Example of generating a presigned post policy which has the condition that only jpeg images + * can be uploaded, and applies the public read acl to each image uploaded, and making the POST + * request: + * + *
{@code

+ *
+ * PostPolicyV4 policy = storage.generateSignedPostPolicyV4(
+ * BlobInfo.newBuilder("my-bucket", "my-object").build(),
+ * 7, TimeUnit.DAYS, fields, conditions);
+ *
+ * HttpClient client = HttpClientBuilder.create().build();
+ * HttpPost request = new HttpPost(policy.getUrl());
+ * MultipartEntityBuilder builder = MultipartEntityBuilder.create();
+ *
+ * for (Map.Entry entry : policy.getFields().entrySet()) {
+ * builder.addTextBody(entry.getKey(), entry.getValue());
+ * }
+ * File file = new File("path/to/your/file/to/upload");
+ * builder.addBinaryBody("file", new FileInputStream(file), ContentType.APPLICATION_OCTET_STREAM, file.getName());
+ * request.setEntity(builder.build());
+ * client.execute(request);
+ * }
