HTTP方法--Put 还是 Patch?

下面这四个就不需要解释了：  
POST = 新增  
GET = 读取  
PUT = 更新  
DELETE = 刪除

**POST or PUT?**

**PUT** puts a file or resource at a specific **URI**, and exactly at that URI. If there’s already a file or resource at that URI, PUT **replaces** that file or resource. If there is no file or resource there, PUT **creates** one. PUT is idempotent, but paradoxically PUT responses are not cacheable.

**POST** sends data to a specific **URI** and expects the resource at that URI to handle the request. The web server at this point can determine what to do with the data in the context of the specified resource. The POST method is not idempotent, however POST responses are cacheable so long as the server sets the appropriate Cache-Control and Expires headers.

**应用：**  
POST:- Used when the client is sending information or data to the server—for example, filling out an online form (i.e. Sends a large amount of complex data to the Web Server).

PUT:- Used when the client is sending a replacement document or uploading a new document to the Web server under the request URL.

**PUT or PATCH?**  
**PUT** replace the **ENTIRE RESOURCE** with the new representation provided (no mention of related resources in the spec from what i can see)

**PATCH** **replace** parts of the source resource with the values provided AND|OR other parts of the resource are updated that you havent provided (timestamps) AND|OR updating the resource effects other resources (relationships)

通俗讲，全部更新和局部更新。

**put与patch比也不是一无是处：**

PATCH /groups/{group id} { "attributes": { "status": "active" }}
    response: 200 OK
    
    PATCH /groups/{group id} { "attributes": { "status": "deleted" }}
    response: 406 Not Acceptable

PUT /groups/{
       group id} { "attributes": { "status": "active" }}
    response: 406 Not Acceptable
    
    PUT /groups/{
       group id} { "attributes": { "name": .... etc. "status": "active" }}
    response: 201 Created or 200 OK, depending on whether we made a new one.

**curl实现get、post、put、patch**

**get**

CURL *hnd = curl_easy_init();
    
    curl_easy_setopt(hnd, CURLOPT_CUSTOMREQUEST, "GET");
    curl_easy_setopt(hnd, CURLOPT_URL, "url");
    
    struct curl_slist *headers = NULL;
    headers = curl_slist_append(headers, "key1: value1");
    headers = curl_slist_append(headers, "key2: value2");
    headers = curl_slist_append(headers, "content-type: application/json");
    curl_easy_setopt(hnd, CURLOPT_HTTPHEADER, headers);
    
    curl_easy_setopt(hnd, CURLOPT_POSTFIELDS, "{\"username\":\"damulaoshi\",\"password\":\"password\",\"nickname\":\"大木老师\"}");
    CURLcode ret = curl_easy_perform(hnd);

**post**

CURL *hnd = curl_easy_init();
    
    curl_easy_setopt(hnd, CURLOPT_CUSTOMREQUEST, "POST");
    curl_easy_setopt(hnd, CURLOPT_URL, "url");

    curl_easy_setopt(hnd, CURLOPT_HTTPHEADER, headers);

    CURLcode ret = curl_easy_perform(hnd);

**put**

CURL *hnd = curl_easy_init();
    
    curl_easy_setopt(hnd, CURLOPT_CUSTOMREQUEST, "PUT");
    curl_easy_setopt(hnd, CURLOPT_URL, "url");
    
    struct curl_slist *headers = NULL;

    headers = curl_slist_append(headers, "cache-control: no-cache");
    headers = curl_slist_append(headers, "if-match: e73c24173415c8140501d50f9918ee5886970d16");

    curl_easy_setopt(hnd, CURLOPT_POSTFIELDS, "{\"status\":\"closed\"}");
    
    CURLcode ret = curl_easy_perform(hnd);

**patch**

CURL *hnd = curl_easy_init();
    
    curl_easy_setopt(hnd, CURLOPT_CUSTOMREQUEST, "PATCH");
    curl_easy_setopt(hnd, CURLOPT_URL, "url");
    
    struct curl_slist *headers = NULL;

    headers = curl_slist_append(headers, "content-type: application/json");
    curl_easy_setopt(hnd, CURLOPT_HTTPHEADER, headers);
    
    curl_easy_setopt(hnd, CURLOPT_POSTFIELDS, "{\"nickname\":\"苍老师\",\"realname\":\"苍井空\"}");
    
    CURLcode ret = curl_easy_perform(hnd);
