我想打印一个图片网址,但它给了我特殊的字符。我尝试了file_get_contents - Special characters in URL - Special case中的每个解决方案,但它没有解决它。
我的代码:
$urlgeo = "http://geodata.nationaalgeoregister.nl/top25raster/wms?request=GetMap&service=WMS&version=1.3.0&request=GetMap&layers=top25raster&styles=&bbox=146000,451000,149000,454000&width=600&height=600&srs=EPSG:28992&format=image/png";
print file_get_contents($urlgeo);

您正在从API服务请求PNG图像,您应该使用适当的标题来显示图像,
builder.Register(c => new ExternalEventsBus(CreateExternalEventBus()))
.As<IExternalEventsBus>().SingleInstance();
public class ExternalEventsBus:IExternalEventsBus
{
private IBus Bus;
public ExternalEventsBus(IBus bus)
{
Bus = bus;
}
public async Task Send(object message, Guid documentProviderId)
{
await Bus.Advanced.Routing.Send(documentProviderId.ToString("n"), message);
}
public Task Send(object message, DocumentProvider documentProvider)
{
if (!string.IsNullOrWhiteSpace(documentProvider.RebusQueueConnectionString))
return Send(message, documentProvider.Id);
return Task.FromResult(true);
}
public void Dispose()
{
if(Bus!=null)
Bus.Dispose();
}
}

如果您想要显示图片,请尝试以下操作:
<?php
$urlgeo = "http://geodata.nationaalgeoregister.nl/top25raster/wms?request=GetMap&service=WMS&version=1.3.0&request=GetMap&layers=top25raster&styles=&bbox=146000,451000,149000,454000&width=600&height=600&srs=EPSG:28992&format=image/png";
echo "<img src='data:image/png;base64," . base64_encode(file_get_contents($urlgeo)) . "'>";
?>
它获取图像并在base64中编码。
稍后如果你需要原始图像数据,只需要base64_decode
:
$raw_image = base64_decode($encodedImg):
其中$encodedImg
是base64编码的字符串。 $raw_imag
将包含原始图像数据!
