set.seed(123)
nobs <- 1000
dat <- data.frame(var1=sample(LETTERS[1:3],nobs, T),
var2=sample(LETTERS[1:2],nobs,T),
var3=sample(LETTERS[1:3],nobs,T),
y=rnorm(nobs))
p1 <- ggplot(dat, aes(x=var1, y=y)) +
geom_boxplot(aes(fill=var2), position=position_dodge(.9)) +
facet_wrap(~var3) +
stat_summary(fun.y=mean, geom="point", aes(group=var2), position=position_dodge(.9),
color="black", size=4)
和Content-Type执行以下操作来下载从REST发送的zip文件：
服务器侧
Content-Disposition客户端：
另一方面，客户端期望@Produces("application/x-zip-compressed")
public Response export(@PathParam("username") String username,
@Context UriInfo ui) {
long timeStamp = new Date().getTime();
String exportedFolder = "/home/madmin/pods/"+username+"/download/";
String Path = ui.getRequestUri().toString()
.replace(replaceMe + username, "");
Path = Path.replace("http://", "https://");
Path = Path.replace(",system/export", "");
String outputZipFile = exportedFolder+"exported_on_"+timeStamp+".zip";
String sourceFolder = null;
File file = new File(exportedFolder);
if (!file.exists()) {
if (file.mkdirs()) {
System.out.println("Directory is created!");
} else {
System.out.println("Failed to create directory for exporting!");
//return ;
}
}
constructGraphs cGraphs = new constructGraphs(Path, username);
sourceFolder = cGraphs.writeGraphFiles();
generateZipFile appZip = new generateZipFile(sourceFolder,outputZipFile);
appZip.generateFileList(new File(sourceFolder));
appZip.zipIt(outputZipFile);
//Read the outputZipFile as inputStream and return it
FileInputStream fileIs = null;
try {
fileIs = new FileInputStream(outputZipFile);
} catch (IOException e) {
throw new WebApplicationException(404);
}
String fileName= outputZipFile.substring(outputZipFile.lastIndexOf("/")+1, outputZipFile.length());
return Response.status(Status.OK).entity(fileIs).header("Content-Disposition","attachment; filename = "+fileName).build();
}
如下：
application/x-zip-compressed文件没有弹出，而是在响应中看到输入流。
我在这里做错了吗？任何帮助都会非常感激。

使用AJAX是不可能的，我假设你在这种情况下使用angularjs http serivce。请参阅：Why threre is no way to download file using ajax request?。
您有不同的选择来解决您的问题。 例如：easiest way to open a download window without navigating away from the page 或How do you serve a file for download with AngularJS or Javascript?
