新浪微薄份额2（分享）

上一篇文章描述了webview获得accessToken方法。那么我们说一下分享。

分享有两个接口，他们是post要求

https://api.weibo.com/2/statuses/update.json//纯文本界面共享

https://upload.api.weibo.com/2/statuses/upload.json //文本图片分享接口

private static final String ADD_PIC_T = "https://upload.api.weibo.com/2/statuses/upload.json";
private static final String ADD_T = "https://api.weibo.com/2/statuses/update.json";	
private static final String[] ADD_SHARE_PARAMS = { "access_token", "status", "long", "lat" , "rip"};

ApiInfo.java

public class ApiInfo {
	private static final String TAG = "ApiInfo";

	public static final int REQ_GET = 0;
	public static final int REQ_POST = 1;
	public static final int REQ_PUT = 2;

	private String method;
	private String host;
	private int requstType;
	private String[] paramNames;
	private Map<String, Object> params;

	private String filePath;

	public ApiInfo(String host, String method, String[] paramNames) {
		this.host = host;
		this.method = method;
		this.paramNames = paramNames;
		this.params = new HashMap<String, Object>();
	}

	public ApiInfo(String host, String method, String[] paramNames, int requestType) {
		this.host = host;
		this.method = method;
		this.paramNames = paramNames;
		this.requstType = requestType;
		this.params = new HashMap<String, Object>();
	}

	public String getFilePath() { 
		return filePath;
	}

	public void setFilePath(String filePath) {
		this.filePath = filePath;
	}

	public int getRequstType() {
		return requstType;
	}

	public void setRequstType(int requstType) {
		this.requstType = requstType;
	}

	public String getMethod() {
		return method;
	}

	public void setMethod(String method) {
		this.method = method;
	}

	public String[] getParamNames() {
		return paramNames;
	}

	public void setParamNames(String[] paramNames) {
		this.paramNames = paramNames;
	}

	public Map<String, Object> getParams() {
		if (params == null)
			params = new HashMap<String, Object>();
		return params;
	}

	public void setParams(Map<String, Object> params) {
		this.params = params;
	}

	public String getHost() {
		return host;
	}

	public void setHost(String host) {
		this.host = host;
	}
        public String getPlainUrl() {
		StringBuffer url = new StringBuffer();
		url.append(host);
		url.append(method);
		url.append("?");
		for (String paramName : getParamNames()) {
			LogInfo.d(TAG, "paramName=" + paramName);
			url.append(paramName);
			url.append("=");
			if (getParams().get(paramName) != null)
				try {
					url.append(URLEncoder.encode(getParams().get(paramName).toString(), "UTF-8"));
				} catch (UnsupportedEncodingException e) {
					e.printStackTrace();
				}
			url.append("&");
		}
		url.deleteCharAt(url.length() - 1);
		return url.toString();
	}
}

分享方法share2Weibo,拼接请求參数

public void share2Weibo(String content, String img) {
	ApiInfo apiInfo = new ApiInfo(ADD_PIC_T, "", ADD_PIC_T_PARAMS, ApiInfo.REQ_POST);
	Map<String, Object> params = new HashMap<String, Object>();
	params.put(ADD_PIC_T_PARAMS[0], oAuth.accessToken);
	params.put(ADD_PIC_T_PARAMS[1], content);
	params.put(ADD_PIC_T_PARAMS[2], "0.0");
	params.put(ADD_PIC_T_PARAMS[3], "0.0");
	params.put(ADD_PIC_T_PARAMS[4],  AndroidUtils.GetHostIp());
	apiInfo.setParams(params);
	String imgPath = null;
	if (!TextUtils.isEmpty(img))
		if (IOUtils.getCacheImageFile(context, img) != null) {//通过path推断图片是否存在
			imgPath = IOUtils.getCacheImageFile(context, img).getAbsolutePath();
		} else
			apiInfo.setHost(ADD_T);//假设图片不存在更改分享内容的url

	new ShareTask(apiInfo).execute(imgPath);
}

ShareTask.java 联网发送post请求，分享内容

class ShareTask extends AsyncTask<String, Object, Json> {

	private ApiInfo apiInfo;

	public ShareTask(ApiInfo apiInfo) {
		this.apiInfo = apiInfo;
	}

	@Override
	protected Json doInBackground(String... params) {
		String result = "";
		if (params.length > 0 && params[0] != null) {
			result = new String(httpClient.uploadFile(apiInfo.getPlainUrl(), "pic", params[0]));
		} else
			result = new String(httpClient.request(apiInfo.getPlainUrl(), apiInfo.getRequstType() == ApiInfo.REQ_POST));
		LogInfo.d(TAG, "result:" + result);
		Json json = new Json(result);
		return json;
	}

	@Override
	protected void onPostExecute(Json result) {
	
		super.onPostExecute(result);
	}
}
